 Re: ISO 70 watt HPS bulb
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? |
