You rarely need to use this, only when customer wants to save a few bob on fittings and still maximise lighting.

I had a shed load of questions on this from my 2330. Would have to dig it out for you though.

i have loads of questions , and i have no problem working them out, its just he said that i would be able to get the light levels of certain places/areas on the internet. i.e sports halls, theatres etc. but thank you . and if you know where to get the light levels a double thank you. cause then i can check lights and work out how many i would need in certain areas etc..

If you're serious and have a few bob to spare then the CIBSE website is a good place to have a look round.

CIBSE > Bookshop > SLL Lighting Handbook

This is most done at the design stage in any big project. All you need to do is follow the drawings and do the installation.

design and install could be the future

CIBSE guide A also gives general guidance on illumination levels, but wont be any use to you apart from that single table. Your best bet is like what Lenny says and get the SLL code for lighting if you are seriously interested in this. I have both of these books and can maybe help you if you need any illuminance levels.

cheers mark80 yeah the up to date illuminance levels would be great as it was only that table i was interested in at mo.. and i would be interested in that handbook sometime in the future . im only starting level 3 at end of august.. so just have the formulae to work out and dont know what else would be in that book.. thanks
