Well I dropped one of my Philips Hue LED Spot bulbs and broke the glass surrounding but the actual diodes seems intact and it powers up fine:-
It's a full colour bulb and the colour temperature can still be changed etc. so I was wondering if it could be used to germinate seeds with? Looking at the diodes on the board, the orange ones look the same as most you see and there are a couple of red ones so I need to find a datasheet to check but It looks OK to me for the short period it will be required for. Anyone had any experience using HUE bulbs at all?
