Apache AT600 led vs 1000w HPS Blue Dream Grow

I'm looking to cover each tree with 4 lights. I'm thinking either a51 r/w or onyx bloom. The onyx will probably be a little cheaper but the a51 might be more efficient. The onyx would run 1000 watts per but would definitely light them up. The spectrum looks nice on those leds. A51 told me he will have the spectrum charts on his new website in a week or so.

Right now, there is almost nothing in the way of details on their site. Someone said Yoda from star wars works there. Those Onyx look like the low end lights you can order from China.

I got my numbers from DigiKey, supposedly sourced from Cree itself. These were for 2700K warm white CXA2050 (I think, feel free to correct me). The higher K numbers (5000K, 6500K,etc) were better, but I think 2700K is a better spectrum.

The Cree CXA's have improved drastically, my 3070 Z4 3000k's are at 1.4a and if I dropped them to .7a they would get 150lm/w at 46% efficient and mine are not the best ones out now.

The main factor holding LEDs back is their high costs. Those COBs aren't very efficient. A one watt diode puts out more than twice the light per watt as any COB. 1W diode=236 lumen/watt.......50W Cree COB=86lumen/watt They're just a lot easier for a do-it-yourselfer to build.

1W LEDs are no longer in the running, the most efficient small LEDs available to us are "10W" the Cree XML2 and the Vero 10 (a small COB). The highest XML2 bin currently available in warm white is T4 and it creates 126 lumen/W running at 25% power. The Vero 10 3000K creates 125 lumens/W at 25% power.

As for COBs, the highest CXA3070 3000K bin currently available is Z2. It creates 140lumens/W at 25% power cost about the same/ PAR W as the XML2 and Vero10.

The the CXA3070 top bins GG and I were lucky enough to score when they were available, create 161 lumens/W at 20% power and cost 20% less than the others mentioned.

There are no LEDs that can reach 236lm/W. The closest we can get is with the Cree CXA3590 5000K CD bin running at 300mA (13% power), about 197lumens/W. Speaking of those, thnx to a RIUpper I will be installing one tonight to test for vegging use

I would think that onyx are sourcing their cases from china. If you look they will sell you the case for diy. Unless they are flat out false advertising then the lights should be pretty good. Cree xml2 are pretty nice.
 
I have a Grow Onyx, it's a well built light. Their mounting system is kinda weird, hard to explain, but it works. It requires a pair of screws, so in a tent you might need to run a 2"x4" or something to fully utilize their mounting.

Troll? Look at the site yourself. There's very little detail at all. And Cidly was selling an identical light to the Onyx as their CHEAPEST light before I ever heard of Onyx. Are you that thin-skinned?

Link please,I don't believe Cidly makes anything with Cree XM-L2's and Meanwell power supplies.

What about vertically hanging them?

Well, you could just use one side of the mounting I suppose, not sure if that would be ideal though. Maybe I'll try it for a minute and report back. If the existing mounting is not ideal for vertical setup, I'm sure you could drill your own somewhere, like the heatsink.

It doesn't have a case so to speak,the heatsink has a top and bottom cover, I'm 24 days into flower with one

I am with Cap, please link us to the 236lm/W. I dare say it doesnt exist in the retail market. If it does then you just changed the world of growing for all of us :)

I thought I read that Cree broke 300lm/w in the lab but you can't buy anything over 200lm/w now.
