GEHL LED or Houyi LED lights ?

Hi guys, I have gotten great results from the GEHL 720w (240x3) reflector type. Actual draw is 480w and it covers my 4x3 space perfectly. Right now i'm about 1'-2' from the canopy. I think the price is around $450. I think they make smaller panels also.

My Journal is on another site but I'll give you the rundown. This is my 3rd grow with this lamp.

Good to know... but, the deed is done.
Well going to see what it can do. Cost was like 130 something.
I will post my findings an Pic's.

I can understand your hostility with Chinese manufactures. I have dealt with them directly during 2004 - 2009. I have been to China many times to purchasing products that are unrelated. I could tell you tales about that place, sketchy companies, good and bad. :peace:

OK, the light came in from Houyi. Installed over my current experimental grow. Kind of late since, they have been in flower little over a month. So, don't expect much in results. From what info I have gathered. The advertised Wattage is less. So, the new 150w is 100w and the 4 mini 75w are 50w each. Totaling 300 watts for my flower area. Good enough for what i need to do and keeping in compliance with my States MMJ Law and plant restrictions.

Will make a journal on the next grow. We will see how it goes.

AC vs DC LED lights. I remember being surprised about how much heat a AC LED lamp puts out. If you compare DC LED lumens heat output along with price etc...why go with AC? I put up a tape LED 24 volt, 16 foot tape, at $86 putting out 3300 lumens connected to a 24 volt adapter (84w flextec $37) ...both from 1000 bulbs, installed this in a dining room as part of a subcontracting job. Very surprised by the light output and the great thing is that you can set up whatever layout you want. I have a $3.00 LED at harborfreight that would be great for seedlings if not for the rapid draw down on the 3 AAA batteries. With a fresh charge on the batteries the $3.00 DC puts out more lumens than a $15 LED AC bulb that has to have its own heat sink.
 
there r leds driven by AC? you mean leds with integrated dc Driver? So then ultemately there is no difference...except maybe that Driver + led r put together in a tight space...and both produce heat
 
No, he means AC LED's. Iirc, they have a rectifying circuit which keeps current over the LED flowing in one direction. However, because half of the AC current is going backwards it closes the gate and the LED turns off briefly. For this reason AC LED's will strobe at half the frequency of the AC (usually 50/60Htz in US).
 
Ok..I'm back with some pictures. Here is how this light is doing. It's a Houyi 150w.. But, really 100 watts.
Added 2- 50w mini's to the side of this unit to pick up the outer edge of the grow.
I think the 100w unit is doing nicely.

It's been a while. The 720w (240x3) GEHl reflector works wonderfully. I have upgraded to the GEHL 1200w (240x5w) with a 13 band spectrum. Actual Draw is around 640w. Hopefully it works just a well.

Here are more pictures from my 720w (240x3w) Reflector

This should help in regards to a spec sheet/s from Gehl.
Using Noah 8, Love it!
