Collingwood H2 Pro 550 DLT35660NW Brushed metal 4000K Dimmable, fire-rated downlight


Our H2 Pro 550 features more innovative upgrades for ease of installation and reduced running costs.
A slimmer profile allows for easier installation, plus at over 100lm/W this is our most efficient downlight yet.
These updates are in addition to the typical H2 Pro quality and features you can depend on; fire-rated, dimmable and available with our seven-year extended warranty.
With a choice of two beam angles - 38° and 70°, 11 interchangeable bezel options (four of which have paintable finishes) and an IP65 rating, this downlight is the ideal choice for lighting any room, anywhere.
For a quicker, easier and more secure installation, try the 'T' connector version. With all the benefits the H2 Pro 550 has to offer and more, the H2 Pro 550 T LED downlight cuts installation time down dramatically. By using a loop in loop out push-fit terminal connector, not only will you save time but you will find it easier to install using no tools as compared to more traditional screw fit or ratchet connectors.
Suitable for both new and retrofit installations and includes an adaptor for both UK and EU cable dimensions.
