Bright and Long Lasting, Will Buy Again

K RuggsFebruary 11, 2026✓ Verified purchase

Love these lights. Energy saver. I have used them in three barns, 16' tall trusses and they work great. Had them installed previously for several years with no issues. I'm a returning customer! Read more

Sansi is the best!

Tucker MacFebruary 13, 2026✓ Verified purchase

These Sansi bulbs with an E26 base are amazing. I’ve used them for various applications for 5 years and they are reliable, and REALLY bright. You can really increase your light without adding fixtures. For example, my wife wanted a hanging light in a room with a lot of light. I got a big shade and put a 150w (actual, not “150w equivalent) foldable 7 panel light. Advertised as 20,000 lumens. It was disappointing. I replaced it with this little 35w bulb, and it was a lot brighter. Sansi is fantastic. I’ve used a lot of their bulbs and they last forever and put out gobs of lumens. Yes, they are not cheap—but they are worth it. Read more

Perfect bulbs. Work great and very bright in

BamacabFebruary 11, 2026✓ Verified purchase

Wonderfully bright lights. I keep buying more. Little expensive but I can’t caught the manufacturer. I’m hoping they keep lasting. Read more

Almost too bright

Keon B. BillingsFebruary 6, 2026✓ Verified purchase

This thing is ridiculously bright. Exactly what I wanted. The size is a little bigger than most, but that is to be expected. I can’t speak about durability yet because I’ve only just got this thing, but based off the reviews, it seems like it might do for the long haul. There is no humming there’s no buzzing. It’s just a quiet performer Read more

Nice and Bright

Dana LeeDecember 15, 2025✓ Verified purchase

Turned my garages dark side to the light side. Just what I wanted. Warning: Do not look directly at one, you will see it for a long time after no matter where you turn. Read more

Great bulbs, premium pricing

Multi MillionaireJanuary 13, 2026✓ Verified purchase

Fantastic bulbs! Great build quality, good light output, 5000 lumen in an A-19 size! Will update if they die too quick. The ceramic heatsink with “air vents” keep it surprisingly cool for 5000 lumen bulb! But, they’re at a premium price, should be $~16 for the 2 bulbs. Read more

Outstanding Customer Support & Impressively Bright Bulbs

riode manuel desariDecember 24, 2025✓ Verified purchase

I initially had an issue where one of the bulbs was defective, but the seller's customer service was excellent. They quickly sent out a replacement and even refunded my original purchase. The bulbs are incredibly powerful—while I don't have the tools to measure the exact light density, they are visibly much brighter than standard bulbs. I’m very impressed with both the product and the support. Read more

Good buy

Ronald H.December 7, 2025✓ Verified purchase

The daylight bulb is super bright, but it costs more than incandescent lights; however, the brightness, longevity, and design of these bulbs are worth it. Read more
