herefishyfishy Posted April 8, 2004 Share Posted April 8, 2004 This may seem kind of weird but will halogen lighting work for reef tanks? Thanks, Alex Link to comment

Nanite Posted April 8, 2004 Share Posted April 8, 2004 I was thinking that Helogen lights might be cheaper than metal halide lights, because in australia metal halides are really expensive. Link to comment
herefishyfishy Posted April 8, 2004 Author Share Posted April 8, 2004 Would it have the same growing power has MH though? Link to comment

Chyendra Posted April 9, 2004 Share Posted April 9, 2004 Problem is they don't come in the same Kalvin rateings as MHs do. Corals need at LEAST 6500K and 10,000K-20,000K is usually best. Link to comment
1fish2fish Posted April 9, 2004 Share Posted April 9, 2004 Most of the available halogen lights have a kelvin rating of around 3500 to 4500 if I am not mistaken. THere are a few specialty bulbs out there that are rated at 6500k. I recently tried a simple xenon filled car headlight bulb, but found that it did not produce as bright a light as my 27 watt PC. My next experiment will be using a 50watt 6500k spot on the 1 liter I'm setting up. The spot only comes in model with a 12 degree spread though. This will suit my needs, but would be impractical for a larger tank. Link to comment
