LED lighting inside cabin

[William_H]

I have just received some of these for a try out.
http://www.banggood.com/4W-48led-COB-LED-Chip-480mA-WhiteWarm-White-For-DIY-DC-12V-p-959059.html
They seem to be very bright and low profile.
It appears the LEDs are printed onto a metal backing plate. Hopefully with good heat dissipation.
They have 54 LED diodes and are rated at 4.8w at 12v.
Seems like they would be very easy to glue to a cabin ceiling. Perhaps an alternative to strip LED lighting.
Anyone got any experience or inmmterested in experimenting? olewill

Main issue I see is in making them a comfortable light. The strips can be mounted behind grab rails and light bounced off the headlining. Suggest it is worth thinking about this. Good luck. M

4w LED will be like having a car headlight on in the cabin?

My 7 interior lights take just over 1A, one of these is c. half of that.

Looks good for flood/deck lighting. I may buy and try one.

Trying to keep up with LEDs is fun! (and unlike these, avoiding buying old stock...)

I think you are going to have to get the heat away. It's a lot of power in a small place and it is heat that destroys LED's.

A great product but it's a starting point in the project.

I might put them on a strip of ally, spaced, and see how they last.

You can effectively use a PWM dimmer with LED's and increase the life tremendously.

Keep us in the picture on this fascinating project.

Actually on test the power is a lot less than quoted in the blurb. Something like 1/3 of that at 12v input. Presumably that means they can take 14v without any problem.
Yes the metal backing looks made to disipate heat and not hard to press up against a larger heat sink. Still quite bright at 12v. olewill

I fitted a couple of strips like that to replace a floursecent light (had it's own separate cover which I re-used), but generally there are a lot better options on the Banggood site if you're planning to mount them in the cabin and avoid the blatant DIY look.

These for example give out a good light. http://www.banggood.com/2X-50cm-9W-...f-Rigid-Strip-Cabinet-Light-12V-p-940643.html

You can trim them to size too.

There are lots more options if you want to do a bit of browsing of that site.

Watch for VHF interference!

Watch for VHF interference!

Or even listen for it.

I can state that I've fitted several Bangood LEDs, including the ones I linked to, ones similar to the OP's picture, red LED strips and red LED truck sidelights (for night vision) and several G4 and BA9S replacement bulbs (as well as LEDs from multiple other sources) and have suffered no VHF interference. Neither have any blown so far despite having two Sterling chargers (mains and AtoB) that like to up the voltage.

Meanwhile, the fridge does like jamming R4 LW.
