Poor man's 10K?

[reefburnaby]

Hi,

The regular types are real 6500K lamps and the type R are labeled as 6500K, but they are closer to 10000K.

Personally, I have read up on this Poor man's 10K and it will only work if you have a very powerful light source (like a 400W 6500K Iwasaki). Since PAR is the most important number, and filtering doesn't increase the PAR (it only decreases it), the filters are only for asethetic reasons. Here's a trick you can try, rather than placing the filter above the lights, put it on your viewing glass (like one of those DIY tinted glass). Corals are happy...you'll be sort of happy and save some money at the same time.

Personally, I would just get some 6500K Iwasakis and get a couple of overdriven actinics.
