Electrical Question

How do i change a single light to inset downlighters?

I would like to change the single central light in a utility room to a combination of three inset downlighters with about 1 metre seperation between each one. Unfortunately, I the joists are running the 'wrong' way, and the space is not accessible from above.
What is the solution to this problem? Is it too destructive so that I should abandon the idea?

Thanks to the guys who have come up with ideas/ comments and suggestions.

It's really helpful.

Well you certianly can't cut the joists! If possible, lift some floorboards in the room above the utility room so that you can establish the run of the joists and work out the centres. With this information you should be able to select three points at which you can cut holes for the fire rated downlighters to be fitted.

The spotlights must be "Fire Rated" see video clip and leaflet below;

downlighters have to be fited a minimum of 50mm from any joist, if you cannot acheive this you could fit them randomly, regards Terry.

The only sensible thing to do is reposition your downlights to suit position of joists. A joist detector would be helpful if you do not have access to them.

Hi, You should think about installing 2 brighter down lights or 4 less bright down lights therefore changing the spacing. You should leave at least 100mm between light and joist... Hope this helps.
