Best LED substitute for 150W HPS

I have been searching for the best commercial (not DIY) LED light; Area51, Diamond, Apollo, etc. that would be the closest substitution for a 150W HPS in a small stealth cabinet like the NGB or other cabinet design for 1-2 plants in a SCROG. We are talking about a 2'X2' canopy area.

I checked in grow journals and cabinet design posts, but most are DIY using CFLs and LEDs or a mix. Any 150W cab growers have first hand results when a single commercial LED around 150W equivalent was THE ONLY light used?

I used a BlackStar Chrome 270 for a few years in a cab. It worked good, no complaints. If it were my money I'd go with an Area 51. They just put up a new website. If not an Area 51 then I'd probably go with a Platinum LED. I've seen some great grow journals with those lights. The warranty and return policy are great too.

Thanks, I checked out Area 51 lights and they look good (on paper). I emailed them about the new W100 and they said it would be more than an150HPS, between 175W to 200W HPS equivalent, but not as much as a 250W HPS. At least they seem honest about it and not out to exaggerate their performance.

Get two of them then and you'll be set.

area51 is one of the few commercial companies using decent cree leds. I would avoid the commercial panels using epistar leds, individual or multichip (they're the square "cobs").

Looking at the results of grow journals in the LED section, the best performing model is red+white or pure white... Nobody uses R+B.

Apache also uses quality leds and is a quality product.

I can't afford either, which is why I do DIY with cobs. This cost me about 180 dollars to build including all the parts. (80W actual dissipation) It has an slightly higher efficiency than the area 51. It's designed to be used in low profile setups like stealth cabinets with 120 degree beam spread. (no lenses)

That is an excellent, professional looking DIY! I have been doing some reasearch on COBs and the heatsink is an important matter.

Could you please list the parts of your design and the sources?

I found some interesting information regarding cooling COBs with mineral oil, the LED is submersed in oil, but I dont know how that would affect the light output, if it could be focused, etc.

Check out the Youtube video:

I have a DIY thread and bill of materials here:

https://www.rollitup.org/t/diy-80w-vero-18-ufo-killer.846752/

(one correction in the list of materials, the screws should be 6mm long, not 60mm long)

However, you should check out the other COB DIY threads in the LED section as well for other ideas on how to setup the same thing too. There are dedicated threads for drilling/trapping holes, reflectors, heat sinks, and drivers where builders give good advice on how to ... build, where to get things, and what's handy to have around.

In general, the most accepted design factors are that it use efficient cobs (vero or cree cxa), underdrive lower than test current, use a big ass heatsink.

Thanks Church! There's so many posts here it's hard to search them all accurately. Your design is awesome and a giant heatsink is what I have seen COB makers advocate. I was looking for commerical units to avoid the bare wires, duct tape, etc., but yours is very clean.

Yours has no need for a fan? What are the temps?

I think the mineral oil submerged COB is a great concept and a small fan (like a tiny hard drive fan) can even be submerged in the oil to create cooling circulation. I think the future will bring high wattage non-fan LEDs that run at ambient temps.

It does have wires, it just didn't on that picture. Fan is optional, but recommended. (in case fan breaks, it won't overheat catastrophically) Temps without a fan gets to around 60C, which is safe for the arrays.
