Hey,

I was looking at some Halo cans and trims today and I noticed that the max for this particular trim was a BR30 65 watt or a PAR30L 75 watt. I was under the impression that PAR's run hotter because they are halogen, no?
 
Although halogens are par lamps you can also get par lamps that are incandescent. They are usually rated for outdoor use in floods whereas a BR lamp is not
 
Ah ha, thank you Dennis for that info, you learn something everyday. However, the labeling on the can and/or trim, makes no mention of the lamp being incandescent or halogen, as far as I am aware. Also, let's say that in this case the PAR in question is an incandescent; the PAR, I am assuming, operates cooler than the lesser wattage BR, but why? Why or how does the PAR run cooler?

That I cannot answer other than the glass is thicker but I am not sure that could make it cooler. Halogens definitely run hotter so I guess they have taken that into consideration.

Halo cans will take an R lamp that is 75 watt. I am not sure why the BR will only allow a 65.
 
My guess is that the lamp design has something to do with the amount of heat dissipation. Do they even make a 75 watt BR lamp?
 
Philips claims their halogena bulb is not any hotter than an incandescent.

I think the halogena is their halogen bulb.

Does the Halogen? bulb produce more heat than the incandescent bulb?

A. In general, a Halogen? bulb will produce approximately the same amount of heat as an incandescent bulb of the same wattage. The actual amount of heat produced by a bulb will vary due to, burning position, fixture type, etc.

IRC the BR lamps at 65w and 50w or less were exepmted from the federal energy regulations that went into effect around 1995. BR30 75w lamps are no longer permitted to be imported or manufactured in the US, but stores can still sell them if they stock them. If I'm a fixture mfg, it's alot easier to just eliminate hard to find / obsolete lamps from the "permitted lamp" label. /IMHO
 
Thanks guys for the replies, and Happy New Year's to everyone. Back to the topic here, bottom line, are these "Permitted" lamp labels referring only to incandescent bulbs or halogens as well?
