Hi all,
Disclaimer : If you're not interested, please, DON'T PANIC ! don't bother replying, ignore this topic and move out ! it's probably for math "tweakers"
Intro : In my eternal quest for optimal configuration by doing math stoned
I have come to an interesting alternative to the simple CXB3590 CD 3500K option.
Until now, best $$$/efficiency configuration seemed to me as being:
3 x CXB3590 3500K CD powered @49W each by an ELG-150-C (cheaper than HLG on 230V)
with holder and lens ...
According to pct 53% efficiency.
Some Info :
1) 4 CXB3070's 4000/3500K BB @~36W and 1050mA have just about identical efficiency to 3 CXB3590 CD @49W...
but will deliver a couple less W (+- 144 vs 147)
2) Using prices from Jerry@kingbrite : if you include the price of lens and holder: 3 CXB3590 are more expensive than 4 CXB3070
(enough to pay for 2 of see below ...)
While this doesn't really make the 3070's better, it makes them more attractive for supplementing :
I've been looking at supplementing options, deep/hyper red being the obvious target, as it is lacking a bit, and most importantly provides the highest photon flux per PAR W...
After looking at overpriced pcbs with multiple monos, I found these :
http://www.ledrise.com/product_info.php?info=p2605_Osram-Oslon-SSL--High-Power-Hyper-Red-LED--400mW--645nm--Square-PCB-1x1cm.html
Could this be the new best config ? (on 230V) :
- ELG-150-C1050
- 3 CXB3070 BB 4000K
- 3 x Osram oslon Hyper red
Note :
- As according to datasheet, the load being slightly over max V, I expect max current to be closer to 1000mA than the usual 1050mA.
- The hyper reds would provide about 8W out of 150W dissipation, thats : 5.3%.
- HR efficiency looks like it will be maintained at 40% at max current, while that seems low, there is ~18% more photons per par W emited than CXB spectrum, which sort of makes them relatively 47% efficient as far as photons are concerned (sorta)
- Better spread.
Soooooooo... The overall difference in photons is very small, but spectrum is improved quite a bit : with 4000Ks we get more lower blues, less dip after the blues and more 640-660.
Do we need it ?
Is it worth sacrificing a little bit quantity wise for quality ?
Anyone found a better source of deep/hyper red ?
EDIT :Maybe I should add some pictures to make this post more accessible
Any good spectrum generator upto date these days ?
