VERY bright and small bulb too  125 watt equivalent

I'm not sure why they don't market this bulb more.  It's really a 125 watt equivalent light bulb at 2000 lumens.  It's the smallest 125 or even 100 watt equivalent you can buy.  It still, HOWEVER, takes a full minute to warm up to full brightness.  It is a VERY bright bulbs.  Most/all CFL lose lumens over their lives.  People should really buy a higher lumen bulb than they need assuming you will lose 15% over the life of the bulb.  I always shoot for 2000 lumens in a bulb which is usually a 27-30watt CFL and would be 125 watt old fashion bulb.

It a good, small high light output bulb.

This is a perfect solution for lamp that only needs a 25 watt (equivalent) bulb.  I had a hard time finding this size.  40 watt (equivalent) is very common but too bright for a bed side table lamp.  The color rendition is very close to the incandescent lamp it replaced.  One of the best features is that a clip-on shade will fit nicely over the glass, something I could not due with a CFL.  At only 4-watts power consumption, this is defiantly a 5-star purchase.

These bulbs are fantastic so far.  I've only had them installed for a few days, but they provide a ton of light at a VERY low wattage.  I use them in my outdoor lamps, so the low wattage is great, since I tend to accidentally leave these lights on for long periods of time.  I'm hoping these last as long as advertised, because they are great little bulbs so far.  The color is true (I prefer soft white), and they are nice and bright.

I bought 4 of these and put them in our nightlights.  They're suppose to use 1/2 watt.  They don't even register on my meter so I think the description of using 0.5 watts must be correct.  They are just as bright as the 7 watt night light bulbs they replaced.  I will buy more when they eventually burn out.

I was looking for a small lamp with bright, warm colors. It is indeed very small, and takes a 25 watt bulb. So, it is perfect as an accent lamp, and the colors are just as warm and bold as advertised.

Nice and bright with good warm color. I have tried this is multiple USB devices from computer to USB battery bank and it works flawlessly. I would say the brightness of this bulb is on par with the 5 watt rating which would make it equivalent to a 40 watt bulb as far as light output. It will no doubt light up a tent or small room with ease and I can't wait to use this in conjunction with a battery bank and foldable solar charger I purchased for camping. I would buy this again!

this unit is very small (just over 1 inch long and 0.5 inch thick) and the mounting tabs are strong enough to accept #6 stainless steel screws.  the unit is very simple to wire. the wiring colors i received were red (constant positive), black (constant ground), and white (measured voltage).  my multimeter reads 4.29 volts and the same power source hooked up to this little voltage panel reads 4.3 volts, so it doesnt get much better than that in a unit this small.  will be back for a few more soon.  by the way, this unit is very bright and draws around 10 milliamps under load.

To small for what I wanted them for but I can get some bulb sockets then use them as dash lights really bright for how small they are

Very nice color at 3000K, no noise when operating, solid construction and bright as rated. I'll report back if anything adverse happens but I'll call this my go to 100 watt equivalent bulb. Do note they are a little taller than a conventional A19 so I guess they are called A21 which means about the size of a traditional 3-way bulb.

This is a big bulb and I knew that going in however, it is not as bright at the 150W LED bulb.

I was amazed at how bright these were since they have a relatively small wattage and are physically smaller than they appear in the pictures.  The motion sensing works well.  It can detect movement at broad angles regardless of the direction the bulb is facing.

I recommend these lights in smaller areas, such as a front porch, hollway, closet and / or utility room.

I've been replacing my decorative incandescent spotlight bulb regularly and wasn't happy that I had to do that a bit too often. So I've been looking for an equivalent LED light that could work with surprisingly no success - they were too big, too tall, too cool, or too dim. When I was offered this product at a deep discount in exchange for my unbiased review, I thought it was worth another shot despite the wrong bulb shape and placed the order. Well, this turned out to be the perfect fit for my little spotlight lamp! It's tough to shop for bulbs online, but this is a small sized bulb about 3" in total length, and just about 2" for the glass bulb portion (width and height). The bulb casts nice warm light, and 40-45w equivalent brightness is just about right for the energy saving 4w bulb with 40,000 hours expected lifespan. My search for the bulb is over, and hopefully I won't need to replace it for a very long time. If you want a smaller bulb that won't stick out of a light housing to blind you, this is it.

This unit was packaged really well.  It was entirely encased in bubble wrap and taped up very tightly.  The light comes on immediately, but it takes a while for it to get to full brightness.  That's okay for my application, but I'm not totally convinced that the full brightness is equivalent to 200 watts.  I have 150 wait equivalent bulbs that seem just as bright.  I would have gone with an LED, but a 200 watt or even a 150 are still very expensive.

This bulb is handy, thu it is just a 5watts, still bright... I compared it to my other bulbs.. Still this bulb is bright... I put this bulb in our bathroom.. This bulb fit in there, not too bright or not too dim.. This bulbs seems would last long...

I got a chance to have it free as a testing in exchange, giving my honest opinion & honest observation...

These are so much brighter than I expected. I replaced three 60W bulbs in my living room and it was too bright. They are more like 100W equivalent. They do a terrific job of lighting up the garage though. No more dark and dingy atmosphere in there at night. I also tried replacing the lights over the mirror in bathroom and I think I had temporary blindness after turning three on only a few feet away from my face. Only use one bulb in there now. If you want bright intense light these are for you. If are looking for something more mellow then get a lower rating one. I have been happier with the 50W equivalents for general indoor use and the 40W for lamps.

These are small bulbs that fit a standard socket. Fairly bright, and great bright white color. I used these in a vanity in a bathroom. I had a single 40 watt LED bulb there (Yes I am a cheap skate.) I replaced the single 40 watt with 2 25 watt bulbs and the output seems to be about the same (to my untrained eye.)

I really enjoy the color of the 5000k bulbs. I have now completed the transition to all LED bulbs in the house. After being cheap and putting a few 3000k bulbs in the hallway, I have found the light. They have been replaced with 5000k bulbs, so the whole house is on the same color pattern. Now, a 2700k or 3000k bulb seems dingy to me.  Everyone has different taste, and to our family these bulbs rock.
