I figured the Cephs needed some mood lighting so I wired up two new bars to run some longer term testing on the Moonlight kits. I only have 2 little ones ready shto go in right now but more will be added as they come out of the nursery. Overall I've been really impressed with the results from the moonlight kits considering the power usage. I should have an actual wattage meter in the next week or two so I can confirm they are using the power they state they are.
One note, while making these two bars the Philips lenses were a joy to work with compaired to the others. Too bad they won't fit on the white LEDs.
The two bars are as follows:
CW WW RB DR
WW CW DR RB
Cool White - 5,000-8,300K Color Temperature
Warm White - 2,600-3,700K Color Temperature
Royal Blue - 440-460nm dominant/peak wavelength
Deep Red - 650-670nm dominant/peak wavelength
The CW/WW should have the highest output in the 660nm/430nm ranges with some filler while the RB/DR have more output in those ranges and nothing else really. The middle area should offer some mixing from both, it should be enough to give me a general direction where to go in the future.
This bar is only running at 350mA/13V so its a lot less power than the other 2 bars, with my result here
http://www.terraforums.com/forums/s...le-Short-Term-LED-Experiment-with-a-few-Cephs I wanted to set something up for atleast a year and see how things go. I have some concern that the main 2 bars may be too much light for my goals.

Reference photos of the two draftees, bad photos but they will do the job.

I've also started a 6 Ceph manual flood system test to see if a flood watering system is practical. Really basic I flood them once a week and syphon out all the water after about an hour. I'm planning on storing the flood water for reuse and will aerate and test the TDS before each flood cycle.
