48v work lighting solutions

[Tripplett]

While planning my first solar system I'm also thinking about what can go wrong. In the event of a power outage AND an inverter problem I'd like the ability to run some lights directly from the 48v rack batteries. So I hopped on Amazon and started searching for 48v LED lights. I found these below that look like they'd fit the bill.

Having flashlights is handy if you remember to have batteries or keep them charged, but having a light that can run 48v direct would be even better IMO. I'll either wire them directly or put some alligator clips on them - through fused lines of course. Has anyone else worked on some type of solar room lighting that can be powered directly from the battery racks? Am I searching for a solution to a problem that will never happen? Thanks.

Actually looks like they are 48W, 10-36V

there are plenty of vehicle style lights that are 48v



mount them and put them on a automotive style switch.

problems with "light bulb" style (medium base) is that you can mistake them for not-48v and screw them into reg 120Vac socket.

This claims 10v-60v
I have some old light bars somewhere, thanks for the idea.

great idea, currently I use some 12vdc led rope

here is vehicle light that says 10-48v

I would be leery of something rated 48v max. A typical 48v system can reach much higher. (57v in my case)

good thought, my battery tops at 49v - actually 50.4v, but I don't charge that high

Incandescent bulb might still be bright enough on 48v.

Funny story.
Many years ago I had my guys install a bunch of temporary lights on a jobsite. (Over 100)
The supply house mistakenly sent out 12v bulbs.
It was all done and ready before the temporary service was energized.
When I threw the breaker on, we all needed new shorts. lol

of course you did

Pesky zeros. They don't mean anything anyway!?

I prefer the COB style LED strips for uniform light. Here's 65 feet of 48v for $75ish. Has sticky tape back so just put it where you want. https://www.amazon.com/Flexible-Commercial-Shopping-Restaurant-Included/dp/B0BGHXVNV6/

I bought some of these last year. Connected to one of the batteries and it’s on all the time.

Also, you could put four 12v lights in series too. That may or may not be cheaper.

Good point on the COB, I wired some strips into the reverse circuit of my quad; night and day difference.

Here's a puck rated for 60v but appears to ship from China.

You could also get a step down buck converter to 12V. That opens up the number of possibilities for these lights, as the automotive light bars are often built to be run off 12v car batteries.

Did they already change the price? $97 now.

Did they already change the price? $97 now.

But now with a $20 coupon. Kinda dumb price games they play.

 

[Tripplett]

Oh I missed that there was a coupon.

Dang. I’ve been meaning to post this same question. Good info.
