SANSI 250W Equivalent A21 LED Light Bulb, 4000 Lumens Dimmable LED Bulb with Ceramic Technology, 3000K Soft Warm E26 Base, 25,000-Hour Lifetime, Efficient Safe, 27W Power Energy Saving for Home Garage

Picture shows from left to right: 100w equivalent CFL->100w equivalent Philips LED->27w dimmable version of this LED->17W version-> halogen/normal size bulb.I purchased the 17w and 27w 3000K versions. Let me start with the 1 negative comment and one neutral comment: the light distribution is better than average, but not perfect. It's not omnidirectional like old incandescent bulbs, but its better than other high output LED bulbs I've used.The bulb dims well, but some people may not like that the color remains consistent, it doesn't get warmer/yellow like incandescents do.Now the good! Its bright and its compact! If you want to replace a 100-150w bulb, the 17w one works great. Its actually the size of a old lightbulb. They stay cool, except for the ceramic heat sink, which is fairly tucked away, but you still can accidentally touch it if you aren't paying attention, see pictures.The 3000K color is perfect in the house. It's just plain, normal white; not too blue, not too yellow.

A19 LED bulb, 2500 lumens, color temperature 3000 - no one else offers all characteristics in a single LED bulb. Before this, if you wanted 2500 lumens, you had to suffer an oversized A21 bulb, which is too big to fit many fixtures (including those in my own house.) Unlike those, this A19 sized bulb fits in any fixture that takes a regular bulb.These fit perfectly into a very old ceiling fixture and dim without any buzzing sound and throw plenty of light. I immediately ordered more.It looks more like a UFO than a bulb that Thomas Edison would recognize, but I consider that a major advantage.The drawbacks are its high price, and a less-than-a-second lag after flipping the switch before it fully illuminates.

Day 1 (yesterday) I put it in a dimmable fixture on the porch, just to make sure it worked. It did. Very bright!Day 2 I got up on the ladder to install it in the yard light fixture it was intended for and it caught fire. I could smell it burning.The seller responded to my review below. Eventually they responded to me in email. This is what they said: Dear Amazon Customer, Our bulb is safe and it will not catch fire normally. If it is used in enclosed fixtures or used with a voltage which is higher than 120v, it will be dangerous. So just use the bulb correctly, it is safe enough. Best, SANSI TEAMObviously, it DID catch fire, being used normally and the fixture was not enclosed, and was a normal 120v fixture. No apology for their faulty product or nearly burning my house down. If it were safe enough it would not have caught fire. If it were possible to give negative stars, I would. I am reporting this product to the US Consumer Product Safety Commission. This review was supposedly hidden by the sensitivity team. If y'all are too sensitive to understand a fire hazard, you are probably too sensitive to use electricity.

I bought this bulb to replace a dimmable 27 watt LED bulb which was supposed to produce the equivalent of 100 watts of light. Since the motion-activated exterior light has a yellowish shade, the light was never very bright. On the dim (non-activated) setting, it barely produced enough light to see beyond the doorway.This bulb is easily three times brighter, and produces a bright white illumination which is perfect for this security light. The pictures of how bright it gets don't do it justice, but you can see there's a lot of illumination there. In fact, when activated, it's bright enough to see the end of our 120 ft driveway. You could definitely see if there's anyone there.Highly recommended.

This bulb C21BB-XE26-17W has "Forbidden to be used in enclosed luminaires" printed on the bulb frame. It sure would be nice to have this information made abundantly clear before purchasing. This message is directed at Amazon as well as Sansi.The product description says "wide applications" and "durable and reliable" but nowhere does it say not for enclosed fixtures, which probably account for at least 50% of the fixtures. I should not have to pay for return shipping!

