Ok, I bought this to replace my Craftsman (and I could be Bob Vila with all of it that I own).  I spent a little more than I normally would, but I can say it's been worth every penny.  I just drove 3" door screws without any problem.  The battery guage is awesome.  The drill is balanced, and very attractive.  I thought the light was a gimmick, but I actually really liked the feature.  It helped when the sun was setting, and my project was several hours past schedule.  Do NOT hesitate buying this.  You won't be sorry.  Very quick charge also.  I can't wait to buy the Sawzall next.

I had nothing but great results with this power supply, (I bought two 30W units). The two power supplies are set up to power my 'under-cabinet' strip lights in the kitchen and the other powers the strip lighting I installed in my desk cabinets.

The one in the kitchen is powering about 80 to 90 LEDs via a dimmer control switch similar to this one: http://smile.amazon.com/Dimming-Controller-Adjustable-Brightness-Zitrades/dp/B007V1B0W8/ref=pd_sim_sbs_hi_11?ie=UTF8&refRID=0WRFS0SA7CKQWY8BPERQ

The power to the LED strips were setup in a "parallel" configuration but I configured the lights in my desk cabinets 'in-line'. The advantage to the waterproof LED light strips and power supplies make them perfect for areas such as the kitchen where the possibility of water or some liquid to splash on them is high.

The waterproofing makes that a non-issue and you can clean any splashes that might occur easily with a damp cloth, (of course, unplug the power first just to be extra safe).
The price for this power supply was great and I have no doubt I'll be buying more soon!

OMG, i love this product.  Bought this for my dad, not only did it come with lifetime warranty, the product itself is so much more than is described.  Built to endure.  Potent and powerful bright LEDs.  Can't get my hands off of it honestly. Love it!

This small yet so power Led light packs a punch. Was amazed when i switched it on and place it on Full power! it was stronger than our house China Emergency LEd llight.

Simple yet so many applications it can be use with or on. Now i can have a much power flash/Light that i can bounce on the ceiling to have the "natural" light look of the pic.

As a photographer, i can even use this on my DSLR, i mount it on its hot shoe holder (nice thingking) and mount it off camera, on a light stand, and viola! can use it for video too! very many application, imagination is the only limitation.

Much faster than its 2.0 predecessor with built in LED indication.  Another quality product from PNY

I have tried many LED light bulbs over the last year or so claiming to be replacements for 50W + incandescents for use in normal fixtures, and this is the first bulb to actually exceed my expectations, and at a lower price than most of the competition.

The bulb is slightly whiter than warm white and it is bright - definitely brighter than a 60W incandescent bulb.  In fact I have used the first two I ordered to replace 50W halogen flood lamps in our kitchen and these LED bulbs provide a brighter light even though they are not directional like the halogen floods - they spread light over about 180 degrees compared to a typical flood's spread of 35 degrees.

These are the first LED bulbs I have seen that produce 100 lumens per Watt.  So 900 lumens from 9W. By replacing two halogen floods I have more light with 18W than I had before with 100W. These specs also make these bulbs among the first to truly exceed CFLs in efficiency, thus the review title of a "breakthrough in LED light bulbs".  And of course they bring the other major LED advantage of turning on almost instantly at full brightness, not to mention the lack of any mercury related disposal issues if indeed they ever need replaced.

(These bulbs are not dimmable so if your application requires that capability you will need another product. I have also purchased two&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Philips-409904-Dimmable-AmbientLED-12-5-Watt-A19-Light-Bulb/dp/B004IUMGV4/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Philips 409904 Dimmable AmbientLED 12.5-Watt A19 Light Bulb</a>s and if the weird appearance is not a problem these are an excellent choice if dimming is required and you need 800 lumens plus from the bulb.)

The guarantee is spectacular - if the bulb burns out during YOUR lifetime return it for a free replacement.  Of course this is only as good as the life of the company as well, but it does indicate the confidence that the vendor has in their product.

Also intriguing is that the bulb looks almost like a regular A19 incandescent bulb, with a silvery coating on the bottom half. It lacks the very visible and massive external heat-sinks of similar products. It remains to be seen whether this lack of a visible heat-sink will impact the bulb life and/or long term performance.

