LED Over Cabinet Light - 300mm Length

Can you give me the total rise (height) of the unit when viewed in section as per fourth picture on details.
It goes upwards approximately 48mm.

I need to remove a wall light to fit a wardrobe. Can I use that spare supply to connect these lights
Yes but you will need to install a fused spur with a 3 or 5 Amp fuse to protect the installation.

Do i need an extension cable for each light, I need 3 lights
Each light has 1500 of cable that plugs into the driver, if you need longer than 1500mm buy the extension cable, if 1500mm is enough then just buy the 3 lights and 1x 6w driver.

I want 4 of these lights. How many drivers do I need, and if I want dimmers, do I need 4 of them?
The 15w driver can power 6 fittings, if they are all on the same circuit one dimmer would work.

Why do I need a driver for this light?
To power the LEDs, Wiring these direct to the mains will blow the LED chips.

The photograph shows the bracket in white , is this correct?
The bracket is silver and looks different because of the flash on the camera. Sorry for any confusion.

Which driver will I need for 3 of these over cabinet lights?
You will need PONSE40553 - 6W LED Driver with 6 Port JB4 Distributor

Is this & the associated driver/transformer safe for bathroom use?
This fitting is not IP rated, and therefore not safe for bathroom use. Please see our bathroom sections for fittings that are suitable.

How does the fitting attach to the wardrobe
There is 2 screws at the end of the fitting. This is flat that allows for a sturdy fix.

Is it possible to have these in warm white, 3K?. I`ve installed the warm under cabinet 24v LED lights and they are great. Had though this was available in warm too. But apparently not.
We have just introduced the warm white option, please see the product page for details.

Does this light run from mains or transformer ?
These require a LED convertor, if you go to the bottom of this listing you will see them listed below.

What is the price of a replacement lamp? Do you stock them as well?
No need, the LED chips will last for 30,000 hours - that`s around 25 years at 3 hours per day.

You state 'these LED over cabinet lights have a lead and socket that plugs into the power supply'. Am I correct in assuming the power supply you mention is actually the LED convertor?
That is correct, and they can be found at the bottom of this listing.

Does this unit come with a switch?
These are wired into your mains and have no independent switch.
