Dimmable Hydrus 4ft Single LED 19w Non-corrosive Fitting 3-CCT

Introducing the Dimmable Hydrus 4ft Single LED 19w Non-corrosive Fitting - CCT (Part number: 500021-DD), the most advanced Dimmable Switch Dimming & DALI/DALI-2 Dimmable 4ft Single LED IP65 Batten Fitting available that redefines the way you illuminate and control your space.

The primary feature is its Push Dimming (also known as Switch Dimming or Push-to-make Dimming) and DALI Dimming functionality, depending on your lighting requirements. This is the most versatile high-powered 4ft Single LED Batten on the market.

Switch Dimming, also referred to as Push Dimming, whereby you control a smaller series of LED Battens or a single Batten with a retractive dimmer switch. A single push turns the Batten(s) on/off like a normal lighting fitting, but has the ability to dim the lighting levels via the same switch when held down. These are usually a spring-loaded switch that returns to the centre when released. They can also be referred to as a momentary switch.

Just make sure you install a Switch Dim/Push Dim 'retractive' dimmable switch if this is your chosen setup. You also need to be aware that the driver needs a permanent live, switched live (from the retractive switch), earth and neutral. Therefore, requires more wires than a standard fitting. Please note: Mains TRIAC dimmers will NOT work with this light fitting. 

DALI, which stands for Digital Addressable Lighting Interface is a 2-way communications protocol which allows you to communicate and control components in an advanced lighting system. This Dimmable Hydrus 4ft Single LED 19w Non-corrosive Fitting - CCT can also be used in advanced DALI lighting systems as well as Switch Dim setups. This batten is manufactured using a Helvar LL80HE-DA-100-800 Dimmable LED Driver which delivers this unique flexibility to operate both dimming functionality.

There are 2 types of DALI interface, the first being the original DALI IEC60929 interface from the late 90s and the more recent DALI-2 IEC62386 which was introduced in 2020. The Dimmable Hydrus 4ft Single LED 19w Non-corrosive Fitting - CCT can be used in both systems. However, if you are unsure about your setup or you'd like to ask us a question before ordering.
