MR16 bulbs - Sealed or Open?
I've got track fixtures which take Halogen MR16 bulbs. It seems to me (please correct me if I'm wrong) that I can either
1) Use "open" bulbs, which then get covered by a glass plate which comes with the fixture, and attaches with clips, or,
2) Use sealed bulbs and put away the fixture-supplied glass plates.
Is there an advantage to one over the other? I'll be using the Ushio Superline Reflekto (coated back) bulbs. They're available either open or sealed.
Thanks for any guidance.
