Confusion re types of MR16 light bulbs

Posted by spoonbill (My Page) on

Can someone please tell me the difference between MR16 "open-faced" and "glass-enclosed" bulbs? Is there any advantage or disadvantage to either type?
We currently have both types in use and are having a phenomenal rate of burn-out, for some reason. I need to order them in bulk, but have to clue as to which I should get. Thanks!

It has to do with the possibility of the halogen capsule exploding at the end of its service life and manufacturing other issues (see link).
You should buy them from an electrical supply house rather than a box store. I like the Sylvania MR16 lamps. I've know them to last many years.

Here is a link that might be useful: sealed MR16

RE: Confusion re types of MR16 light bulbs

Thank you so very much - that's EXACTLY what I wanted to know. I'm now remembering, as we were renovating this house, the head carpenter telling me about a kitchen MR16 in a tract fixture exploding and scaring him half to death. I've used versions of these bulbs for years, as an amateur - my life quest has been to find the extremely narrow beam spread ones which are spectacular aimed down at, say, flowers on a table. It makes the flowers look like they're glowing from within, since there's virtually no light on anything else. In any event, I'd never heard of them exploding, and assumed the carpenter's experience was just a fluke. I'll take your advice and try the Sylvania ones - thanks again!

The sylvania bulbs are ok, but the best are the ushio bulbs. The sealed unit also has UV protection. But either sealed or non sealed is ok, if you have the UV glass shield that come with some low voltage cans or other lights that take the 2 pin mr-16.

I will check out the ushio, too - thanks for the lead. I've never heard of the brand. These aren't in a can - just essentially "naked" in a track fixture. It's maddening, because MR16's are no fun, at BEST, to change, but in these un-cheap tracks, they're practically impossible to get out of the little metal housing, for lack of the correct term, that holds them. There's no room between the bulb and housing and you wind up having to exert tremendous pressure at an incredibly awkward angle.

RE: Confusion re types of MR16 light bulbs

Yeah, no worries. The ushio are great mr16 bulbs. You can also get them in a 20000 hr bulb. What tracks did you get? Tech?
