LED lighting

[PIP IOM]

i've got a job where the customer wants to utilise LED downlights not halogens.

Kitchen and bathroom and they want bright white light 50w halo equivalent

I'm an LED virgin so firstly:

is this possible

what is the ratio of max wattage LED to Halo

I've got the Intalite UK catalogue (CEF) and Aurora (Wallsall) my only 2 on island suppliers of note and they look quite expensive.

which are the best on-line sites for reference, prices etc

LEDs are expensive to buy but to offset this they are cheaper to run, if you are using normal downlighter fittings you will need to use the proper LED driver for them and not a transformer.

cheers so if you had say 6 x 50watt halos in a bathroom how many LEDs would you need to give equal bright light

It would depend on what LED lamps you used, there is a huge difference between all the makes and models with wattages and colours etc...

Depending where you look anything from 2-6W or so is equivalent to 50W of halogen lighting.

so if i put in 6 6w recessed should give them a good white light bathroom

That would be quite likely.

You need to be careful about lighting levels. A lot of comparative data re. LED lamps is by using the lumens directly below the fitting. Where they lose out to other light sources is the peripheral lighting levels away from the centre of the fitting.

This is a problem I had with some cheap lamps, they were more like lasers and were very good directly in front of the lamps. I used them for secondary and accent lighting but they were useless for main lighting sources. Not had a problem with non-cheap lamps, but then I could be lucky (doubtful).

Ideally you want to go and have a look at some lamps or grab some for yourself to see what they're like.

Far easier to look at the photometric data from the lamp/fitting manufacturer.

Assuming it's accurate, and also you can get a better idea of what it means by grabbing a lamp and powering it up. If your wholesaler is any good then getting some lamps for evaluation purposes shouldn't be a problem.

I was shown some 6w LED's (GU10 base - 230v), they cost something like
