High all. I've recently been given a two-tube fluoro light with three normal pin-sockets that I screw compact fluro's into. It has a hood and all that but what I am curious about is one of the tubes that was in it when I got it. It has no markings on it so I can't give any specs, all i can tell you is that it is about 30% fatter than a normal tube, and emits a soft yellowish glow (compared to the cool whites). Does anyone know what this might be. My friend says it might be a grow-lux or similar but I'd rather know for sure. Otherwise I'll just stick another CW in there. Or I just have a beefy Warm White globe?
