Re: Standard base Halogen bulbs
I have some 50 watt halogen bulbs in the track lights in my living room. All are 120volt screw base lamps but of different brands.
I orginally started with Sylvania Capsylites from Lowe's in two of the track fixtures then later added Philips Masterline halogens from Home Depot in the other two. Great improvement over the 65 watt normal incandescent reflector floods we used to have, now I get more light where I want it. Being that the lights are in a high ceiling living room, compact flourescents, even the reflector versions, didn't have enough "throw" to reach to the couch where my dad reads all the time.
As for lamp life, the box says 2000 hours for the Philips; I forgot what the Sylvanias were rated. However, I did have one Sylvania Capsylite and two Philips lamps go out prematurely. The Capsylite seems to have burned out normal but both Philips bulbs died with a loud POP! and a tinkeling sound. When I changed the bulbs, I noticed something loose ratteling around inside. After smashing the glass open, I found out that the halogen capsule inside had actually exploded and there were tiny peices of quartz sitting in the bottom of the reflector. I bough a new Philips bulb from HD to replace it though. The Capsylite blew when I was trying to adjust the fixture since we had rearranged the furniture so I do feel vibration was somewhat of a factor for that. I still have one Capsylite still going strong. As for the other Philips bulb, it blew just three weeks ago. I am now trying out a GE edison 50watt flood there.
Heat output dosen't seem too much but then again, they are up high so you don't feel it unless you get out a ladder and put your hand a few inches infront of the bulb. They do seem to get a little hotter than a normal bulb but that seems to be IR radiation, the halogen capsule itself is sealed under a vacuum in thick glass so the outter bulb still gets hot but it dosen't seem much hotter than a normal bulb. I do notice the metal screwbase getting very hot though but the sockets in the track fixtures are ceramic so it dosen't seem to be a problem. They are operated in a base up position at a slight angle with the top of the fixture closed.
I have a GE 45 watt Halogen Outdoor wide flood in an outdoor fixture with a 100 watt incandescant PAR bulb next to it. Great for grilling at night but I don't sleep with it left on. It dosen't get used too much though except when I'm emptying the trash or having a party.
My last bulb is a 35 watt MR-16 sized GE Edison spot bulb that has a screwbase and also runs on 120 volts. I use it as a task light in my room but I've since replaced it with an Ott Lite compact flourescent desklamp but I still pull it out if I'm doing close up work that needs more focused light than a CFL.
