Description

The Radiara is a 31W constant current LED driver delivering 900mA output with 1-10V dimming control, housed in a white plastic enclosure measuring 150mm long by 43mm wide. It converts mains voltage to stable constant current output suitable for LED strips, downlight arrays and panel lights requiring consistent 900mA current regulation.

Designed for indoor commercial and residential installations where dimming control is needed, the driver pairs with 1-10V control systems common in office lighting, retail display lighting and hospitality environments. The 1-10V protocol allows the driver to be controlled from wall-mounted dimmer switches, lighting management systems or building automation controllers. Output current remains constant at 900mA across the full dimming range, preventing colour shift and flicker as the light level changes.

The IP20 rating limits the driver to dry indoor locations — ceiling voids above offices, behind retail display panels, within kitchen cabinet lighting runs. The compact 150mm x 43mm footprint fits into shallow ceiling voids and narrow cabinet runs where larger mains-voltage transformers would not. Thermal protection shuts the driver down if internal temperature exceeds safe operating limits, automatically resetting once the unit cools. The driver carries a 5-year warranty covering component failure under normal operating conditions.

Frequently Asked

What LED fixtures does this driver suit?

Any LED fitting requiring 900mA constant current input and up to 31W total power. This includes most commercial LED strips rated at 900mA, downlight arrays wired in series, and panel lights specifying constant current drivers. Check your LED fixture's data sheet for the required current — if it states 900mA, this driver is compatible.

What does 1-10V dimming mean?

1-10V is a control signal protocol where a separate low-voltage cable (typically 2-core) carries the dimming instruction from a controller to the driver. At 10V the driver outputs full brightness; at 1V it outputs minimum brightness (typically 10% of full output). The control cable is run separately from the mains supply and connects to the designated 1-10V terminals on the driver.

Can it be installed in a bathroom?

No. The IP20 rating provides no protection against moisture or water ingress. The driver must be installed in a dry indoor location such as a ceiling void, cupboard or behind a panel where it will not be exposed to steam, condensation or water splash.

Does it need ventilation?

Yes. The driver dissipates heat during operation and requires free air circulation around the housing. Do not install in a sealed enclosure or tightly packed cavity with no airflow. Allow at least 20mm clearance around all sides of the driver body for natural convection cooling.

Shipping & Returns

Free worldwide delivery

Free worldwide delivery on all orders over £99. International orders for third-party brand products may be subject to an additional courier surcharge based on volumetric weight, particularly on larger lighting fixtures — if a surcharge applies, our team will email you with the amount before dispatch and you can proceed or cancel for a full refund. See full delivery terms.

Returns

30-day returns window from delivery. As all our products are electrical or lighting goods, returned items must be inspected and recertified by a qualified electrician before resale — the cost of this inspection (25–40% of the item value) is deducted from your refund. Customers pay return shipping. Made-to-order, special-order and clearance items cannot be returned. See full returns policy.
