Hi all,
My tank is comes with a 2 x 18 W lamp and they are pretty much insufficient.
Incidentally I have 2 lamps near my tank, one is incandescent and the other is halogen. I wonder if I can use these 2 to provide lighting for my tank?
One thing for sure they produce a lot of heat and I can only shine those light in from the side of the tank.
What are the adverse effect of the heat from sides of the tank? Does the yellowish light from incandescent and halogen affect the plants?
Regards,
J
Both incandescent and halogen aren't suitable, because their light output is, in layman terms, not white, and also they produce a heck load of heat.
Heat is something you do not want in Singapore or your planted tank
Heat from the top or side or bottom of the tank is all the same, it still heats up the tank and your plants/fish will not like the temperature.
yes halogen produce heat i have no idea to your singapore needs but i can say white shmite.
I use to buy into the full spectrum idea. but when i could not find a fixture for my needs.
I tried architectural QUARTZ halogen lights " desk lamp" and all i can say is a picture is worth a thousand words. but yes becareful with halogens.
They burn very very hot and they can crack your glass if there to close.

I should be working not posting
The thing with Halogens are the CRI-colour rendition index, is pretty warm, so if you like the yellow look then it's fine.
For me it makes green leaves look mite sallow for my taste.

they are very yellow indeed, but with the open top i desired the smallest highest watt light possible the fixture is no more then 6 iches long by 4 1/2 wide by 2 1/2 tall yes i sacraficed yellow for not blocking the waterfall but as you can see they do work for a planted tank. There other benifit is that they cost 42 dollars each compaired to 350- 400 dollars.
If prefer yellowish look, perhaps could use warm white lighting.
I am using them to let plants at the side of my tank recieve light. Does such yellow light produce more algae?
