After four of the 'studio' halogen MR16 bulbs burnt out, I went to get some more. Let me say I hate replacing these bulbs. Finicky work. I have considered LED lighting before and there are LED MR16 bulbs available. They are pricy, however.Today there was five bucks off from Ontario Hydro instant rebates. I've replaced five halogen bulbs and the results are outstanding.
The bulbs to get are the 'Bright White Light' ones from Philips. They are 5000K bulbs and my prints look great under that color of light. These ones are dimmable. BCMR10R16 35Watt.
Hopefully, I will never be replacing these bulbs again :-)
