SANSI 200W Equivalent A19 LED Light Bulb, 3000 Lumens 3000K Soft Warm White E26 LED Bulbs, Non-Dimmable Bulb w/Ceramic Technology, 20 Watt Power Energy Saving Light Bulb for Home Office

I don't know if it's really 400W equivalent, but it's the brightest LED bulb I've used. Just one will light up a decent sized room. Be careful of the measurements, it's too big to fit in smaller lamps. It also gets quite hot, too hot to touch after it's been running for a while. Infrared thermometer shows it's reaching 115C in some spots, even in an open / well-ventilated lamp. The color seems accurate to 3000K. Looks similar to light from a halogen bulb, not too pink or green like some LEDs can get. The color rendering is average though, definitely not as good as the high-CRI bulbs I have. As far as I can tell it doesn't flicker at all. Random thing I noticed, the power factor is quite low. 0.45 according to my meter. So while it dissipates 40W of actual power, it draws an amount of current closer to that of a 90W bulb. To be safe I would only use it in something that is meant to handle at least a 100W incandescent.

Bam! Bright! These things are a huge upgrade from any "normal" LED bulbs and they fit right in an A19 (standard) socket. I was afraid these might be slightly too big around to fit in the tight space I had in an overhead fan, but they fit exactly and the light output was AMAZING! No word on longevity yet, because they haven't been in long but so far these don't flicker, they don't got overly hot, and the light output color is right in range. I needed something a bit softer than daylight of 4000K, but didn't want to go all the way to 2700K and these 3000 soft warm came right in if not every so slightly above their target. Yes, these are expensive, but for a 250W equivalent in this package size, I haven't found any better.

Very bright. But not high efficiency as claimed! This 200W bulb uses about 23W like others.

Bought this a few months ago and it’s been so good, love how bright this is and it was easy to install too.

Ordered on October 11th 2025 it’s now march 5 2026 and it’s already burnt out and doesn’t work. Was only used a few hours a day at most. When it was working it throws light in a strange way because of the end cap.

This is a very bright bulb. A single bulb lights up most of my yard, which is exactly what I needed. Fits a standard socket, and uses 40w.

SUPER BRIGHT! If you need to illuminate a dark room.. Here you go.

These are very bright so if that’s the only qualification for purchase, check out now. Design wise, the diodes appear to be mounted directly to the ceramic. Ceramic is an insulator, so these run very very hot after a short time. I used to work for a commercial LED lighting manufacturer and we did everything possible to move heat away from the diodes. Not these. I wouldn’t expect the components to last long, particularly if you run them 8+ hours a day. With our application, the bulbs would be mounted around eye level, peaking out under farmhouse fixtures by the front door and the diodes are scorching your retinas with no diffusion. It’s very unpleasant. If these were offered with a diffused lens or installed behind a frosted glass shade, it’d probably ok.

I'm using this to light my home office. Installed in a ceiling mounted pedant fixture. Very bright, even illumination.

I would suggest caution with this bulb. It may be LED but it does get hot to the touch..If your using it with a lamp shade, allow at least 6 inches on each side. It's a big jump in LED technology when compared to the very first LED. With good ventilation and a safe location,it should last many years.

Game changer! So bright:) I even think I overdid it with a small room but now you can see really well.

Good and bright. Quite heavy compared to cheap LEDs.

Very bright. Lights up my entire 600 square ft garage with one bulb. Highly recommend. Just make sure you have some decent headroom.
