Plugs are no issue, I have 10Plus plugs now which is one reason I am looking to change.
Length X Width X Height for your 120?
I am happy to see some other uv nazis on here like me. When people call 400-430 nm violet diodes "UV" it is like nails on a chalk board. It's like calling the 660 nm red diodes "infrared". Manufacturers only do it because ultraviolet just sounds zippier than violet. Doesn't make it right though. Most modern schools of thought actually believe the whole "UV-A is what causes corals to color up because it's their sunscreen" idea is totally bunk anyway.
UltraViolent ?!? :0)
I plan to change the all the yellow 3500k and a few 7500k whites to either 10k or 14k .. and replace the greens and reds with 420nm. I want an old school power compact 50/50 bulbs look with both the blue side and white side running together. I miss the more purple actinics though.. The blue side turned on by itself gives off a similar effect so I will leave it alone for now... the glow is cool but its just not as cool as the old school purple t12 VHO bulbs. I'm afraid if on the white side of the light I put too much more blue like 20k emitters instead of the 10k it will just be super blue again and I'm not interested in that becuase I can always crank the blue side up to give that effect.
Does my plan seem logical.. am I crazy am I missing anything.
Will removing the optics create more or less shimmer? I would like more spread and less shadows but since running t5s for the last 8-10 years I forgot how much I like the shimmer.
Thanks for the responses/flames/advice.
i have to same plan as you ...with swapping out the 3500k with 10k and reds and greens .with 420 violets.....i got the leds in but just hadnt had time to do it yet...lol...i dont think removing the optics will give you less shimmer...just more spread.....
Here's a reference table:
And little more for those on the "graphic-oriented" side:
:fun4:Now, the research questions for this would be: What are Carotenoids vs Primary Pigments, and Do the multiple absorption peaks indicate a light requirement or an ability to use such for said purpose(s)?
(Hint for newbie2014: 420nm is one of the "needed" frequencies for best growth)
My question would be: is the 420nm needed (for coral growth)? Or is it just for visual appeal?
Great! How long did it take for you to get the replacement LEDs ? eBay? Excited about the shimmer!
