I bought 6-pack of similar type of LED light from different manufacture before.  It worked for about 2 months and LED started to die out.  I bought 4x of them from Great Eagle Lighting so far and it's outlasting other manufacture's LEDs.  I'm sold on LEDs from Great Eagle Lighting Corporation!

I bought these 6 months ago. Gifted 4 and kept 1 for myself. I use a rechargable battery, so the voltage isn't as high as a regular alkeline, but the light output is still great. I was lucky and bought this as a $10 lightning deal, yet wouldn't hesitant to pay the regular $15 price. It's a great way to have one in your pocket, by your bed, in your car, etc.

I see plenty of the exact same style with other brandings, but not for the same price. I'm sure they were all made in the same factory in China, so whichever brand you snag should be fine.

I've tried multiple G4 LED lamps and these are the best out there by far.  I replaced my indoor 20 watt halogen 12V AC cabinet lights and I'm pleased especially with the color (3000K) that is an exact match to my other 3000K lights. Also, these are even brighter than my 20 watt halogens, but these are not 40 watt halogen replacements at their rated output of 280 lumen as 40 watt halogens are in the 400 lumen range so please update LE.  Now I hope they last.

These are pretty awesome bulbs.  I've bought six of them to replace 25 and 40 watt incandescent bulbs - these little 3-watters are almost as bright as a 40 watt.  They are truly "warm white" and are instant-on.

Since I use these bulbs in often-used lamps (on for more than 10 hours a day), these bulbs will pay for themselves within two months.

UPDATE: all of these bulbs are still running strong. I love them more and more each day. If they're out of stock, it might be my fault. My electric bill has dropped substantially - these have definitely paid off.

UPDATE 2: Two of my six bulbs have failed within the past two weeks, after roughly 2,000 hours of service each.  Reduced to one star due to poor life.  A few months later, and four of the six bulbs have failed, with far less than 20% of advertised life on the bulb.  The four that failed were all from the same package, so perhaps it was "just" a bad lot?

UPDATE 3: I bought another set of 4 despite the awful reliability of one of my earlier purchases.  The two that remain are older and have a slightly different design (no "shoulder").  The newest bulbs have a slightly different design yet again.  We'll see if they last, and if they do I'll slowly adjust the stars I gave to this product.  Too bad that manufacturers that are well known for quality don't enter the "3 watt, E26" bulb space.

UPDATE 4: The new batch is running strong.  Some are on 24x365, and others are in normal fixtures that are used 8 or more hours a day.  This new batch is 100% reliable, and I love the quality.  I speculate that the failed bulbs were knock-offs, given their different design.

UPDATE 5: It has been a year since I installed my last batch of these, with 3 bulbs on 24x365, and 3 others on roughly 18x365.  All running strong, no failures.  Calculated that my savings with these bulbs has been over $145 so far. By next year it'll be about $300.

I am so happy I bought this light. I had a Surefire P2X Fury and I now like the Pelican 7000 more. It is brighter, has more output modes, is programable, has a battery life check, and is just as high quality as the more expensive lights. You can quickly change between output modes so if you want to use the 64 lumens for close work such as paperwork, or you can use the 602 lumens for searching or blinding the crap out of someone. I even purchased one more light as well as the rechargeable kit both from the same vendor (CVPKG) who has both outstanding customer service and shipping.

I bought this unit from the company's website and like an idiot I did not check amazon.  I could have saved a good amount of money had I not been in such a hurry to buy.  I was unaware amazon sold these though there store.  Even overpaying like I did I think they are a great product.  I work for an emergency management agency and we have to equip our cars at our own cost so I figured if I was going to have to buy it myself I would buy something over the top.  This thing is stronger than my new HID lights that came stock in my car.  Holy cow these are bright! They match the color of my HID lights (when observed in the car looking at the road)  from GM and it allows me to light up the road like a airplane coming in for a landing.  They are small cube type lights and I was surprised how small the box was that I got in the mail. I thought I only go one unit in the mail but when I opened it up there was two.  Install was great and the cables were very nice and big.  Nice quality quick connects that plug from the cable into each light. The relay they use is rated at 60 amps.  Major overkill for a light that uses 4 amps or so but I like the fact the company didn't go cheap. I can use the relay to power more lamps from them in the future on the same circuit.  All in all there is really not much to complain about with the exception of the price.  Not everyone can afford these and I almost like it like that.  It is nice to have higher end products that offer great quality.  One look at the torture test video they posted on the main site and I was sold.  I took a video for you all to see but you have to remember that night videos are very hard to shoot.  The settings in the camera can over expose and under expose.  I took such a long video that I think there are many points in the video that give the viewer a good idea of how bright these are.  For the few amps they pull this is the next generation of lighting.  High output low current draw.