Anyway after two days of use I am delighted.  I have ordered 3 more.  I hope they add a true flood-light PAR20 form factor in the near future as well.

This thing is BRIGHT!

First impressions after a week of ownership:

It's amazing how far these lights have come in the last 4 or 5 years.  I replaced an old Blackstar 240 watt unit (drew about 120 watts of power) with this, and the difference is amazing.  Although this unit is almost identical in overall dimensions, its substantially heavier, with more fan area and well-finned heat sinks visible through the fan intake grates.  It draws roughly 200 Watts, but seems more than twice as bright as the old unit.  I also note that it has a "fuller" spectrum compared to earlier lights, which focused more on the red and blue extremes, for a net magenta look.  Whether this balance affects PAR positively remains to be seen.

I have been slowly replacing all the lights in my house with LED lights, and these just blew my mind.  I ended up buying around 20 lights in all because they are very bright, Instant on (no one second delay that you might see in other lights), and the color temp is very close to the incandescent that I was replacing.  They are not perfect, but FAR better than the florescent lights that I tried.  I purchased some of the 1100 lumen bulbs for my kitchen (15 can lights) and a few more of the 700 lumen bulbs for stairs and hallways.  I love these lights (brightness, color, and price are all perfect)

I HIGHLY recommend them to anyone!!!

Tried out 4 different LED GU10s for my track in my kitchen. The previous 50W (300W total) bulbs were of course nice, but a power hog and extremely hot.
These bulbs were the best because -
1) Dimmable, for the most part. They did not flicker.
2) Warm color
3) Soft spread for general lighting that I needed
Post test, I purchased a whole bunch of them and now I am using 36W where I previously had 300W for the same quality of light. LED advancements have come a long way!

Ok, I will admit it here on Amazon: I have a flashlight fetish.  Whew, there, done.  I feel so much better now.

With that full disclosure behind us, this $16 flashlight is wildly bright.  It is brighter than every flashlight I own, and I have many.  My brightest halogen Streamlight cannot touch this especially when you consider the size differences.

I agree most are thinking it is another cheap import product that is often just rebranded for the PepBoys check stand or Lowes, regardless, the quality is reliable enough. I am tough on it and it is holding up great.  It was not DOA, no complaints about the switch on the base; just a very small palm sized light that has huge light.

When I first got it, I forgot about the 3.7v battery issue.  It is an odd size for the average handheld light.  I picked up a few Duracell CR17345 3v batteries at my local Kmart (yeah still in business).  Together these were over the limits of the light's 3.7v rating but no one had a single 3.7v lithium battery so I tried it.  Although they did work and lit up my entire living room with a clear white HID quality, after using them I noticed the light was getting hot (Danger, Danger, High Voltage!) and ended up buying the suggested rechargeable Tenergy 18650's.  Those arrived and I was worried the doubled 3v batteries were going to be way brighter than (1) 18650 3.7v.  Not the case. Perfect.

So as a guy that really likes collecting different flashlights, you really need to try this.  It will not disappoint.  The only exposure you have may be the quality could be hit or miss based on other reviews.  Mine was perfect.  I am buy two more for my kids' to have in their cars. Btw, the Tenergy rechargeable is exceptional.  I left the light on for (3) hours and I could barely see any dimming.  I had to turn it off because it does get pretty freaking warm.  Great hand warmer if get stranded on winter evening and have to hoof it.  Do be sure to get the battery with the protective PCB.  There are many out there, look for the over limit PCB.  Will save the light.  Batteries are pricey in relation to the light but well worth it.  I use my modestly and still on the first full charge.  I bought (3) batteries thinking it would suck them up fast; not the case.

Enjoy!!

I have not been given anything in exchange for this review, unlike others (no judgement, just a statement of fact).  Also, I don't like random LED manufacturers, and prefer the innovators like Cree, when I can buy them (LED snob!).  But I couldn't find any such bulbs in a minimal profile, like these.  I'm not inclined to purchase an unknown brand and... Yet... I am fairly pleased so far.  Pay attention to the very well done video reviews that highlight how well these perform in multi-bulb fixtures.  It's the lumens, not the wattage that counts, as others have highlighted, and in my vanity arrays these perform indistinguishably well in comparison to 60W equivalent Cree's that they replaced.  The 60W's were overkill.  These are cool, bright, and a better fit for the purpose.  Very happy that I purchased them.  If they last, I will be super happy with them.  Again, look at other reviews' very well done videos that seem to accurately capture these bulbs in action... But if you're a skeptic like me, give them a shot.  I'm about to order some more :)

Update October 2016: Two bulbs out of 18 I have in use blew months 1 and 3 of usage.  I continue to use these in kitchen and bathroom arrays of 3-6 fixtures, and find that they provide enough light in this configuration.  Minus one star, but still meeting my expectations of good but not perfect bulbs.

