It was left over from a job and I got to keep it so want to make use of it.

Ted1 would I have to run a wire all the from the fuse panel to use that connector and wire in the led light?

Check the input voltage of the white controller from the transformer. If 12/24v just connect it to your 12v supply via a fuse. The remote will control it via the white box. Note the cable size and do not exceed approved cable lengths as voltage drop will cause problems. You should be OK with 2mm DC cable for a van.

You would be advised to, but some people may just grab a supply from an interior cabin light/ licence plate light/ etc. There current draw is low enough.

freddyuk

Each circuit in a car/van is fused according to its designed load. If you want to risk it then ignore the advice but I would run a dedicated fused circuit. I think the light will be annoying if it is warm white for a worklight. OK for fancy ambient light.

Hi lads im looking for a digital dimmer switch,is this what they are called?
I want one that doesn't have a little coil in the back of it as i find they can be kinda noisey!

Is there switches that lower the voltage going to the lights digitally?

My electrician is almost complete the 1st fix for a new build and I need advice on 220v (not 12v)recessed lights.

-Am I correct in assuming that the fitting is independent of the bulb, i.e. I can start out by fitting halogens and then change to LED later on, without having to change the fitting.

-i will need to change the dimmer when changing to LED

-are there one gang double dimmers suitable for LED ? is there a max wattage on these?

Thanks !

why not just go straight for LEDs??

Is it Worth the Hassle & Cost of replacing 16 x MR16 20 Watt 12 Volt Bulbs on dimmers???

Is it worth the Hassle & Cost of replacing 16 Down-lighters that are only 12 Volt, 20 watt Mr16 bulbs ? (All Connected to 2 Double Dimmer switches)
They were all originally 50 Watt bulbs fitted but i replaced them with the lowest MR16 wat bulb i could find and that was 20 Wat! Any thoughts? It would mean replacing both double dimmers also of course.

Hey lads, which are better, these or the philips master ones? (eurosales have a 4w and 5.5w philips GU10 at the moment, E8.50 and 14.39 respectively) I think I heard it mentioned on this forum that the single cree philips are best...

Which? magazine rated the Osram GU10 7w at 83% and Philips GU10 4w at 80% so very little difference.

Incidentally the best dimmable they rated was TCP GU10 5w

An interesting development in LED mfg techniques, if it can be commercialised.

I am looking for a recommendation for a 12V MR16 Bulb.

It needs to be 12 volts as it is connected to exposed metal cables.

Something like this. http://www.qvsdirect.com/media/catalog/product/cache/1/image/700x700/17f82f742ffe127f42dca9de82fb58b1/l/f/lfsus20k-cable-5x-20w-mr16-low-voltage-suspension-cable-lighting-kit-polished-chrome_1.jpg

Hi all, hope I'm asking in the correct section, I was looking at the LED Strips on dx.com, a bit confused on what I would need to get

I haven't decided what to get if white or multicolor, is for a kitchen under counter. Is there an idiots guide on how to decide what I will need or if anyone that knows better can guide me what will I need to get a working strip for under €20

White Strip looks like ready to go with a EU plug.

Blue Light What would I need to get extra with it?

Also seen LED with mini controller I see they have 12V as Rate Voltage does that mean I just need an adapter?


Thanks

Could anyone suggest where I could pick up LED lights that have b22 connections? I'm looking at replacing all my cfl bulbs (around 12). The only ones I've seen that were reasonably priced were 'Source' LED golf ball shaped ones (470lm, 5.2W) at €6 a pop in my local electrical shop. The next priced one was 9.50 for a normal bulb shape, 9W I think?

I'm planning on buying for myself and my parents house, so roughly 35 in total, but if they're that expensive I might just get them for myself, or just leave them.

Also, has anyone any reviews on LED light panels?, the non recessed ones. The guy in the shop didn't really know what I wanted when I tried to explain it to him. It's an idea I had for a room that's quite dark after an extension was built.
Thanks.

Hey Sparkies, I am getting ready to put in my kitchen, I have chased the walls, but was thinking would I be able to get under counter sockets, the upper cabinets can hold the socket-I was going to suggest to my sparky, to just use surface mounted boxes, they won't be seen then unless you look under the cabinet-I don't like looking at sockets on the tiled wall/backsplash.

I know they do under cabinet strips in the usa, but don't know how it works here-thanks in advance

Just finishing off replacing my bulbs from kitchen/living/sitting/shower rooms and hallway, originally had a mixture of CFL and halogen spots (which
were themselves replacement of 'ordinary' bulbs), 15 bulbs in place totalling 500w. Now have 37 LED spots in place, some of the fittings were expensive in kitchen and shower room but my total is now 66w as most are 1.2w with just the odd 3w or 5w for over counter preparation and dining/homework table. Fitting and cabling bought locally, all the prep work like positioning and drilling done myself and sparky for wiring up, bulbs from Amazon as no local electrical shop could supply at the low wattage I wanted.
Result is a 67% saving in running costs, if they are on an average of 15minutes a day each I save €72/year, half hour brings me up to €143 etc.
Best decision I made was putting loads of them in, I've seen places where folk only replaced halogen with LEDs and the place is just not bright enough.
If on the fence, do it. Payback should be circa 2 years...

Bruthal

To save 75 euro in a year you would need to be running the 66 Watt load for over 2 hours a day instead of the 500 Watt load by the look of it.

15 minutes a day gives 8 euro saving. Although I might be missing a digit somewhere.

€7.50 perhaps rather than 75?

I replaced 13 x 50w halogen with Osram dimmable 5.3w LED's a few weeks ago and they are actually marginally brighter than the halogens that they replaced, I was very surprised... I always thought the light wont be as good, but so what you are saving a huge amount of power, you cant have your cake and eat it, turns out you can...

Yep you're correct, too much DIY and not enough Excel, chances are the savings will be hard to predict as different areas of the home use lights at different time, kids are always leaving on the hallway lights after going to bed so they could have been on for 2hours each night burning 300w and now they'll only be burning 7.2w so that's a €8 saving in itself.
Whatever about the maths it's certainly a saving and payback will happen...

If you want quicker payback you could switch them on for longer.

Wait a minute...........

I've tested a number of GU 10, G9 and T8 bulbs over the past two years or so. From cheaper bulbs to more expensive bulbs. I think I've had a bulb stop working from each batch at this stage (Philips, Osram, Auraglow, Sebson, no-name etc.). Very disappointed overall.

Could it be that I've had a run of bad luck? Bulbs were installed in three houses and one office.

Adrian J Lynch

could you recommend a good 12v led lamp for a bedroom light.

Thanks

Perhaps. I bought 15 Philips 8W dimmable Master LEDs a year ago and, at €25 a pop, thank f**k none of them have failed yet.

I have 13 or 14 philips 4w led in the house for at least 3 years, none have gone yet...

Can anyone recommend some "warm" non-dimmable GU10 LED bulbs.

I put some Phillips 5w in the kitchen and they are perfect but looking for something a little warmer for the hallways and other living areas

Budget €5 -€10 per bulb

I see that the Philips core led 4.5 w is now giving 345 lumens at 3000K A big increase in the 180 they had before and the 270 lumens on the market last year.

These are non dimable would fit that price range and are available in warm white.

Note that the warmer many of these lamps are, the less lumens available. That's why early ones, and street light leds look a little cold and blue, to max the output.

How would those lumens compare to a 50W 12v halogen do you think?
I need to swap out a few spots for my brother and he doesn't need dimmable

Not as good 12v can get 600 to 900 lumens
