Im just about to replace a water-damaged ceiling after having a new glass fibre flat roof (now with a slope!) on an extension 5.2m x 4.3m.
We have been costing up LED downlights - 3 rows of 4 on 2 circuits /switches, probably dimmable. At present we have 2 sets of 3 x 40w and boy, does it show the consumption on my monitor!
After reading several threads most people seem to be against downlights, but quoting 50w per light which is obviously using halogen and just as expensive to run as ordinary bulbs. Ive been researching LED 4W or 7W, cool white - more expensive to buy initially but much cheaper to run. But how much light do the give? Our plan is to have either all 12, 8 or 4 on, depending on usage of room.
However im not too sure of building regs - if fitted with LED and not halogen, do they still have to be in enclosed, fire rated fittings or can LEDs be fitted in the cheaper non enclosed fittings - tho it might be wiser to be safe anyway.
The gap from ceiling to roof is 175 mm and we are putting in 50mm insulation board (as we discovered insulation was almost non existant!)
To a certain extent lighting is down to personal opinion, but lets have some proper spec quotes or advice between halogen and LED. Not just wattage, but also the light spread and other ratings etc.
any help with regs appreciated!
