LED striplights.

[Thepipdoc]

I'm considering buying LED's for under shelves, ledges, seating etc.
They are supplied with a 240v to 12 volt dc transformer - see spec below.

The question I have is, can I wire these LED's to run directly from the boats battery source? ( this might seem like a daft question but I'm really not sure!)




* Self adhesive, ultra high output LED strip lighting
* Ideal for many applications including display, decorative, sign, under-shelf, and emergency lighting
* Flexible strips can be applied to curved edges such as pillars and tubes
* Allows for frequent cut points anywhere along the length of the strip, power is then provided at the adjacent connection point
* Different colours can be combined, with solder points every 50mm
* 60 LEDs per 1m length with 15mm separation between each LED
* IP54 rated
* LED Strip Kits comprise of 2m length of LED Strip lighting and a 10W 12V LED driver
* Addtional lengths of LED strip are available in 1m lengths
* Additional LED drivers will be required if exceeding 4m length of LED strip or if exceeding the power supplied by the original driver

Technical Data
Voltage 12V DC
LED Power (Single) 0.035W (R/Y), 0.08W (B/G/W)
Operating Temperature -40°C to +85°C
LED Strip Dimensions (WxD) 10 x 2.5mm

like most sensitive electronics, they can be a damaged if switched on we you start the engine, and get a surge as the alterantor fires up.

The best ones have a voltage control circuit in them.

 

[Barry Jones]

There's not enough information there.

They are nominally rated at 12V and designed to operate through a mains transformer.

It's possible that they will run from higher voltages (i.e. when your engine alternator drags the DC supply up to 14 volts-ish), but its impossible to know.

Either try one to see if it fails after a while OR
run them through a DC regulator which will take the varying alternator/battery voltage and keep a constant output on the LEDs.

I did mine with standard 12v 24 blue LED stripes from HK, and wired it in through my existing lighting circuit, in total running 8 24 led arrays, 2x high intensity white in engine bay area, 2x blue in rear storage seating area, 2x blue front seating storage area and 2x inside cuddy at front bow, for a winter job im going to install some underwater LED underneath the bathing platform.

LED came from HK and priced at £2.00 for a 24 led length see link.

see my vid after install of LED
http://www.youtube.com/watch?v=YY3TxxvPbls&list=WL85D8467DB3369A34&index=1

had no issue with lights or circuit and completed a current test to see what the drain is with lights on and it only 0.80 amps

Having just (today) completed changing all my deck lights to led I now have approx 20x the amount of light for about a quarter of the former power consumption. And so far no issues with differing voltages.

Did you simply take out a low voltage light and connect an led (without voltage regulator or converter)?

 

[longjohnsilver]

I'm no expert, one of the replacements was a Hellas marine unit, all the others are light strips which have what look like diodes between each light and the first I did a few years back was a simple strip of LEDs with a sticky back. And yes with all of them I simply connected them to the existing 12v supply.

I bought some of B & Q's outside decking lights, powered by mains through a 12v transformer, I removed the transformer and installed them into the boats wiring circuit via a switch, looks fantastic and no problems at all.

Hope this helps

This is exactly what I'm trying to do.
I reckon I'll do what Barry Jones said and try one of the LED's and if that doesn't blow the rest should be good.

A difficult question from what you write as the specification says nothing about the electronics 'Capability'.

- I shall assume all internal? If so maybe OK .. but if any outside I would expect IP65 minimum.
- They are designed for "constant current" (the transformer does that normally). If the LED engine circuit has a very 'tight' tolerance (eg 11.5-13v) then they may just fail. The spec is non-specific.
- The length of your wiring ( and gauge) may result in overheating of cable/ light failure. No info on current draw.

I wouldnt .... but doesnt mean they arent perfectly viable.

I've stuck these on model planes and run all sorts of power to them up to 13v and they've been rock solid even after the odd crash - bright too, you can cut them down or link them together and for $5 not going to break the bank.

These are the exact same lights I'm considering fitting but they are a fraction of the price I've paid! Am I right in thinking this is a USA site so I would incur import duty once delivered?
Anyway...........Today I actually fitted 2 strips of them to the saloon and they are certainly bright enough. If anything they are too bright. I'm very glad I fitted them behind a ledge so I can't actually see the LED's, only the white light.
Thanks everyone for your helpful comments /answers.

 

[thomshap]

They are a model shop in hong kong so you don't tend to pay duty for anything under $40, the lights are excellent, they do waterproof ones too.

 

[tinkicker0]

I have several 10" or so Neon tubes using the same transformer arrangement for hidden deck / storage pocket lighting and have had no problems whatsoever running them off the battery for the last 3 years. Power consumption is negligible.

 

[Colvic Watson]

Yes, and never had a problem with blown diodes. Everything from white strip lights under the cupboard to ceiling clusters and replacement bulbs. Maybe the cable run lowers the voltage!

I've been using these externally & internally for a year now, directly wired into the 12 volt system but agree that sometimes they can be too bright, so I bought a dimmer with remote controller.

Costs about a £5 but I can switch the lights on, off, up & down from the other side of the marina!

You have fitted a dimmer to this type of LED?

http://www.hobbyking.com/hobbyking/s...5F1mtr_.html

Not only a dimmer, but a remote controlled dimmer?
Do you have a web link for it?

I've bought both from HK and the UK but have had really excellent service from this company. They replaced a faulty string of LEDs and have been competitive on price. He'll cut lengths of LEDs to your required size and solder connectors on etc. Overnight delivery too!
