Non incandescent bulbs?

[clare]

Sylvania 15 watt Osram/Sylvania reflector (par) bulbs in recessed non-insulated ceiling (pot light) fixtures. number on the bulb says cf15elbr30frost

The inccandescents were, IIRC, 60 watt PAR32. in the same fixtures. Just replaced the last one, installed in1998, over a week ago (and replaced it wirh the Sylvania that lasted 30 seconds). I also have some Philips Marathon 15 watt PAR32 CFL bulbs in service - less than

2 years yet, but still working

Tody is the second day we've had the AC on here in Central Ontario this year. Most summers are MUCH hotter and more humid.

I suspect those are minor improvement over whatever insulated ones for CFL overheating. For CFLs, I like to refer to recessed ceiling fixtures in general as "heat hellholes".

Philips has, as of last time I checked, a product line of CFLs with non-dimmable ones up to and including 23 watts (and not including 25 watts) being outright rated for use in recessed ceiling fixtures. These are not PAR floods, but there are snap-on flood-reflectors available for these. I strongly recommend using the wider R40 one as opposed to the narrower R30 one if the R40 one fits with at least almost 1/4 inch of air space around its rim for convected air to flow around.

Thanks for this info - makes me think 3.75 inch diameter frosted reflectorized floodlight with bulge approaching the base. This leads to a bit of homework for me to do to see if the problem you had with this one is common enough to show up in web searches. Please feel free to nag me here in the likely event I get get sidetracked by the other $#!+ that I do, such as a "day job" and a "side job", a website of mine that I need to work at at least a little for, and spending time and some effort to maintain a relationship with "someone special" that I would refer to as my spouse if PA marriage law was like that of Canada...

Thanks for what you told us here so far - but I fail to see manufacturer or brand, or part number specific enough to confirm or rule out vibration-resistant filament design (less efficient), longlife version, halogen version, whatever.

This slightly reinforces the good sensation that I have received for Philips CFLs. Philips is one of the "Big Three", all 3 of which I have found generally better in USA than others for CFs and lightbulbs in general. The other 2 are Sylvania and GE.

I have noted already as a weather and atmospheric science nut that the Ontario-to-Hudson-Bay area had an especially cool July, as part of mid-year so-far having generally northeast and northeastern-"MidWest" USA and nearby region of Canada running notably cool. This occurred during a time period having a slightly wild swing in global temperature as determined by interpretation of satellite data for "lower troposphere" and where the global surface temperature upticked a bit from "warm but downturning the global warming trend" to "warmth of 2004-2005

*maybe-maintained*.

I still note that the coolness of NE and eastish-N-central USA and areas of Canada from such to around Hudson Bay did indeed occur. I merely say that this cooling is a temporary one of maybe 2% of the globe's area.

Getcha one of them newfangled LED dropcords, sounds like they were designed for you!

I always use the bulbs designed for drop cords, coated rough service incandescent bulbs. Drop the cord and it stays lit.
