Over the years (~4 so far) I have been keeping nano reef tanks lighting has always been a bit mysterious.
Was watching some videos and looked up Radion lights. They call their lights the best lights in the world. It seems they have a newer one now, G4 and there is one main factor which looks like it makes this a home run. It appears to me the advantage is the new style cover for the LED
bulb called hemispherical edge.
This is just one type, there are a number of others which value themselves the cream of the crop.
What I really wanted to discuss and compare is actually the LED
lights part of these fixtures. Not their other ultra cool features.
If you scroll down on the above link, it shows the pattern of the colors of lights and specifically names each LED
LEDs 2 sets of these usually
4 - Cool White
4 - Deep Blue
4 - Blue
2 - Green
2 - Photo Red
4 - UV
2 - Violet
1 - Warm White
The Par 38 45W bulb has these for $20.99 You would need 2 of these bulbs to somewhat compare to the above
Marine: (Reef A is out of stock the one with the green led
too so couldn't compare it)
5x450nm blue violet /deep blue
2x410nm, violet purple
Mine has 54W
7 blues but I can't really tell how many of deep or regular
7 white total - 1 or 2 warm white and the rest cool white
For growing corals I know plenty of Reefers use the knock offs/China lights
So these light colors and bulbs are very similar, would be better comparison if I had the numbers for the light I have, it is slightly different.
Any way what are peoples thoughts about the actual light colors and intensity.
Realizing there are fancy upgrades with the high cost lights, like light type and duration - Those things can't compare to a PAR 38 bulb.
What do people like /or use and if you used the budget ones in the past did you upgrade as fast as you could and why, and only use for DT or use only the high end lights on all tanks, etc.?
