Is this the Cheapest led grow light?

£140 or 3/4 of an Ounce in these parts for a 720 Watt led grow light.
Where would you get it.

It should be ok for a 4ft x 4ft area. 1.2m x 1.2m
6 bars
2508 diodes
2488 white
20 reds

Driver is a 600 Watt digital HPS ballast with 660 watt, 600 Watt, 400 Watt and 250 watt setting.
660 Watt setting = 715 watts on kilowatt meter.
600 Watt setting = 661 watts on kilowatt meter
400 Watt setting = 508 watts on kilowatt meter
250 Watt setting = 344 watts on kilowatt meter


4000K whites with 660nm reds.
I took a couple of par readings in a non reflective open space at 12" - 300mm away directly under the fixture.
Big numbers are at 660 Watt setting on ballast
Small numbers are at 250 Watt setting on ballast

As for efficiency, not sure. They say With a PPF of 1800 μmol/s and a fixture efficiency of 2.5 μmol/J
Only time will tell if it blows up! lol

I also tried it with a 250 Watt digital HPS ballast. It reads 271 watts.
Centrer reading was 500 on apogee par meter at 1ft - 300mm away.

Enjoy!

I put my mate onto those a while back.
He's got two.
Technically I put him onto something similar and he found those and bought them.


Barmey prices.

Well they will definitely grow some buds.
It'll be interesting to see how long they last.

Any updates on your mate's lights?
Ìm gonna set mine up in a couple weeks in the hut when i harvest the plants in there.
I'm taking down the Big FOTOP boards from Meiju, probably mòve them to 4 x 4 or use as side lighting in hut..
They've served me very well for over six years now.
They cost an "O" for 2 boards....... £200. Buy cheap, buy twice........ my arse! Lol
Cheap as chips!
