Zone one is the dry core, where the run gets measured and the cut points chosen
Confirm the footage on the beam with a tape, twice. Many strips can be cut at designated points and reconnected with compatible connectors or by soldering, depending on the product. Check the published interval and plan the run to land on it.
One option for a sheltered center position is EnoLED's UniBasic medium output tape, with its stated location suitability, watts per foot, tape width, CRI and cut interval verified first. Shop the outdoor lighting collection asking one question of each spot: what is it exposed to?
Zone two: the splash band along the open edges
Wind driven rain, splash and standing water are three different problems. An edge run sees water arriving sideways at speed plus whatever bounces off the boards. For that band a strip carrying a published IP67 rating, such as the Glow67 dot-less wet location tape, belongs on the shortlist, with the rating and sealing requirements read off the page.
Water rarely defeats the tape. It gets in at the cable entry and travels inside the sheath toward the driver. Leave a drip loop below every entry, and see our note on sealing a joint that will get wet.
Zone three: standing water, and the positions worth leaving dark
Post bases, step nosings at grade and any low ledge where a puddle forms are their own category. Immersion, even brief, is a different exposure from spray, and a rating that suits the fascia may not suit the ground. The answer is usually to move the run up rather than buy a higher rating.
Prep, dry fit, mounting, then power
Clean and dry the mounting surface: an exterior beam carries pollen, dust and old finish, and no adhesive works through that. Dry fit the whole run in its channel with nothing stuck down and nothing energized, then check from the yard that the line reads straight. Adhesive behavior varies by product and surface, so read what the manufacturer states and add mechanical fixing where the instructions call for it.
A channel gives the run a straight body outdoors and helps carry off the heat the tape makes in normal running. Behind a diffuser it reduces but does not guarantee the loss of visible dots; LED density, the channel depth and the diffuser fitted over it count for as much. No channel is mandatory.
Now mount, and only now wire. Every run goes back to the driver in parallel, never chained one into the next. Once those lengths are set, size the supply from the power supplies stocked at LED Club: published watts per foot times installed footage, then 20 percent or more of current headroom, both verified. If the published figure is 3 watts per foot and the patio takes 22 feet, that is 66 watts, and 20 percent on top puts the driver at 80 watts or more. Take the watts per foot from the product page, not from that example. One number governs the assembly: tape, driver and control all stating 24V.
Nothing outside gets wired until the breaker feeding the patio is off at the panel and confirmed off. Exterior receptacles, the junction box a feed lands in, outdoor rated boxes, in-wall cable, a switch or dimmer box indoors, and any hardwired driver belong to a licensed electrician, whose work follows the NEC where it applies, local electrical code, and the manufacturer instructions for each device. Do not put a meter on an exterior line voltage conductor. Read nothing here as permission to work on the 120V side; that comes from a license, not a page.
