How should I add garden and outdoor lighting to my villa safely in the UAE heat?

Question

I want to light the villa garden properly — path lights along the walkway, a couple of spotlights up into the trees, and some lights around the pool area. Right now it's one sad porch light and a lot of dark corners.

Before I get quotes I'd like to understand what "done properly" looks like out here, because outdoors in the UAE is a harsh environment:

Is running new outdoor circuits a licensed-electrician job, or can a landscaper's handyman do it?
Does outdoor wiring need special protection (I've heard about earth-leakage / RCD for anything outside)?
What survives the UAE — the sun, the dust, and the daily irrigation water hitting everything?
Anything specific about lights near the pool?

Want to do it once, safely, and not be replacing corroded fittings every year.

Short answer: yes, it's licensed-electrician work, outdoor circuits must be on an RCD, and everything you buy needs to be properly weatherproof-rated — garden lighting fails in the UAE because people treat it like indoor lighting that happens to be outside.

Here's what "done properly" means:

Protection (non-negotiable): any outdoor circuit must be protected by an RCD/ELCB — outdoors you have water (irrigation, rain, pool) meeting electricity, so earth-leakage protection is what stops a fault becoming a shock. This is exactly why it's not a handyman/landscaper job.

Weatherproofing — the UAE killers are sun, dust and irrigation: - Fittings and junction boxes rated IP65 or higher (dust- and water-jet proof); anything less corrodes and fills with water. - Buried cable in proper conduit, at depth, on its own circuit run from the board — not surface cable a mower or a spade will find. - UV-stable, corrosion-resistant fixtures (cheap ones chalk and rust within a season in the sun and sprinkler spray). - LED throughout — low load, low heat, and a dozen garden lights can often share one properly-protected circuit (same logic as adding downlights).

Pool lighting is a special case: lights in or right beside a pool have strict low-voltage/isolation rules — that's specialist work, never a DIY or general-handyman job.

Common mistake: wiring garden lights off a random indoor socket with surface cable — it trips, corrodes, and it's a genuine shock risk in a wet garden. Get a licensed electrician to run proper outdoor circuits, ideally checking your board has capacity first. What IP rating and fixtures have held up best in people's gardens out here?

From the landscaping/finishing side: plan the cable routes before you plant or pave, because retro-fitting buried conduit through a finished garden means digging up what you just laid. Also think about where the irrigation lines run — you don't want cable and dripline fighting for the same trench, and you definitely want the electrical deeper and better protected. Getting the electrician and the landscaper to coordinate the trenching once saves doing it twice.

Not a villa but did a big planted balcony — even there the cheap outdoor string lights I first bought were dead within a summer from the sun and the odd rain. Switched to properly-rated fittings and they've lasted. The UAE sun is brutal on anything plastic and cheap outdoors, so whatever the electrician wires, don't cheap out on the actual fixtures — you'll just be replacing them and re-doing the connections.
