My lights are purely DIY stuff, as at a swap meet I bought 10 ARO as-220 vho ballasts cheap. Currently my reflectors consist of aluminum tape stuck to the top halp of my flourescent bulb tubes, blocking light from escaping to the top at all. Is there any value to this at all? Am I wasting my time? Anybody done any testing of this sort of set up? I assume decent reflectors could improve performance.
