LED Suggestions

I've grown using T5 for veg and HPS for lowering in the past. I had 2x600w and 1x1000k grow lights, but 1 600w and 1000k were stolen. Now I need another light source for my new grow, so I'm researching and am interested in LED lighting for decreased heat and electricity.

Can some recommend some affordable LED (COB or not) fixtures for a 4x4 grow room? I'm hoping to get something equivalent to 600-1000+ watt HPS. I'm trying to keep it under $300 if possible.

short answer is no. for a 16sq ft space you would be looking at 1000+ for an led setup.

I would recommend trying a 315LEC, but even that is not going to get you the production of a 1000w in a 4x4 space.

There are some cheap 630 LEC fixtures around on eBay which would kill a 4x4, http://www.ebay.com/itm/630W-CMH-Plant-Growth-light-Kits-2-315W-/112250550269?hash=item1a22a777fd:g:~5cAAOSw-0xYYxFL

that's what I would do if I were you.

If you like innovation in led-light I can recommend 300W coolmac / watercooled led light kit
with surprising low price but a bit work in soldering and filling with water. (1h)
It`s made

There are other versions up to 1200W lamp power but for 16sqf I recomend that 300W is enough.
You can use this lamp to produce hot water and the basic coolmac 300W need a watertank
of min. 30L.

Size: 50 x 33 x 4.5cm

Reliable performance: 295 Watt

Heat / power: ~ 160W / corresponds to the heating of 80L water from 16 ° to 36 °

within 11.6 hours. Or with daily use of 12 hrs. a power output of 701 KWh annually.

Chip: 6 x 50 Watt Full Spectrum Chip 380nm-740nm / 33V @ 1.5A

Lumen: 28000-29000LM and very good PAR values.

Driver KSQ: 6 x 50 Watt 1,5A @ 20-39V / IP 66 / PF 97%

6 x optical lens 80-90 ° with reflector and retaining ring

Other materials: aluminum sheets and square tubes, 4 x hose-fitting, 6m hose 12mm,

3 steps underwater pump 2.3 watts, stainless steel screws

brand: lumen-laden

The prices are around 1$ / real watt of lamp power. When you look to the lamp - it`s structure is very simple and easy to understand and with a bit talent and cutting drilling of aluminium you can buy components even cheaper (160$ all components incl.)
For CREE-leds and meanwell-drivers you have to pay a reasonable suplement or deal a special price for the basic coolmac. The owner is very open minded in prices and special wishes of his clients. Don`t forget that it comes from Germany and that you have to pay VAT and custom duties.

I tried this spectrum before and get very satis. for good results and low cost by only
18W / sqfeet while flowering under the table ( 3 feet high only ). Now I will try the same room with this lamp and fix the flat thing close to the top to win height. So I hopefully get the heat out
in summer or bring heat back to the roots during night. There are plenty possibilyties what to do with led-heated water - not only in growrooms - and specialy now in winter

You can build a cob led for a 4x4 for about $500 each that will out perform a 1000 de
here is how 9 citizen clu-048 1818 3000k $22 each
3 driver's elg-340-54-d2 $50 each
12 heatsinks cob holders and reflectors $15
Now all you need is 3/4 aluminum and wire $30 max
