Ultra Slim Under Cabinet Light

I want to install this type of light under a bathroom cabinet. What sort of switch can I use?
This type of light would be wired into your mains, and would use the current switch you have.

Do the lights require a transformer?
No this is a mains voltage fitting.

Please could you confirm the total depth of the fitting with the 7W lamp installed?
The total depth with a lamp installed in the fitting is 37mm.

Does the cable shown on the picture come out of the fitting as shown in the picture (at the rear) or from the centre at the top of the fitting?
The rear face of the fixture is not solid so the supply cable can be routed through the rear or out of the side to suit your needs.

I want to change my existing fluorescent lighting (under cupboards in our kitchen) to the ultra slim energy saving under cabinet lights. Is this possible, using existing wiring and also using existing mains light switch to operate them? I want to use 5.
Yes this should be fine so long as the existing wiring is in good order.

Can these be supplied with 9W dimmable lamps please?
The maximum wattage for this fitting is 7 watts. A dimmable version of the GX53 lamp is not available at present.

I only need replacement bulbs not complete fittings. Are these available?
