outside lights - up lighting trees

[brman]

got a job to put in some outside lights and it turns out the guy wants a couple of lights lighting some trees from below. He is after soft lighting so I was thinking some diffused CFL spots but I've never done ground mounted lights before.

Is IP44 good enough or do I need to go higher for ground mounted stuff? Are there specific mechanical requirements for ground lighting?

What about cabling? I was already planning SWA underground from the house but was originally planning flex (NYY-J?) from that to the lights. Now I am not sure the best way of cabling to the ground mounted lights as I guess flex is likely to be damaged. swa all the way? it could be a pain to get underground to where he wants the lights because of tree roots......

PAR38 spike lights. you can get different colours. the actual fitting is IP rated but designed for flex cable. you would need an adapt, box to connect to SWA.

thanks tel. So they are designed to be on a flex and just stuck in the lawn somewhere?
Lets say it has a couple of meters of flex to the adaptable box (or even a outdoor socket??) does the flex need to be mechanically protected in some way? I am a bit concerned with flex just lying on the lawn or in flower borders.....

you could fit about 2ft. of bright coloured arctic flex from the ad. box to the light. it's possible to get 1.5mm SWA in the fitting, but no facility to gland it.

Always a problem this one, keep the flex as short as possible as you suggest, would be nice to give it some mechanical protection - but what do you use, if it's buried a spade will be through it in no time, personally, I think it's better on the surface, at least the gardener can see it.

Could maybe use some steel copex (cant remember the technical term for it) and cover the flex up to the back of the light and then fix it to the adaptable box?

I assume these trees are quite small, if larger I've used 70W metal-halide floods - can get different colours as well.

Thanks Guys, I'll talk to the customer about what he wants protection wise. Bright coloured flex might be the best if he doesn't mind that. At least with the spikes they are easy to move when he mows the lawn!

Trees are probably about 40 foot high but the garden is reasonably small (about 50 foot square) so he doesn't want too much light dominating the area. I'll probably buy one light so he can try it on an extension lead to check whether it is what he wants before we commit to the swa etc.

you could always use a bit of sy cable from box to fitting,gives a bit more protection.

 

[brman]

Thanks Phil, I have not come across SY cable before.

however looking at sycable.co.uk it says "With the right protection (such as keeping it out of direct sunlight), SY Control Cable is useful for outdoor installations. The SY Flex is most suitable, however, for work in dry or moist indoor environments.". Don't sound so good for what I want......

I would go for hi-tuff personally. Can be bent and glanded into a fitting but has impact resistance and being black, offers uv rating also.

You will probably need at least 70W MH lamp. It will be facing upwards so will need to be >IP55
I once used a 150W MH lamp on a 80ft+ tree. The neighbours thought it looked interesting !

you could use lewden sockets but these are around £40 a piece and plugs are extra BUT they are weatherproof

are you saying a standard IP66 rated socket isn't weatherproof?

 

[mogga]

sometimes not with pulg inserted they arent need to watch what your buying
