Hey all,

I know most of you reef guys probably run MH lights, but I figure a reef forum probably has some lighting gurus around. I'm converting a 70 watt HPS security lamp to aquarium duty for a small setup. My problem is I have had no luck finding a bulb with a natural spectrum. Seems like they only make grow specific bulbs for the higher wattage lamps. Any tips or suggestions on where to find one are appreciated.

High pressure sodium bulbs are rare in this hobby but not unheard of.However the 70 watts is the killer.I have a few at work that are 100 watts most are higher.I am guessing that those are from 3 to 4000k and not at all suitable for an aquarium.I can look in some catalogues at work tomorrow.What base does your fixture have?

Medium base on the fixture. I realize that 70 is an odd size and what I'm looking for might not exist. Just trying to light up a small tank for cheap.

This isn't for a reef system. When I did have time and space for a reef tank I did run metal halides. Just figured a reef forum would be a good place to find people that know lighting.

thanks for the response
