Duckworks Temp??

rv8or · Post by **rv8or** » Mon Nov 06, 2006 10:58 am

Does anyone have any info on the temp. a Duckworks light reaches while in use? For the various bulbs?

I am using a primer that is flat grey, and would like to paint the light bays with a "chrome" spray paint. The can says not to use it in applications that exceed 200 degrees. Seems pretty high, but want to check to make sure.

I'm installing the rectangular Duckworks, and will probably go with the 100 watt bulbs.

Thanks for any insight--

Joe

Just curious,
Is it too late or have you already primed this area? I just left my light bay bare aluminum. No temp worries then.

I say spray it!

It isn't like anyone would really be able to see inside anyways. Besides, I dont think it will have any ill effects. I plan on spraying mine!

I'd be nervous about that. A light bulb puts out a hell of a lot of heat, and confined in a small space it could really cook. 200 F isn't very hot. It might end up being inconvenient if your chrome paint caught on fire. But who knows? Maybe the aluminum will wick the heat out effectively. Why not drop the Duckworks guy a note and ask him?

Dang.. I never even thought about that!

I'm using the 100w and have already installed them in my 9A wing bays.
The bays are painted with MarHyde self etching 1-step primer (rattle can).
However, I did keep the lamp mounting surface clean.

Thanks guys. Still noodling on this one. Gives me something else to worry about, rather than the impending leak test on the tanks!

I have seen/felt a lot of heat coming off of landing lights before on larger airplanes. But I'm just about convinced these "automobile" bulbs can't get hot enough to do any damage...people would be melting lenses, burning up car parts all the time with so much less cooling airflow. 200 degrees is REALLY high...rain drops would just about vaporize on your headlights, and you'd certainly be able to feel the heat thrown off after parking your car (that's PAWWWKING your CAAAWWR for you Boston area guys).

I was sure Brad would run out and conduct more experiments on my behalf! I may have to find another Leader for "Follow the Leader"

Scott--
The ribs are primed, the DW pieces and the skins are not. I'm mainly thinking about painting the portion of the rib that is visable/exposed in the bay. Those ribs aren't all nice and shiny like the rest to begin with, primed or not!

The LE is not permanently assembled yet.

If I can keep my humble skills from scratching the rest of the alclad up, I'll probably leave the other parts bare.

Thanks for letting me think this through publically--

Aluminum foil? Reynolds Wrap? Maybe you could cover your ribs with a shiny material that is heat resistant. Just trying to think out of the box.

You've been waiting to use that line somewhere, haven't you!

Yes, and I am feeling much better now.

BTW, I am up to speed on the whole thing.

Your dog ISN'T fat, that is the breed standard.

Alotta people see Wyatt and think he is fat, that is until they see him in his spring cut and he looks like a boxer! It's all fur!

CJ, I admit, it was a bit of an inside joke, but I am glad to hear you are up to cruising speed.

BTW... I've been singing your song to Sonoma all night...

I would never disgrace that great looking dog with a comment like that! She's a beauty IMO!

No Caymus yet, I'm going for the "Extra-long" cure. Actually, I'm just too chicken to do the testing.