Bought this off my brothers Prime account.  Beautiful conversion kit and def long lasting and more or less the same price as buying halogen bulbs.  It has been a few months and still rocking.  No issues.  Highly recommend over halogen lights.  A friend helped me install the kit and said these would outlast halogen bulbs

I bought 4 of these for my garage, first only 3 to test them out, and a 4th after I saw how AWESOME these are.

I did a lot of review reading and research on LED lights before settling on these. I love all the LED advancements being made in lighting technology, and consider myself an eager early adopter. Though there are sometimes duds, Feit usually has it figured out with their LED products.

These come with pocket-slot screw mounting holes on the back, and also with short hang cables that snap into the same slot and thus can be used to hang these dow from the ceiling several inches.

The light is bright and white, much whiter than an incandescent, but not the annoying sick greenish hue that lots of fluorescences have in comparison. The light also distributes nicely.

I have used one of these to lug up into an attic that had not wired lighting. I say lug but this was is really fairly lightweight. Its just awkward carrying something so long up a ladder. In an already hot attic space, this DID NOT add any heat, which I appreciated!

I bought 4&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Leviton-125-15-Amp-660-Watt-125-Volt-2-Pole-2-Wire-Socket-To-Outlet-Adapter/dp/B001PCVTFC/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Leviton 125 15 Amp, 660 Watt, 125 Volt, 2-Pole, 2-Wire, Socket To Outlet Adapter</a>&nbsp;so that I can replace all the incandescent bulbs in my garage with these. It will be super bright, super white, and super nice to work in!

Really nice light. I have only had this for a few weeks as our patio was being installed, and recently had the opportunity to install them. The solar cells appear to give a good charge to the lights; in the "dim at dark and bright when motion" mode they easily last all night. I think they will probably last all night in full light mode IF you live in a place where they get plenty of sun. We do so these were a decent addition to our lighting.

First downside is one lamp has the on/off-mode switch deeply indented so it is difficult to press. Just part of the manufacturing process I suppose that it was not adjusted in the hole before gluing. If these hold up we will definitely buy more and easily recommend to neighbors.

Updated Oct 1: Second downside is longevity and the warranty process. These lights have been excellent until now. They last all night long and provide great light for our enclosed patio. However, recently one of the lights has started to flash between bright and dim intermittently with absolutely no motion in the area. I can stand about 4 feet away and it will switch to full brightness, and then seems to go back to the normal dim standby. But then it will start flashing bright-dim every few minutes. I first noted this several days ago while up at night. I don't see a way to remedy this, so bought another one as I don't want to drill new mounting homes in the fence.

The seller, while having a one year warranty, requires this be shipped back for repair or replacement. The cost of doing so which requires Priority Mail due to weight restrictions is more than the lamp cost. I think manufacturers do this so you will simply toss out the light and buy another rather than returning. Figure your cost per 6 months and decide whether this is the light for you.  Guess this is how I had to handle it.

So, really nice light but warranty experience was 1 star from my view. The ONLY reason I purchased this light again is because I didn't want to drill more holes in my fence. Otherwise I would have purchased another brand.

October 7: Yet another nag e-mail from this seller (the second is the past few days) asking for a positive review. I asked them not to bother me again but here they are with another nag e-mail. No, with their warranty policy being what it is I don't see the value of a light that lasts 6 months!

I bought this headlamp 2 years ago and another one last year. They are extremely bright and get used alot. The bulb on the first one started to go bad and the other one the battery box got destroyed (by no fault of the light or manufacturer). I sent an email to Xtreme Bright and within 3 days I had 2 brand new lights absolutely free. Talk about customer service and standing behind your products! They even followed up with an email to be sure I was completely satisfied with the new lights and to be sure the issue had been resolved. I will only be purchasing lights from Xtreme Bright from now on!

As a home builder, I have encouraged several clients in the past few years to at least purchase these lights for their heavy use locations. To date we have installed over 100 of these and have had zero failures and several very happy clients. The quality of light is excellent! The brightness is great for working or non-task areas. The range of dimming (about 10-90%) is excellent and appreciated by nearly all of my clients. A final bonus, this is a great product for exterior use. The lens is sealed which keeps wasps and other pests from nesting in the housing.
I have 20 installed in my own home (15 years old). We love the look and feel. Thankful there is no real heat gain during these Oklahoma summers. We have had these installed for over 18 months and have had no failures. Further, we began to see an immediate drop in electric costs.

