If the best HID LAMPS are 50% efficient then how efficient do your leds need to be to make twice as much light? I used to be an led engineer and I am just saying nobody in the industry is capable of that, nobody. 100% efficiency?
No disrespect intended but there just aren't any Leds out there that can achieve 500w of equivalent light for 250 out of the wall.
This is why standards in the led market are needed. The specs don't even pass the giggle test.
I had a good laugh at the website. From looking at your pics, I will pass. Would need four of them to cover a 4x4 area.See the pictures,... results ... I'm new to LEDs but research first then buy... I'm over 30 yrs growing...NM, CO, DC... research first, do diligence, don't waste time... hehe...

It seems like folks got issues, if u ain't got try ...if not ... talk is cheap... results....I worked for the US Air Force optical devision, weapons labs Albuquerque NM...talk...

Not criticizing you or your skills. Just looking at specs and comparing lighting performance. Your light works for you and that is great. I just like to figure what the real deal is on lighting specs. My pet peeve with all the cannabis markets like lighting, nutrients, hydro systems etc. is all the marketing hype. More than any other consumer market has the most BS associated with the products. It creates a lot of confusion for us gardeners and especially F's over the beginner who ends up spending his or her hard earned money on crap.It seems like folks got issues, if u ain't got try ...if not ... talk is cheap... results....I worked for the US Air Force optical devision, weapons labs Albuquerque NM...talk...

@MidwestToker,And 268 watts from the wall for $ 236 USView attachment 794394 View attachment 794395
That was the cheapo build all 1/16 " aluminum U channel and angle. 1/8" pop riveted together. I had all the wiring already. Just to see how cheap it could be done.@MidwestToker,
What are your build details (I assume this was a DIY build)? Just curious what you used. In looking at all the ways to build a nice light whether quantum, COB's or strip LEDs I see the typical build cost coming down. Seems like $1 per watt is about where we are at right now and you hit that number almost exactly. Nice looking light!

That was the cheapo build all 1/16 " aluminum U channel and angle. 1/8" pop riveted together. I had all the wiring already. Just to see how cheap it could be done.
8-Samsung F-series 3,000k strips $120.00
HLG-240H-24B $ 70.00
U-channel and angle $ 30.00
Dimmer Pot $ 6.00
Power Cord $ 7.00
Misc. $ 3.00
The better builds are costing me about $275-280 with heatsinks and wiring complete.View attachment 794413 View attachment 794414
From the looks of it in the 4x4 I'd say it would do a 3x3. I'm using that light to veg those plants for a side by side right now. Six are going in another 4x4 box I have with a 600 HPS and six will go under my current build of 17 strips with 2-240H drivers. I'm just waiting on a few more part to finish it.So, this is about a 240w fixture according to the specs from digikey but your getting a little bit more out of them. What bloom footprint do you think this configuration is good for?
Thanks,
Dee
CMH right,...I started early 90's MH only 3200k, still would deal with MH than HPS, quality is up...on resins/oils...
