I will be using that one if I got my tank bigger than what I use now. But for now, I am using an ordinary light but I plan to replace it by a led light bulb. My friend explained to me that these lights consume less electricity than the other light bulbs.
Well this is my first time to read an LED light bulb can grow algae. I am using in growing the algae is the old steps but now there are modern LED scrubber light to algae. Now I decided to change my old light bulb in my tank in much good result I will replace a LED light bulb so my algae can grow regularly.
Remember that LED's are for experimenting only... do not use them if you must have filtering that works.

Cree Launches Highest-Performance Warm & Neutral White Lighting-Class LED

I order some neutral and some warm to see how well they work.
Hope this helps.
Is anyone making a power led-wall, with high power and consistent intensity across a large surface? I've seen low power walls for signage backlighting, but nothing meant to project high power.
Just finalising scrubber design now, it's currently planned to have panels of LEDs attached to the wall the tank sits on top of (it's a 220g in-wall tank) to light a single sided vertical scrubber (75cm * 40cm).
Will certainly let you know how it goes.
I talked to my regional Cree rep about XM-Ls vs XP-Gs. XM-Ls just might be too intense. You would have to diffuse them so much that it might just make more sense to get a couple XP-Gs and diffuse them only a little.
The micro-diamond diffusion grating from Lowes/Home depot works great for diffusing LEDs.
Basically, it is an acrylic sheet, with little pointy diamond shapes on one side.
If memory serves, about $10 for a 2' x 4' sheet.
Put it about half way in between LEDs and screen.
It scatters light well, with fairly low loss.
I do not see any point source issues on my scrubber after using it.
Since it is flat on one side, you can easily glue two together if you want.

Interesting about the new XP-G warm whites.
Although not sure it really makes much difference. From my experimenting, key is to have lots of red.
My best results (although limited not-very-scientific testing) was 2 x red + 1 x blue + 1 x warm white.

Just something someone might want to try out.
light coverage is rather square which would be good for our purposes
and mounting system is easy to use/update (watch video)
Notice also the custom spectra choices and the high IP rating

As far as that make I have no experience.
Hope this helps.
Just curious-how are the LED scrubbers doing these days?
