4X2Ft 200W LED Grow Lights with 5500K White Spectrum and Over 2.0 PPF/W and 40000 Lumens Great for Retrofit T5 4Ft 8 Lamp Fluo Grow Lights or 400W MH Grow Hood

Switch out all my t5 lights and these are much brighter and with my old t5 lights the bulbs would blow out all the time. I was constantly buying new bulbs. This light no lights have gone on even when my electricity flashes on and off. That would always cause my t5 lights bulbs to blow. So happy I switched to these LED. Didn’t really notice a decrease in my power bill but they raised the rates at same time I purchased theses so I was hard to tell if it lowered my electricity bill

This was a replacement for a T5 version of the same fixture. The led's are extremely bright. A little brighter than the T5 bulbs. My only complaint on this product is the fact that the hangers that come with it are only cheap chain which can only be adjusted so much. I purchased a 4 pack of the corded style of hangers and they work much better.Overall I will give this product a 4 star review.

I have numerous lights and my seedlings do the worst under this one. Spectrum is not right it seems. My high output t5s have produced the healthiest seedlings over several years of observation.

I bought these thinking each bulb was 200 watt but its actually 25W x 8 bulbs = 200 Watts, so they are not quite as bright as I was hoping. Im not sure how they come up with 40k lumens other than maybe each bulb puts out 5k lumens and total is 40K. It doesnt quite work that way though. 25 watts is 25 watts and 5 lumens is 5 lumens. Just because you put them side by side does not make them 8 times stronger. It just lights up more area. Im going to give them a try and pray my baby Desert Roses dont stretch from lack of light. For now I will need to put them literally 6 inches above my seedlings. I compared my 100 Watt LED Bulb next to this light and the bulb is way more brighter. It actually lights up the plants a lot more than all 8 bulbs. The only good thing about it is I dont have to worry about it burning my seedlings whereas my bulb will if its too close. They want that bright white light but dont want to be fried. If nothing else maybe I can buy some stronger bulbs for this. It may be worth asking the seller if they have any. I will update this review after 1 month if my seedlings grow the way they should and give it a better rating. For now 3 stars is all it gets.

Very bright full spectrum lights with almost no heat generated.

Dig em

I haven't even had a whole year and lights have blown out already! Very disappointing

Gave a 4 star, seems to be pretty well built but note it does put off some heat. I received mine with corner crunched in from shipping. It was damaged right where it has a input for plug in
