The DLI Joule is built to high specifications – the second you pull it out of the box, you'll notice that it feels like a quality bit of kit. The Joule also comes with an array of impressive features and tweaks that make it stand out from the competition. For instance, the built-in spirit level ensures that the unit sits level once hung.

It may not seem like a massive issue to the untrained user, but the systems's angle will impact on the footprint to quite a high degree – even more so the higher the light is away from the canopy, so it's crucial that you get it right.
