100w Clu048 led Grow Light pin Heat Sink meanwell Driver with 90 Degree Lens Full Spectrum Cree LED Grow Light Bulb for Indoor Plants Vegetables, Flowers, Seedlings, Greenhouse, Hydroponics

this are 54 watts not 100. work great for veg. Switch too 100 watts for flower.

100w Clu048 led Grow LightThe footprint is not 2'x2' maybe 1.5'x1.5'. I measured the light with a cheesy meter so I won't list lm values. I compared it to other lights I have (quantum board and and viparspectra dimmable par 450) and the 100w Clu048 led Grow Light is last. At $112 for a little over square foot that's not very competitive.The build is high quality with top of the line components the citizen chip looks to rival the Cree. So it is competitive with other cobs in its class.I will update after a grow. Hoping for good results after spending $$$$****UpdateThey do work awesome 6 in a 2x4 tent gave pro results. better then the viparspectra and on par with hlg.

Fantastic product, powerful, excellent communication. Great price...Have purchased three of these. And will be ordering more

This light came to me and did not work. I had to wait over the regular said shipment time to recieve it, just to be disappointed.

Love the white light and the spectrum of the new chips but got a1800 for about the same price as this 100. If you need a weak light to enhance the spectrum of the blue/red older models this is a good choice. Doesn't have an on/off switch. One Good point is the passive heat sink.

Great light just doesn't have good penetration. Plants still like it gets the job done

This is a decent light comparable to the 54w Optic -1, NOT the 100w Optic-1XL. It's disingenuous to call this a 100w light when the driver can only put out half of the watts. It's fine as long as you know what you are buying: A 50-60w light.

I always wondered about this product. Not to bad. I wish I would have used the money for a different product but not bad if another diode led is used with it.
