I have a hydrofarm valuebrite 1 reflector hood that I got used from a friend. I'm trying to use the optional air cooling so I'm looking for the glass lens and the flanges. Problem is the valubrite 1 has been discontinued and I"m having trouble finding the parts. So does anyone know if parts for the hydrofarm xtrasun XT1AC hood are compatible with the hydrofarm valubrite VB1AC hood? They seem to be the same dimensions and design. Any help much appreciated.
