Hey all,
after playing around with some LED fixtures above the fragtanks for quite a while, I decided to use this lightbulb change cycle, to reduce the amount of small bulbs, using LED instead. A small, 24Watt T5 costs nearly as much as a 54Watt one, so bulb-cost per Watt is really bad with the small ones.
LED should last for several years, not the %&ยง# 6 months for the blueish T5s.
The bulbs on the pic have already been changed in this cycle, the LED are the new “to be changed next week” ones.
The bulbs on the pic are:
4 with 4*54 Watts [2*AquaScience blue / 1*AquaScience special / 1*Giesemann Aquapink]
1 with 4*24 Watts [2*AquaScience blue / 1*AquaScience special / 1*Giesemann Aquapink]
4 MH (HQI) 400 Watts [2*Giesemann Megachrome coral / 2*Giesemann Megachrome marine]
4 LED spots max. 90 Watts [Kessil A350-Tuna Blue] ( http://www.kessil.com )
I am really curious about the new light colors.
For now, there are the old 4 lamps with 4*24Watts T5 each, in order to let the coral adapt to the newly changed bulbs. I’ll give them a week or so.
The Kessils have separate adjustable “blue” and “white” channels. For a start, the white will be set so something around 60%, the blue 50%.
With this, power consumption should be lower than the stated max. 90Watts and also lower, than the 4* (4*24Watts) T5s with LED having more PAR.
