EDIT: Posted this in the DIY bit, but here might be more sensible? I have been toying with the above for a while now... I use spots for background lighting in the living room which also houses my projector (use low wattage ones in the bedroom as well as reading lights) all are dimable, but the heat/power usage is a bit of a putoff. Led based ones sounded great on paper (low power/heat) but i am getting conficlting advice about diming/whiteness... I poped into focus last night and picked up the white led gu10 and it worked - but in no way, shape or form could it honestly be called white, bright blue seems more acurate Anyway, does anyone on here use them and can anyone recomend any white ones or higher output ones? Cheers, sean.
