...yeah man, that light is just a common, multi-bulb bathroom vanity fixture that can be found in any home improvement stores you have over on your side of the pond, we have Lowes and Home Depot over here but there must be some equivalent in the UK, ...another option is either a discount builders supply or a builders salvage yard where you can find some really nice deals, especially if you're not afraid to do a little tinkerin', lol.
...that one pictured is one of 4 i bought at a local discount builders supply house for $4.88USD each back about 5 or 6 years ago so even at full retail you shouldn't have to spend more that $20.00 - $25.00USD, ...i don't know what that is in pounds sterling, lol, ...or euro's either for that matter!
...if you find a builders salvage yard you can find some awesome deals on used HID fixtures and even T5's and other fluorescent fixtures, ...some might need work but working on lights is relatively easy if you have any knack at all and can follow directions and a simple wiring diagram, believe me it ain't all that complicated, lol.
...there's no telling what a dedicated stoner with an abiding need can accomplish!
peace, bozo