SUPER BRIGHT! When I opened the box for this I thought "how bright could this be? It looks like one small LED light inside." I plugged the light into the battery and made a huge mistake. I looked directly at the light and turned it on. WOW! I severely underestimated the power of this light! I literally almost fell off my chair in shock! After I regained sight in my right eye and composure I went through and checked out the light in more detail. Here's what I found...

BRIGHTNESS: ridiculous!! It has to be as bright or brighter than a vehicle's headlight. In the full sun day-lit office this thing looked bright. At home in the dark it was seriously a shock how bright this thing is. I could actually use this as a defense against a robber in the middle of the night. It would blind them!

FUNCTIONALITY: The battery pack is separate from the light and attaches with a cable. The battery comes in a cloth case that has velcro to attach to a bike frame. There is then a cable that attaches to the light or the power block to charge it. So the light can stay fixed to the bike even when charing the battery. The back of the light is well thought out as well. There are 2 buttons that are backlit so you can see them in the dark. The left button turns on a ring of LED's that cast a nice glow if you don't want the full headlight on. When you press that button again the ring starts strobing, adding more safety to your night-time bike riding. The right button turns on the SUPER BRIGHT headlight. It can be on while the ring is on/flashing. You can also press the headlight button 2 more times giving you 3 brightness settings.

QUALITY: Every part of this product is made out of quality material. The buttons feel solid and I believe they will hold up to long-term use. The power cable is a decent gauge and feels like it will hold up long-term without breaking or fraying. The cable has a screw on hold as well to help support it and give it a longer life. When holding it and squeezing around the edges there is not any noise indicating loose construction. Everything feels tight and solid! It also comes with a nice head attachment with thick elastic bands and it has a nice tight fit. (I did not try putting the light on the head attachment...I imagine the external battery would be a bit heavy on my head!).

OVERALL IMPRESSION: I love this thing! It's impressively bright, useful in many situations (biking, camping, security). I recently DJ'd a wedding reception outdoors and I had to tear down in the dark...I wish I would have had this thing! It would have lit up the whole area and it doesn't take up hardly any packing space because it's so small. I recommend this 100% for anyone looking for a small light that is durable and BRIGHT!!!!

Disclaimer: I did receive this product at a discounted price in exchange for my honest review. I depend on reviews for EVERY purchase so I figured I would jump in and help out others like me who spend hours researching before actually buying anything. All of my reviews are 100% honest whether I like the product or not. Happy shopping!

Bench tested today. Some of the best 3mm LEDs I've ever bought

I usually don't write Amazon reviews, but I was so blown away by these lights that I figured it was worthy.  First of all, we have 16 6" can lights in our home that were all using 65w bulbs.  Thats 1040w of power when all of them were on.  By replacing them with these LEDs we have reduced that usage to 288w saving 752w of electricity.  Nearly a 3/4 reduction.

As for build quality and ease of install these things are spot on.  Just unscrew your incandescent bulbs, disconnect the 2 springs holding the cans in, screw in the LED pig tail, attach it to the LED housing, and clip the new LED in place.  The clips will pull the light up into the ceiling flush and look much much better than those cheap open bulb incandescent housings.

The LEDs look AMAZING!!  The color is spot on for a home.  The perfect slight yellowish hue, not that blue jewelry store effect.  Makes our home very warm and inviting.  The LEDs don't get quite as dim as out incandescents they replaced, but that's fine.  In exchange they get MUCH brighter when the dimmer is all the way up which has GREATLY improved the usable light in our kitchen.

Overall we are extremely happy with this purchase.  The bulbs aren't cheap, but hopefully in the long run they last longer and pay for themselves in the end.
