Many people complain that these don't seem very bright. Just remember it's the micromoles, not the lumens, that matter. Each bulb emits 1900 micromoles. 1 micromole is equivalent to 602 quadrillion photons. I use these outdoors and when elevated properly they cover some ground. 4 houses away they're just as bright to look at than in my own yard.All of my flowers have responded much better to these than the white LED grow lights. At 150w equivalence these use just 12 watts each. Many of the 100w equivalent grow lights use 15 watts. So these use less energy and produce more usable light than what many others offer.I don't know of another grow light of this capacity for just $25 a pair ($12.50 each). Try them and see if your plants agree this is a good product.

i wasn't sure about these bulbs so i ordered a couple of them. yeah, they work. my plants like them. i had the intention of buying more if these worked but when you consider factors like cost, life span, and dollars per watt, i was suspicious and thought i could do better so i bought some two of the FeCiDA LED lights here on amazon. Though rated at 50w i thought the FeCIDA lights would blow away these 12watt lights. To my surprise these spotlights are visibly brighter than the FeCIDA lights. I find this odd. I guess i like these lights more than i thought initially.

Pros - Being able to purchase 250 watts of grow lights for this price is hard to beat. The majority of the exterior is plastic, so they don't break as easy as CFLs.Con - They're not super dim, but they're definitely not the brightest grow bulb I've purchased.

So far so good. Keeping inside plants alive during the long winter for a novice. Very bright, I suppose energy is efficient. 3 star on price just because it could always be better. Over all 5/5.

I think they work just fine but compared to my 90 watt LED pair these don't seem as bright. Still not mad at the value. My succulents still love them.

Great light by plants really love it. It's just a little heavy so it makes my light fixtures sag a bit.

The bulbs arrived in a timely manner. So far the one I've put on is working great. I use it for all the plants I brought in from outside and it doesn't emit any heat which is a plus.

Said they were 150 watt bulbs when they are really 100 watt bulbs. They show a picture of a box with a 150 watts on it and when you get them they say they are only 100 Watts on the box.
