Tennis court lighting

[HES2019]

Good afternoon all,

I have been asked to quote for an LED lighting upgrade to 2 x outdoor tennis courts. The existing metal halide lights are mounted on lamp posts, 6 per court. Could someone please advise on an appropriate amount of lumens per LED light and any preferred brands?

The tennis courts are for the local village community and are only really used in the spring and summer months.

Thank you in advance

What wattage/lumens are the existing metal halides? Surely If they are happy with them you would want to match them as closely as you can. Remember metal halides are a much wider spread of light than leds so that's something to check, don't want dark spots running after a tiny ball.

I am sure there must be guidance on a tennis court blog or installers web site somewhere.

If you are lucky you might be able to get an LED manufacturer / supplier to specify suitable fittings. If you can identify the existing fittings and/or installation positions, their applications engineer might be able to use their photometric data and CIBSE recommended levels to work it out exactly.

Not sure about England but here Bell with come out and design your lighting and tell you what you need for your requirements if you commit to buying their product, not sure if there is a minimum limit on this though.

They also have a convenient lighting design calculator available online, but not much help to the OP as it doesn't include this type of installation.

As others have said there are companys that will design for you . Call your wholesaler you normally use and they should be able to recommend one. Just to add you want to check what is used In the bottom of the post to terminate the cables. I've seen a lot of bodge jobs with poor detracted connections.

I'd say they are around 250W MH's, they are fairly low grade courts and not used all that much so it doesn't need to be like a professional club court in terms of lighting, just enough for a few hours of play on the odd evening.

I've been digging around but it's surprisingly hard to find UK based articles/info

Yes spoken with CEF and they have recommended the below, however I don't feel 100W x 6 will be sufficient, I shall contact a manufacturer for a lighting design and take it from there.

Have a look at these, i think you will be up at the 150 - 250W range..

Don't trust what cef staff say, in my experience their knowledge is incredibly poor and they really don't care, ask them if any of the vrands they sell offer a design service also if your struggling.

Don't just speak to the man behind the counter You need a lighting designer to go out and do a survey. Cef should be able to recommend one so they can sell you the lights . You will need to know is the tennis court going to be use for torlements. As this will demand specific light level.

I was going to say that probably 150W LED is closer to 250W MH but also agree with Lucian that light coverage needs consideration. It might be better to put in 2*75W or similar at each point so the beams can be spread a little.

Simultaneous switching is no more onerous so existing set up should be fine.

Save on energy costs and buy glow-in-the-dark balls

What about ladies tennis?

 

[DPG]

Bit over priced those court lights. It's a bit of a racket

 

[Mike Johnson]

Yes I think tennis players are strung along a bit, they should be gutted at the price.

Don’t you just “love” tennis puns….

They have an "advantage" over other puns!

 

[sparkonetwo]

can you not do the calculation yourself? surely if it's legal for you to do this type of work, doing the calc should be a breeze, shouldn't?

Not a particularly helpful first post on a forum.

Maybe the guy isn't used to working out lighting patterns and beam spreads for large outdoor areas - it's not a particularly common day to day job.

Minimum illuminance for recreational tennis: 300–500 lux (≈ 30–50 lumens/sq.ft) per court.Total lumens per court:
Court size: ~2,800 sq.ft (double court, 36m x 18m).

Total needed: 84,000–140,000 lumens (30–50 x 2,800).

Per fixture (6 poles/court): 14,000–23,000 lumens per LED (assuming even distribution).

 

[bigspark17]

If it were me id ask how many lumems they require on the playing surface, map out the poles on a diagram with size of playing surface and pole heights then take this information to a lighting specialist and they will do these calculations for you and give you a spec.

You nned to look at the flicker rate as with fast moving balls it is quite important.