I have been purchasing LED bulbs since LED bulbs started and I have met many bad apples. This new bulb from Sansi is the best LED I have ever purchased! In two rooms I need extra bright task lighting (I am getting older) and this 150W equivalent fits the bill. It is quiet! It dims great! It is bright! The color is excellent for detailed tasks.As my other LED bulbs burn up the circuitry (bad design on other bulbs; which Sansi has addressed) I will get these: B07NZ37B24, the 100W equivalent.At my age, I use 100W equivalent, Dimmable, 5000K bulbs throughout my house. I use Lutron Caseta Smart Switches to set the dimming in each room to suit my needs. In two rooms, I will use 150W Sansi bulbs for were I need excellent, full bright lights for detailed tasks. But at night, 1-20% bright is perfect for me.This 150W Equivalent LED Bulb performs beautifully at 1% as it does at 100%. No buzz!If budget is important, ECOSmart LED 5000K Dimmable [B07964LLF5] from Amazon or HomeDepot works fine, but they eventually die because the circuitry gets cooked.When it comes to Dimmable Bulbs, I go for the High Color K Value and the High Wattage.When I need the light, it is there, when I do not, Dimming is excellent.Alexa, set Stella to 10%.Hey Google, set Raymond and Gilbert to 20%.I use over 30 LED bulbs in my home and over 20 smart switches.

These just came to my door today and I immediately installed them in the garage (which you can see is a mess). I bought these to avoid adding more lights to the garage, hoping that by simply replacing the existing 2 bulbs with brighter ones would be an effective and easier fix. I was right.Huge improvement over the standard LED bulbs I had in there before. Pictures don't quite do it justice, the difference is more substantial in person. Very pleasedThese are the only high output led bulbs I've purchased so I can't compare them to others on the market but I can tell you they are far brighter than a standard led bulbAs I said I just installed them today so I can't speak for the longevity of these bulbs, but if something goes wrong I'll be sure to update my reviewUPDATE-MARCH 7, 2020:Still working great, went through -40°C weather no problem. Turns on instantly at full brightness no delay. Very happy with the purchase. Will update if any issues arise.

When I first bought these 2 for the bathroom I noticed the light was too white, burning 5000K white for the eyes, even dimmed was hard to look. I ordered the 3000K white set after, the difference is big. The only drawback of the 3000K is that they are not dimmable. Hmmm... The construction is identical so I took the dimmable base from the 5000k ones and moved to the 3000K LED hemisphere. In the picture you can see the 3000K are dimmable now compared to the modified 5000K with no more dim feature.

Il manquait d'éclairage dans mon garage. J'ai changé les ampoules ordinaires pour ces ampoules. Ça éclaire très bien maintenant et c'est beaucoup plus beau. J'ai pris le modèle dimmable qui fonctionne bien toutes les intensités. Il n'y a pas de scintillement. Elles sont parfaites avec les dimmer Lutron qui fonctionnent avec Alexa. Je pensais qu'il y avait seulement 1 ampoule pour ce prix car le mot ampoule était au singulier. C'était aussi marqué: quantité 1. Il y a avait 2 sur une des photos et il y en avait effectivement 2 dans la boîte. C'est un bon prix pour 2 ampoules DEL de cette qualité. Merci,

Bought these as part of a streaming setup. These were installed in Ikea Tertial Work Lamps, with Newwar soft diffusion covers over them. The result is a very bright even white light that takes up minimal space, and provides excellent lighting for subject or green screen. When used on a person, I've kept the brightness pretty minimal with a Lutron Dimmer, indicating that at least in my minimally controlled environment, this wattage may not be necessary. The green screen filtering results are certainly better closer to full brightness, but the length of time someone could tolerate these pointed at their face, even diffused is questionable. Maybe with larger soft boxes, or for shorter sessions. Also, if you are planning green screen dedicated lights, these would be perfect.These are slightly larger than a standard bulb, so keep the dimensions in mind when planning your purchase.The cost is a little high, but it's a unique product without significant competition. It also delivers on its promises. I would happily recommend.

Product does not work in a regular Canadian 120V outlet. Dimmer or not...wouldn't work. ZERO customer service. Wrote asking for assistance ('cause you know...screwing in a light bulb is super complex!) and received no reply from seller. Amazon "tech" walked me through how to screw in a light bulb...ROFLMAO...I'm serious! Refund provided by Amazon.
