Hi PD,
Glad to see that chrome series apparently working out for you.
What's your feeling on the coverage of your unit? This is one of the double-lens ('X2-lens') units, correct?
From this picture:
My initial sense is that, since there appears to be a marked, visible difference between the very center illumination and the periphery (moreso than with just a single lens, which will show the dropoff using a light meter, but the visible distinction between zones is not so apparent), the lighting distribution on your unit looks to be more uneven (than with one lens) - i.e. skewed for a small (high-radiance) center coverage, and more marginal at the edge.
Is this accurate, and what's your experience been like?
----
When I looked at the (single module) HGL 21X-Pro, their double lens coverage as stated (roughly a 12" diameter circle, at a height of 12" above the canopy) indicates a usable angle of closer to 30°, and not anywhere near 90. If you've got a miniature, single cola plant, maybe it'd be kind of useful - but if you wanted consistent coverage to the edge, too, it's probably not the light for you.
Plus, one can only grow so much biomass using any level of illumination within a particular area, so creating an uneven coverage like that...doesn't seem very efficient, esp. in something like a ScrOG, which benefits from consistent, even coverage, vs. growing 'trees'. These seem more suited to growing (1-2) taller plants, rather than wide plants or beds/SOG/ScrOG.
This, in addition to the additional refractive losses one would incur from an additional lens, is why I'm not all that keen on trying to further concentrate/attenuate light from the emitters in that manner.
What are your thoughts so far, after having used it (i.e. the 4-module, 15 LED, double lens Apollo)? This is just above the two plants for now, correct? Thx mate!
Cheers,

the light is above two plants but in my cabinet which only has internal measurements of like 16" deep x 30" wide and about 4' tall. all lined with reflective mylar. you can really tell where the core focus of the light is and if i was doing it right and had the funds the 6 spot model would work better for my cabinet but i swap the plants position under the light regularly and the buku is actually tied so its main top is under the light. since i already have one of these i'd jump at the chance to get a 2nd for my set up it would make my day much easier since my plant sizes are so different. penetration on this light is impressive thou buds to the base of my blueberry and nice buds in the center of my buku which is crazy dense.

my main light is about 9 inches above the BB and only about 4 inches above my buku top since its tied under the light. but i've got cfl's hanging to each side of my LED and i adjust those when i rotate the plants to be just a few inches above the plants. since i started growing with Led i try to keep ahead on my Cal/mag so no signs of lacking but i do give it pretty regularlyLookin ridiculous, buddy! Great job! Just wondering, what height have you been running these lights at from canopy? And what kinda nutes are you running? Have you noticed having to feed any extra Ca Mg? Thanks for the help! Happy growing!

so i miss counted before i went back to check my records and my girls are only on day 36 of flowering.
my goal is to get 3oz of the BB and 1.5 or 2oz off the Buku. but this is my first photo grow and only my 2nd grow overall so i dont know what to expect. what do you guys think will be final yield? i'm taking them all the way to 9 weeks or so, depending on trichs.
buku is 31" from the soil
My BB is 25" at tallest point

ya buku is slower to flower and also not know to be a great yielding strain, but she grows very dense nugs of great quality from what i hear..

The blueberry and her pistil packed goodness...
buku still growing but smaller dense nugs, nice smell thou, and her secondary buds are gettin almost as big as her top. last pic shows purple underside of main cola.

at very start of from seed i had cfl's right over the lil ones since my original light died on me and i had to order the bs chrome. the height now is just the best compromise i can make to get decent height over bb and still bend the buku's cola under it until i get my 2nd light in there

I had to put my chrome8s at 2ft above the canopy in order to stop some burning issues in the middle of the plant. Prez is right here, these lights penetrate alot farther than the older bs modesl. My chrome 8s draw 250 watts off the wall and put out 51,000 lux according to Sean @ lighthouse. The will cover a larger area due them needing to be higher above the plants---chrome8 anyhow. And you still get really great penetration. Im hitting 7,000 footcandles on the meter at 4+ feet below the light. At 6 inches outside the housing it drops down to between 5-6000 footcandles. So that why i raised my chromes up higher. Im sure the 4 and 6 spotters just arent as intense as the larger 8. Great job on your ladies!! Keep up the great work. Wonka

i should have better coverage in my cabinet very soon i just ordered California Lightworks SolarFlare LED! should be here in few days! 200w with 5w led and only 9"x9" so my cabinet will have the BS chrome on one side and the solarflare on the other... Think i'll put the solarflare over the buku so it can really get down into its thicker canopy. Thanks to George at CLW! got me a great deal on the light.

what great deal? did you get it for less than $300? that's great news... looking forward to seeing how it performs for you!

oh yeah, i get pic happy when i get new toys so there will be plenty of pics but its going to be 3 or 4 days till it arrives
