After a bit of help if possible please guys.
I have to go and look at a job on Friday in a large hall where they want to run a table tennis club. no windows.
I have spoken to the club manager but not the table tennis people at the moment. The info i have at the moment is a white light and 500lux presummably at the table top. The ceiling is 16ft.
The hall is used for various activities including the local DODS doing various productions so i don't think i will be able to suspend anything much below the ceiling level.
I was thinking about low bay fittings, possibly one over each table depending on table spacing, but to be honest i have little experience when it comes to lighting levels etc.
Access for maintenance could be acheived via chains and a long flex through the ceiling from the void above which has walkways and access via stairs and the switchroom, so quite straitforward once they are installed.

This site may help you in planning the lighting:

http://tabletennis.about.com/o...de/a/lighting_room.htm

The International Table Tennis Federation guideline for tournament lighting is 3.02.03.04:

In World, Olympic and Paralympic title competitions the light intensity, measured at the height of the playing surface, shall be at least 1000 lux uniformly over the whole of the playing surface and at least 500 lux elsewhere in the playing area; in other competitions the intensity shall be at least 600 lux uniformly over the playing surface and at least 400 lux elsewhere in the playing area.


Most clubs tend to quote a lighting intensity over their playing tables of 600 lux.

Thanks for that, i'm googling round in circles at the moment trying to find levels for low bay fittings from 16ft and my wholesalers are useless. Judging by your post the 500/600 lux level is the general lighting level and they may require more over the tables. I will have more details Friday.

Several manufacturers will design for you - as long as you buy their kit. Philips come to mind - have used them for five a side pitches. Have a feeling Sylvania do likewise - Giggle is your friend.

In the first instance you will want to obtain guidance from the client as which other sports will be undertaken within the hall and the level of competitive play that will be undertaken. Whilst you have been specifically asked to look at table tennis some sports place far more onerous requirements on lighting such as badminton and cricket for example.

Once you have established this I would suggest that you have a look at the guidance from Sports England which will define the required lighting levels for various sports for the level of competitive play. (I am guessing we are talking about a local leisure centre so the requirements will be relatively low).

With regards to the lighting itself I would personally stick with 6 lamp linear fluorescents with multiple of the lamps 2/4/6 etc so that the lighting level can be easily adjusted to suit the sport and application which is being played. With regards to the fitting itself you want to be looking at something which is specifically low glare if you also need to contend with others sports such as badminton or cricket. I would keep well away from high bays / low bays as they have the potential to introduce significant glare and re-strike time will reduce the building flexibility.

Download yourself a copy of relux (it's free) and have a play.

You can soon get a design in there and play with different fittings and different levels. I had a similar challenge with some tennis courts a few years back and eventually found a really helpful chap at the LTA who could answer my questions about colour, lux levels and even suggested layouts for the columns to avoid glare.

Thankfully we didn't get the job as I'm even worse at tennis than I am electrics and there was always a chance of someone wanting me to play.

Here is the daddy of all lighting design, for you to read over the weekend, some nice drawings of a type that would be useful for an exam.
