Wow. First fixture I've seen that spaces the bars correctly for the best ppfd. Very very cool.Thanks guys, I didn't realise it was an app link

Hope this one works. There's vids on YouTube too, not many but a couple showing its design and par map.
I was ready to order their qb lights but when this was released I opted for it, I like the average ppfd concept. My grow is around 2m x 2m so I'm hoping that 2 of these would give coverage of most of it, leaving an edge, to use as an area to store bucket and place fans etc.
If they are as powerful as they suggest then I think it will be overkill, but rather have the extra power incase my set up changes in the future.
I noticed that as well, geeklight has always had nice tweeks to their lights. Their app controlled led channels are cool. Being able to set UV, 660 and/or 730nm for certain on/off time’s. Pretty swanky.Wow. First fixture I've seen that spaces the bars correctly for the best ppfd. Very very cool.
The concept of a light with that even cover is very interesting and the design looks promising with spacing tweeked but id prefer to see those numbers measured before believing in them, not cause they are too high, but they are too even. Spacing of bars can help you even out over one dimension (side to side or front too back) but not the other one, unless you have some asymmetric power levels or diode densities. Even with a reflective tent (which isnt iiindicated in the par maps but lets assume) i find it hard to believe in a corner reading with only 3% less than the middle. That is very hard to achieve, trust me ive tried and it is litterally impossible with a linear build with homogeneous diode density and equal powerlevels all thru the strip. I call at least partial bullshit on those numbers evenness. And geeklight is not really a company ive seen properly tested by anyone. Then again, the light might fine and have better evenness than anyone elses light, but when they are fairly clearly fudging on one thing then where does the fudging stop?Thanks guys, I didn't realise it was an app link

I agree, the corner reading's are suspect... meaning the rest are questionable as well.The concept of a light with that even cover is very interesting and the design looks promising with spacing tweeked but id prefer to see those numbers measured before believing in them, not cause they are too high, but they are too even.

Please see if you can confirm those numbers, or atleast the evenness?
I have the same one's coming in. They look excellent!Can I ask for the link where you ordered this?
Wrong one homie. You want the MJ-650 8 bar.Hey everyone, I got quoted a price of $760 including shipping but with an additional 2.95% credit card fee for the light below. In your opinion is it worth it? This is the style of light I like and don’t want to do much DIY-ing.

Yea. If you look at the par map for their 320w it looks pretty rosy.I agree, the corner reading's are suspect... meaning the rest are questionable as well.
I'll certainly try mate, would a cheap light meter be good for that? I can get one of those for a tenner and I assume it would show difference in the relative brightness across the fixture I hopeThe concept of a light with that even cover is very interesting and the design looks promising with spacing tweeked but id prefer to see those numbers measured before believing in them, not cause they are too high, but they are too even.

The fixture wouldn't fit through the access hatch, it is real small, so needs to be assembled in the room itself. Even a hg550 style panel wouldn't fit as the hatch is that smallWrong one homie. You want the MJ-650 8 bar.
Get the lm301b.. cheaper.
Yes, for getting your an idea of even spread a lux meter is ok. Its a good thing to have but dont go and buy all account on me, but i do like that youre prepared to put knowledge back into this thread/community.I'll certainly try mate, would a cheap light meter be good for that?

They’re not the same they’re just the same footprint same everything but the H version has a different phosphorus coding which produces a different spectrum more tailored toward the red and the 2700 and 3000 K Calvin just like 4000 5000 Calvin the phosphorus coding on those helps balance everything out to reduce the blue spike and higher Calvin LEDs to prevent plant Stunt and smaller compact from too much blue an increase is more red and the higher Calvin to equal it out I am just the opposite with the lower Calvin it hasSo Ezy basically affecting the blue to red ratio to help promote better growth from plantsJesus when will people understand 301b and 301h are the fucking same.

The one posted LM301H is that the one that’s not marked as the LM301V now look at the 3000 Kelvin and tell me that the LM301H doesn’t have as high as a blue spike as the otherWrong
