led lighting
 
i'm working on this turntable project and wanted to put an under cabinet type led light on it. i've done several of these turntables with incandescent lamps on them. on the others i just wired the lamp directly to the turntables power supply.

i'm not familiar with LED lighting. can i do this with an LED strip? are they different voltages? would it interfere with the turntable signal?

would the flexible LED strips work?

You can buy LED strips for something like that at wally world, kmart, etc..... They just plug in like an ordinary lamp.

Not unless it's being powered by a car.... you'll notice it says 12 volts.

can you recommend a particular strip or stick that is low profile?
i tried home depot and there was nothing really that would fit well.
walmart is a good drive and i don't expect to find anything there. always go for things like this and never find them.

What dimensions are you working with?

SPIT 09-18-2012 03:11 PM

13 3/4 x 3 1/4 x 1"

some of the strips i've found online look good, but they all require adapters. so if i'm wiring direct to the 110 power supply which also feeds the turntable i was thinking this could cause some feedback in the sound. not sure.
can i find 110v strips?

LEDs are low voltagem bot 120 volts. In order for them to run on 120 you need a voltage adapter. Make sure whatever you buy is UL or CSA rated. You can use the LEDs listed in your post IF you buy a good voltage adapter. HERE is an example of a good one. If you don't buy a good adapter you will get all kinds of problems like buzzing, humming, etc. It sounds like whatever you buy is going to have to be ordered online. HERE is one example. I'm sure Amazon and other online retailers have other similar products. Another option would be to use a battery powered light strip with rechargeable batteries. If you're concerned about noise, then that's your best bet.

ok. so i'll need a driver. expensive.
i also found some 120v driverless strips online for $40.
since i'm planning on doing a lot of these projects...is there a cheaper solution?
is there a cheap way to mod a 12v strip to work on 120 without a driver and without issues?

SPIT 09-18-2012 04:50 PM

or might there be an incandescent solution that would fit those dimensions without being too bulky and hot?

I was just at Home Depot and checked for you. They have one for 4.00. The smallest one was 2 feet but it was a 'rope' style so maybe you could fold it in half. There are some LED power adapters here but you'll need to contact them to see if they are UL listed.

The same web site you posted from has a whole section designed for home use: http://www.oznium.com/home-led these either have adapters or are designed for 120v.

i have that 2 foot rope one. it puts out very little light.

didn't notice any strip lights for 120v...please point me to them if i missed it.

i'm wondering if i can get the ac adapter with a 12v strip and mount it inside and wire it like a transformer...directly to the turntable power supply?

This one http://www.oznium.com/bright-flexible-led-ribbon-strips this one http://www.oznium.com/flexible-home-leds and this one http://www.oznium.com/slim-line-led-fixture have options listed for the required AC adapters for 120v.

AngelArs 09-18-2012 10:31 PM

THIS 2 amp one is UL listed.