Purchased a ten pack six months ago for landscape lightning.  For the ones that work lighting is great!  However they have be plagued with a 40% failure rate.  One was DOA, one at two weeks, one at two months and one at four months of use.  The bulbs are in use about 10 hours per day.

I've been in touch with Caryleds several times and they agreed to replace them.  I've waited plenty of time for them to arrive from China but they never make it.  This last time I was given a USPS tracking number and I can see the bulbs made it to the US but then it appears they were returned to China.

Anticipating caryleds follows through on the agreement to replace them I've given them 3 stars.  If they don't I'll adjust my review rating accordingly.

I'm not attempting to dim the bulbs.  One bulb flickered heavily before failing but I suspect this flickering is a bit different from the flickering others are noting related to dimming.

Update: I've increased my rating to 4 stars. Caryled's is very responsive and the fact that I haven't yet received the replacements appears to be a shipping issue not a caryled issue.

I've tried four of these R20 bulbs, as well as four of the Great Eagle R20 and four of the Philips R20 bulbs.

I'm replacing R20 45W incandescent bulbs, not PAR halogen bulbs, so this review will focus on the bulbs these LEDs are intended to replace. These weren't really meant to replace PAR halogen bulbs.

First, these Feit bulbs are my hands-down clear winners. The color is exactly like incandescent bulbs, they have a 93 CRI (the only R20s I could find that do), they don't buzz, they don't get any warmer than just warm anywhere on the bulb, and using a Cooper DAL06P-C1-K-L LED/CFL dimmer (which has both kick-start and dimmest-level adjustments), these are the ONLY R20 bulbs I've tried that dim down to nothing at the lowest level while dimming smoothly throughout the dimming range and restarting correctly at any level. They're also brighter than the incandescents they replaced. I'd recommend these to anyone.

While others like the Philips R20 bulbs, I didn't. All four of my samples had slightly different colors at lower light levels, they wouldn't dim below about 30% brightness on the same Cooper dimmer, and they dimmed in steps...but the steps happened at different levels for each bulb, probably due to manufacturing tolerances. While they were very bright with good color at full brightness, the dimming performance made me return all four of them to the big-box store. What's really strange is that the Philips R30 LED bulbs seem to have completely different electronics, since we use them with other identical Cooper dimmers in other parts of the house.

The Great Eagle R20 bulbs were my second clear choice, and while they dimmed smoothly, they also didn't dim enough on the same Cooper dimmer (they may dim lower on a Lutron LED dimmer, though). They're also a bit whiter than the Feit lamps. But they're very bright, and I liked them so much that I replaced the four CFLs in our garage with them, where they're brighter, and they'll likely stay that way in the winter when CFLs are too dim. These are also very good bulbs, but the Feits edged them out with the lowest dimming level.

Bottom line: if you want to replace your R20 45W incandescent bulbs, these Feit bulbs are just about perfect.

I've purchased 4 of these fixtures and all operate perfectly.  The housings are durable and the mounting brackets are simple yet effective.  These lights wire up in series without issue.

As others have said, rattling parts inside the fixture is not uncommon as the screws for the wire terminal blocks tend to come loose.  Of the four I purchased, only 1 had no rattles.  Likewise, only that 1 had wiring for the ground connection.  The other 3 had wiring for hot and neutral only.

The issue are minor and don't affect performance.  Light output is very good and the price is unbeatable.  I've already recommended them to friends and family looking to wire up lights in attics, garages, sheds, etc.  I'll definitely be buying more as I work through my project list.

Relative to price, these guys are truly making the best product out there right now. I've invested hundreds in trying out almost all the major manufacturers' stuff and I cannot say enough good things about the quality and value of the bulbs Hitlights is putting out. This 6W unit is my default solution for most areas, but I stepped up to the 9W in my front hallway and living areas for added brightness. In rare situations, like my kitchen prep area, I also use the 12W version.
There are only 2 situations where I don't use HitLights: when I'm looking for true "mood lighting" with exceptional warmth, I use the beautiful 8W Philips bulb, and for things like porch lights where I want max efficiency and can tolerate a slightly cooler temp, the 9W/900lm G7 bulb blows everything else away at 100 lumens per watt.

We have 4 RAB TallPack HPS dusk-to-dawn lights around our property.  Up until this purchase, I always purchased replacement bulbs by price.  This meant about $9-$10 and a Made in China label.  Some worked really well; most just didn't last.  This GE bulb is made in Hungary and costs more.  But not only does it look much better made and give more light at the same wattage, it seems to be much more reliable as well.  I'm sold.
