Steve ... take a look at the J&L website under lighting and tell me if the stuff that they are using for reflectors for MH are spectral aluminium ... the guys at the hydroponics store did say the stuff was polished aluminium with a 95% reflectivity which is the same reflectivity that the J&L reflector claims to have ... is polished aluminium with 95% reflectivity then the same as everbright or spectral aluminium ?
