LED Light Bars!

[IlluminatingBikr]

I just found the LED light bars. The come in preset lengths between 1.5 and 48 inches.

Check these babies out! /ubbthreads/images/graemlins/buttrock.gif

dude, those would go great along my stairway.. there's a problem with the circuit there and lightbulbs burn out every week..

 

[IlluminatingBikr]

If you go for it, be sure to make a post about it and take some pictures! /ubbthreads/images/graemlins/grin.gif

Must....resist....

Would sure beat the GITD paint I've got on the edge of the one shelf in here (nicely at eye height that thing... and this being an L shaped room, easy to walk into in the dark).

Hmmmmmm ...

Desk-edge lighting for my keyboard, some edge lighting for my computer room, some backlighting/wallwash behind the flatscreen TV in the livingroom, some lighting around the deck, some - AAAAARRRrrrrggghhhhhhh!!!

One can go bankrupt with things like this. /ubbthreads/images/graemlins/jpshakehead.gif

Very nice... I'm sure if we think hard enough we all can come up with some uses for these. /ubbthreads/images/graemlins/grin.gif They remind me of the slim police style LED lightbars that I'm starting to see more and more of. I wonder if they do group buys on these things?

>problem with the circuit ... lightbulbs burn out every week

Um. I _know_ I read something about this symptom ten years ago when rewiring my house, associated with lights that get brighter/hotter momentarily and burn out fast.

It's a red flag warning for some wiring failure that can eventually overheat the wiring in the walls -- not hard to fix. Hope you get an electrician to check.

And, oh yeah, the light bars look great. I knew I'd been keeping that 12-volt regulated power supply around for a reason. These finally might be the whole-house submarine-red-lighting I've long wanted for nighttime. AhOOOOOgah! Dive!

LOL hank /ubbthreads/images/graemlins/smile.gif

Try some Red luxeons too, and a cheap incadecent red colored party bulbs do a really good job of even saturated red lighting.

 

[RonM]

Since they run off of 12V those could be great for boat cabin lighting. White bars for general illumination and a red bar to protect night vision on evening sails. Cool.

The link no worky for me.

How's this: http://www.ledlightingsystemsinc.com/pages/LightBar.5/lb1050s.htm

 

[IlluminatingBikr]

Thanks Darrell. Seems my link died, as it did work a while ago.

Question: I asuume these can be run off of any 12 volt power supply that is direct current? Why is this?

 

[Darell]

Any 12V supply that has enough current, yes. I'm not sure what you mean by "why is this?" They put enough of the emitters in series/parallel with the correct resistors to make each length work at 12V.

Nice! /ubbthreads/images/graemlins/thumbsup.gif How are the LED's wired? Are there resistors and if so does each LED have it's own resistor? Thanks.

Really cool! Ok, where's that credit card... /ubbthreads/images/graemlins/grin.gif

 

[Darell]

NightShift - do you have those boards made up? I mean just the board with traces. Selling any? Just what I've been looking for (didn't want the hassle of soldering them up on generic board stock!)

 

[IlluminatingBikr]

Nightshift,

Did you get your LED bar from LED Lighting Systems Inc.? What length is yours? I assume it's the non-water resistant version?
