Halogen light fixtures

Kirkll · November 06, 2022, 09:45:12 PM

I need some help here guys.

I bought a couple of these low budget halogen puck lights for my spray booth to help keep it warm in there. I installed a couple 75 watt G-8 halgen bulbs in them, and they didn't last 3 hours before i had a serious melt down....

I mean.... It's a good thing i didn't leave them on over night , or i could have had a fire on my hands. These little 75 watt G-8 bulbs get HOT! And.... i'm ok with hot. It's why i bought them was for heat.

They have got to have metal , or ceramic shielded fixtures rated for 75-100 watt G-8 bulbs, but i cannot find them anywhere. Any ideas?

Weather is getting cold at night here. We had half snow , half rain today. I've been using 3 - 150 watt incandescent bulbs to heat my little spray booth, and thought i'd get changed over to halogen lights with the incandescent bulbs getting harder to find.

Screw the halogen. They get way too hot and they don't last. LED is what you want. I know they don't get hot, but halogen is not what you want. JF

No.... Halogen is exactly what I want. LED is great for low cost lighting, I want a heat source as well as light.

I was hoping someone could point me in the right direction for finding a robust fixture that can handle the heat without melting. I guess I'll have to contact a specialty lighting store. Kirk

What about Floodlights?

Kirk I think Bugs mentioned there are metal fixtures for puck lights.

I spent a bunch of time searching for fixtures that would take a 75-100 G-8 bulb, and couldn't find anything at all. I mean..... they make the high watt bulbs....So there has to be fixtures that won't melt down after 2 hours of use.

I'm going to try contacting a commercial lighting company and see what they recommend. Kirk

Good choice Kirk. All else fails. Contact the commercial people. We have to at work to find out what works and what's not going to work. JF

Well i looked all over the place and couldn't find a fixture that would take the high watt G-8 halogen bulbs. but i did find some ceramic base units , and built my own light strip. I'm testing what kind of heat they are generating right now.

Here are the base units

Not surprised! Those pucks usually have between 15-25w bulbs. 75w, even in a metal puck housing would get too hot. I guessing yours were plastic? Did you leave the lens on them?

I like the homemade fixture

Hope you are not using those G-8's while spraying, those pin connectors are not sealed from the atmosphere.

I never thought about that Buggs... You think there might be a fire danger risk spraying with those on?

I'll tell ya what..... 6 of these 75 watt G-8 bulbs put out a lot of heat. These could easily be used in a hot box bow oven.

I think i'm going to build a smaller version with 4 bulbs using sheet metal and ceramic tile to heat my boat in seriously cold weather. I've got it in a covered boat shed out of the weather, with a full canvas top and windshield. When it drops into the low 20's for a week at a time, like it does in February sometimes, i like to have some heat in that rig. I think this would work excellent. I'd Just set it on a piece of ceramic tile.

Not so much a fire, but an explosive fireball. Probably not a huge risk, especially if you have good exhaust, but with explosive fumes, I don't think any risk is worth taking.

I know you like anecdotes, so here are a couple. Years ago I was doing finish work on some cabinets on location, which was a garage turned spray booth. I hired a guy to help me move material. We would spray a batch with Laquer and after it flashed off, open the garage door to clear the fumes. One time after spraying, I hit the garage button and as the door is rising, the dude lights a cigarette while the room is still swirling, full of fumes. I literally dove under the door, expecting to be burnt to a crisp. Nothing happened, except helper dude was sent home.
What caused my panic was knowing a guy who was in a similar situation working in a basement when a carpenter open the door while smoking and ignited the fumes. My friend Paul was badly burnt and lasted about a week before he succumbed. The carpenter survived, but was also burnt bad and horribly scarred, physically and mentally.

I had an old single bulb fixture hanging in my spray booth go up in flames not long ago. Fortunately i was not spraying at the time, but it scared me badly. I was about ready to run for the fire extinguisher , but it flamed out pretty quick. I had been using this fixture for many years, and why it decided to go up in flames is beyond me..... I had just turned it on, and it shot a 3" fireball out the side.

if i'd have had it happen while spraying, id have been toast.

I do have a pretty good exhaust fan running while spraying. I rigged up a 6" squirrel cage with a 6" exhaust hose that was used for a down draft stove top unit. It definitely sucks.... In a good way.

I also keep the door open to let more fresh air in as the exhaust fan runs. My spray booth is tiny by professional standards.
