RE: [plant_list] [APD] halogen lighting for aquarium

The problem is that halogen bulbs produce a very poor plant spectrum, and
also cast a very yellow light.

Subject: [plant_list] [APD] halogen lighting for aquarium

As general diffuse lighting for an aquarium, a fluorescent lamp would be
more efficient. If you need to focus a relatively small wattage onto a small
area, then wouldn't a small halogen with a built-in parabolic reflector be
better? You can actually focus and direct the light with these and getting
the right amount of light onto a small area, such as a patch of foreground
Glossostigma seems like an idea.

I've also used external halogen lamps for photographing aquariums. I mounted
them temporarily to the front and side so that there were no reflections and
so that "invisible" scratches in the glass don't show up. There's no reason
a display tank cannot also use lights mounted in unusual positions. Lighting
serves two purposes: a) for the plants to grow b) for seeing or
photographing the plants.

I find it hard to believe that nobody else has tried this!
