Collingwood H2 Lite Downlight 4CCT White DLT551500B

Collingwood DLT551500B H2 Lite CSP — Wattage & CCT Switchable Fire-Rated LED Downlight, IP65

The Collingwood DLT551500B H2 Lite CSP is a versatile fire-rated LED downlight designed for flexible residential lighting installations. Featuring switchable wattage (4W or 6W) and switchable colour temperature (2200K, 2700K, 3000K and 4000K), this advanced IP65-rated LED downlight allows installers to choose both brightness and light tone during installation to suit a wide range of rooms and lighting schemes.

Delivering up to 780lm output with efficacy up to 145lm/W, the H2 Lite CSP provides energy-efficient illumination while remaining compatible with TRIAC mains dimmers, including both leading and trailing edge dimmers. The fitting is also suitable for Bathroom Zone 1 ceiling installations, making it ideal for bathrooms, kitchens, hallways and modern living areas.

Flexible Lighting with Switchable Wattage & Colour Temperature

This switchable LED downlight provides excellent flexibility for installers and designers. Front-mounted switches allow both wattage and colour temperature to be selected during installation without removing the luminaire.

Choose between 4W or 6W output depending on the required brightness, and select from 2200K ‘Ember Light’, 2700K warm white, 3000K warm white or 4000K cool white to create the desired ambience. The 2200K Ember setting helps reduce blue light and creates a cosy, warm atmosphere similar to soft fireplace lighting.

Fast Installation with First-Fit Connector

Designed with installers in mind, the H2 Lite CSP features a 2-part first-fit connector that allows wiring to be completed while the luminaire remains detached. This enables convenient loop-in/loop-out wiring and easier maintenance when reconnection is required.

The fitting also includes large lever terminal blocks with testing ports, helping electricians complete installations quickly and safely. Compatibility with Click Flow CT100 connectors further improves installation efficiency.

Fire-Rated Protection and Bathroom Safety

The H2 Lite CSP helps maintain ceiling fire integrity with tested ratings of 30, 60 and 90 minutes in solid timber ceilings, along with 30 minutes in I-joist and metal web constructions. Its IP65 rating from below protects against moisture and splashes, allowing safe installation in Bathroom Zone 1 ceiling areas.

With Class I electrical protection and compliance with UK Building Regulations Part B, C, E, P & L, the fitting provides reliable safety and long-term performance.
