hydrofarm grow lights, ballast, reflector

I currently have a 4sq ft grow tent with 2 90w ufo's and 1 blackstar 180w led flower panel. My plants were happy and doing well but nothing extraordinary. I added this light to the mix and now all my plants are exploding with tons of flowers. At 290 watts of actual led output my plants were happy now at 475 watts of led output I have hit the sweet spot and they're producing greater results then MH, sodium or t-5's have ever done for me. I've been experimenting with led lights for a while and from what I've learned so far is, you must use at least 1 watt per light. Using multiple 90 watt to 240 watt led lights is better than using 1 huge 600 watt led. You get a larger sweet spot. 90 watt led's are good for 2sq feet only. the 240 watt lights are good for 3' by 2', no more. 2' x 2' is better. And most importantly the height of your LED's play the biggest role. I keep the LED's 2 feet above the plants if I want them to stretch a bit and 12 to 16 inches if I want them to get bushier. I...

I bought mine about 2 months ago so my usage has been limited to veg growth for delicate indoor plants, but man... my plants are REALLY happy with this light. I'm pretty careful with my plants in general, but I've never seen such vibrant, uniform, and healthy green color in their foliage before. The light does put out some heat, pretty much the same if you put your hand to the exhaust on your computer, but I'm sure it's partly because my setup is inside a 2'x3' tent with an intake fan but no exhaust fan. It generally keeps the tent about 5 degrees higher than outside the tent but it's def tolerable for the plants. Pay attention to the height (10"-14" from the canopy) for max effectiveness. Can't wait for flowering because thats supposed to be the light's strong suit with all the red leds. Don't think twice, get this one!

Update: Last night half the LED array went out. I called Lighthouse today and an actual person picked up the phone after two rings and listened to... Read more

I was blinded when i first turned this on, but I did leave it face up next to me when this happened. There's a white led, a uv(invisible) one, six blues and 72 reds (half 660 half 630). They use a picture for the three band light when there are six bands of light(band=color). Plants will definitely thrive under it. Garden plants would do well 1 1/2-3' underneath depending on how you wanna stretch them. Use it like a 400w hps except it has no problem with heat. It seems to be a good flowering light, and a great vegetative! Definitely a great deal next to same priced 90 watt grow lights. I never got how 90/120/180 watt led's would be above $200 when this extremely powerful light is only 270!

Led's are definitely more energy efficient using only 1/2 wattage for typical growing (only $15 for two months of 12/12 cycle) and last 10x longer than 400 watt HID lights for the same grow.

PS since plants are green they absorb red and blue light. thats how you get that... Read more
