Weatherboard Packers – Easy Wall Light Installation No Matter the Weatherboard Gradient
Installing outdoor wall lights on weatherboard homes can be a time consuming and fiddly job - especially when the boards run on an uneven angles and vary in profile. At a practical level, it often means adjusting on the fly, shimming behind fittings, or risking a light that doesn’t sit parallel to the wall. It also brings aesthetic concern - nothing throws off a clean exterior design like a crooked fixture.
That’s where weatherboard packers come in. Designed, copyrighted and manufactured right here by our team here in New Zealand, these small, lightweight accessories help you mount wall lights on weatherboard cladding quickly, neatly, and with confidence - no matter the gradient of the boards beneath.
Why Weatherboard Surfaces Are Tricky for Wall Lights
Unlike flat surfaces such as brick or concrete, weatherboard cladding is designed with overlapping, angled profiles to shed water. That’s great for durability - but not so great when you're trying to install a light fitting that needs to sit vertically against the wall.
The sloped face of weatherboards means most wall lights will naturally tilt backwards unless you create a level mounting surface. Inconsistent gaps can also leave wiring exposed or allow moisture in behind the fixture. It’s one of the most common issues electricians face when installing outdoor wall lights on homes.
The Simple Solution: Superlux Weatherboard Packers
Superlux’s Stackable Weatherboard Packers make life a lot easier. Designed specifically for outdoor light installations on weatherboard cladding, these packers provide a flat mounting surface by compensating for the angle of the boards.
Made from durable materials and sized to suit common weather board sizes and outdooor lighting fixtures, here are some of their most valuable features:
> A stackable wedge shape - allowing you to adjust for gradients around 6°, 9°, 12°, or more, depending on how many you need.
> A knock-out section for easy cable entry, helping streamline your install without extra drilling.
> Trim-to-fit flexibility, so you can tailor the packer to different weatherboard sizes or tricky spots.
> Neutral colour matching, coloured to match the popular Dulux exterior colour double hasst, or simply paint them to suit.
Whether you’re installing a bulkhead, up/down light, or a decorative lantern, these packers help ensure your light sits flush, looks right, and performs reliably.
Designed with Installers in Mind
What sets the WBP145 and WBP110 apart is its focus on practical, time-saving installation. Instead of cobbling together makeshift wedges or carving custom shims on site, electricians can keep a few of these in the van and be ready for whatever gradient they encounter. The packers come into their own when mounting fittings that need to sit perfectly straight - like modern up/down lights or symmetric floodlights — where even a slight tilt is noticeable. And if you're replacing old fittings that were never quite aligned properly, using a WBP145 ensures your new installation looks clean, sits flush, and stays put.
Tips for a Clean, Professional Finish
Before installing, it’s worth checking the angle of the board with a level or angle finder — that’ll help you decide how many packers you’ll need to achieve a vertical face. Once stacked, they’re simple to screw or nail in place, and with the included cable knock-out, wiring is straightforward.
To complete the job, we recommend sealing around the edge with a weatherproof silicone to prevent moisture ingress — especially on exposed walls. If the packer edge is visible once the light is installed, a quick coat of matching paint will blend it seamlessly into the cladding.
A Handy Solution for Any Weatherboard Job
Superlux’s weatherboard packers are a simple but smart accessory that can save hours of frustration and deliver a cleaner, longer-lasting result. Whether you're working on a new build or refreshing the exterior lighting on a classic kiwi villa, they're the ideal companion for any outdoor wall light installation on weatherboard homes.
