Machine lamp.......

I thought the idea of a ring lamp, around the spindle of my mini mill was a great idea.

So, this arrived yesterday.......   http://www.ebay.co.uk/itm/200678890770?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

I then realised, I didn't have a 12v transformer!  :palm:

This is on it's way......    http://www.ebay.co.uk/itm/280622615926?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

As I know nowt about much, to do with led's and such......

I'm asking, they are compatible aren't they?

It will be interesting to see if they are as I have no idea what Waltage means? A cross somewhere between Voltage and Wattage? If it works David, I shall be making one up myself, have thought about it for a while now and seems easier than placing my own LED's in a ring, lol :thumbup:

Specification:

Color: white
Color Temperature: 8000 ± 200K
Lumen Voltage: 700 ± 5% Vrms
Frequency: 40 ± 5%
Brightness: 45,000 ± 10%
Current: 6.5  ± 0.5mA
Waltage: 3.5 ±10%W
Life Time: more than 15,000 hours

I rigged something up like that Dave using a LED torch thing from aldi and a transformer from a phone or something it worked fine for over three years but the led's were started to give up one at a time, so got myself one of those goose neck jobs.

Moo:
I think you are going to find that they are not compatible.

That ring light is a CCFL (Cold Cathode Fluorescent) tube. They need to be powered up by a low current high voltage power source, usually a small inverter circuit. Looking at the specs on the ebay page, it looks like it needs 700V at 6.5mA to operate it. What you need to look for to power it is a CCFL_Inverter that has the correct output specs for that tube.

Something like his: http://www.ebay.co.uk/itm/2-X-Spare-INTERFERENCE-inverter-CCFL-Angel-Eyes-Light-Halo-Ring-12V-/200678592230?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item2eb9604ee6#ht_3958wt_1396

This inverter still needs 12V to power it up on it's input, so you will be able to use the 12V 1A LED Driver you have already ordered to do this.

Waltage Steve? Hmmm..... Hadn't spotted that! Even more confusing!  :scratch:

Stew. I spotted your lamp changeover some time ago, and being a cheapskate, bought a battery powered table lamp.
It does the job. But, you know how it is, everything's closing in. Not much room to stand it, close enough.......
