How do you have your lights set up? What distance from the water and how far apart? How often do you replace the bulbs?
I'm curious because I'm impressed. Very much so.  |
Well, the lights are equally devided in the hood. I use reflectors.
The lamps are 5 cm (2 -3 inches) from the surface. Normally I use 1 lamp every 15 -20 cm (10 - 15 inches). The lamps are T5 fluorescent.
There are some area's with lower light (left and right). But it is enough to keep the Glosso down. Replacement : when they are broken... According the techdata of these lamps, they will keep 90% of the power during there life-time.
Tomorrow I can place a picture of the hood.
