Can I run this LED light off my PD 9280? Should I?

The 9280 can power it easily; it's capable of supplying somewhere around 1000 watts. You would need appropriate wiring and fusing, 6 gauge or so wire. Most RV fuse panels wouldn't be able to have such a circuit, so it probably would require a dedicated connection at the battery or converter. That is assuming it's anywhere near the claimed 500W,...

Heat could be somewhat of a concern but it is spread out sufficiently that a bit of care and common sense should suffice to prevent trouble, assuming the light isn't dangerous by design.

I think this is far too bright for what you're intending, though. Also, as GordonThree says, the quality of the light will be pretty crummy. A halogen work light might be a reasonable and not too expensive alternative, though they do run hot so mounting or positioning should be done with care.

Thanks, trackrig.

I did do some research, and apparently the commercial SAD lights are way too dim -- much dimmer than what is used in the science studies for SAD. So that is why people are recommending other setups. You don't have to have them right in your eyes if they are bright enough.

Yeah, I wonder about the spectrum, too. Although apparently there is some evidence that the blue end is the important part.

Info on light bars for this use.

Or metal halide lights for better spectrum, more $$$.

I just thought I might try the cheap option first.

Thanks GordonThree. I have some of the Reveal lights (got them on closeout). They're pretty but not particularly bright.

Yeah, I believe you that this light will be ugly. But it might be helpful?

I have (physical) health issues that get a lot worse in cold, gloomy weather. I am sick as a dog if I cannot go south -- and I cannot right now, due to a dislocated hand.

I'm feeling stuck between a rock and a hard place, because even if the orthopedist ok's traveling, I am too sick to get out of bed and pack, etc. So I thought the light MIGHT help with that. I have a different light for vitamin D, and it helps a little... bootstrapping....

Naio,

I'd research a little more on the output from a SAD light mfg such as Alaska Northern Lights that makes them for use in all of the darkness in Alaska during the winter.

I have the large model Northernstar 10,000 with two lamps of 60W each. I think the 500W light you listed is way overkill.

If I remember right from my reading on SAD lights several years ago, it's to be within several feet of you and while the light doesn't have to be directly in front of you, it does need to be situated so the lights rays will enter your eyes. The effect of the light decreases with distance. I'm not sure how you're going to let a 500W light shine into your eyes from 2 - 4 feet away. I also have my doubts as to the light bar supplying the correct light spectrum.

Also while the light bar will be returnable, you have to do it within 30 days. Using a SAD light does change everything with one or two quick uses so it may take a while to see if the light bar is doing anything for you. Again, I think the 500W is way overkill for this purpose.

I doubt it's really 500 watts. So sure it'll run.

You'll be much better served going to Home Depot and get a few GE Halogen Reveal brand bulbs. They're full spectrum, including a hint of deep red and near UV. They also have an excellent color rendering index. This means colors look pleasant to the eye under that light.

The cheap industrial grade LEDs used in the light bar have a terrible CRI. They make colors look flat and skin look like you're a fallout survivor.

remember that scene in Christmas Vacation when Chevy Chase turned on his Christmss lights? the electric meter started spinning like a top and the neighbors were blinded. get ready to experience that with 50,000 lumens. if you're looking to get-away-from-it-all you'll be disappointed as you'll probably be visible from the space shuttle when you light it up.
