I am working on a test chamber where the temperature will range between -4 deg. F and 176 deg. F. I am having trouble finding an LED troffer that will work in these conditions. Has anybody come across any LED lighting that might work in this room?

Thanks

 
Check with Holophane. They manufacture a number of industrial LED options that are suitable for some pretty extreme environments.

Not sure Emerson has something that high range..but they have something range from -4C to 50C..check them out

80C will required some serious heat sink!

 
Can you get a remote driver?? I think the LED is pretty tough. It is the driver that does not like heat

I believe you need to maintain a low maximum junction temperature on the LED. Since most electricity on the LED become heat and only maybe 30-40% becoming light, those heat needs to be dispersed to somewhere else. So, the driver is just another factor. If you have the driver separate from the LED, you need to run DC power all the way to the LED.

 
I ended up buying this one:

I talked to the manufacturer who said the driver is rated for 86C. I was still hesitant to buy it since it doesn't mention harsh environment and it seems like a simple food area light. I talked to the boss though and he said we should go with it. Unfortunately, I didn't get that in writing :)

 
^ not in the applications I've developed designs for. For harsh industrial environments, typically there are a multitude of operating voltage options available.

ya..the highest temp i found is 50C as well...no sure they make anything above to 80C...
That was used only as an example, not for the application in question. I was just demonstrating the different available voltage ranges for LED components.

That's not what the OP asking. He is asking high junction temperature LED.

I fully understand that and my comment was not directed at the OP. It was directed toward your comment of saying one "needed" to run DC all the way to the LED. Which isn't the case but now is off topic from what OP was asking. Semantics....

The style LED that I posted does have high temperate options as not all of their offerings are listed in their online product catalog.

 
Yes, LED lighting is an excellent choice for high-temperature conditions. It's often used in commercial kitchens and other areas where temperatures exceed 200°F (93°C). LEDs produce very little heat and are safe to use near food. They also have long life spans, so you will not need to replace them as often as traditional lighting sources.
LEDs emit a wide range of colors that can be customized to match your needs or preferences.
