The driver maintains a stable 900mA current across connected LED loads, regulating output despite small input voltage fluctuations and ensuring consistent brightness across the fixture's rated lifespan. The 1-10V dimming interface accepts analogue control signals from compatible dimmer modules, allowing light intensity to be reduced from full output down to approximately 10% of maximum.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial, retail and hospitality installations where larger LED panels, downlight arrays or linear fittings need centralised power regulation, the driver fits inside ceiling voids, suspended track housings and metal luminaire bodies with a minimum 43mm depth clearance. The 150mm length and compact rectangular profile allow it to be mounted parallel to linear LED strips or positioned remotely from the light source with cable runs up to the driver's rated capacity.\u003c\/p\u003e\n\u003cp\u003eThe white plastic housing carries an IP20 rating, making it suitable for dry indoor environments only — ceiling voids, back-of-panel cavities, above false ceilings in offices, retail spaces and hotel corridors. Built-in thermal protection reduces output current if the driver's internal temperature exceeds the safe operating threshold, preventing component damage during sustained high-load use. Over-voltage and short-circuit protection isolate the output if a wiring fault is detected, protecting both the driver and the connected LED fixtures.\u003c\/p\u003e\n\u003cp\u003eThe driver operates on 220-240V mains input and converts this to the regulated 900mA constant current output required by commercial-grade LED modules. The 5-year warranty covers failures due to manufacturing defects under normal operating conditions.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength (mm)\u003c\/td\u003e\n\u003ctd\u003e150\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection (mm)\u003c\/td\u003e\n\u003ctd\u003e43\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimmable\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e5 Years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does constant current mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eConstant current drivers regulate output by maintaining a fixed current (900mA in this case) rather than a fixed voltage. This matches the requirements of LED modules, which need stable current to produce consistent brightness and avoid thermal damage. The driver automatically adjusts its output voltage within its rated range to maintain the 900mA current as the LED load changes with temperature.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does 1-10V dimming work?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe driver accepts a low-voltage control signal between 1 and 10 volts DC from a separate dimmer module or control system. A 10V signal produces full light output, while a 1V signal reduces output to approximately 10% of maximum. The dimmer module is sold separately and must be compatible with 1-10V analogue control protocols.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it be used outdoors or in bathrooms?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The IP20 rating means the driver has no protection against moisture ingress and must be installed in dry indoor locations only. For bathroom or outdoor LED installations, an IP65 or IP67 rated driver is required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat LED fixtures does it suit?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe driver suits any LED module or fixture rated for 900mA constant current operation with a total wattage up to 45W. Check the LED fixture's specification for its current requirement — it must match the driver's 900mA output. Voltage compatibility is less critical with constant current drivers, as the driver adjusts output voltage to maintain the 900mA current.\u003c\/p\u003e","brand":"Ideal Lux","offers":[{"title":"Default Title","offer_id":45732936450315,"sku":"220802","price":132.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/220802_WEB001_BASIC_DRIVER_DALI_PUSH_45W_900mA_79313cb5-8234-4a44-882f-06be6d6e5f21.jpg?v=1724709483","url":"https:\/\/niori.co.uk\/products\/radiara-45w-constant-current-dimmable-led-driver-900ma","provider":"Niori","version":"1.0","type":"link"}
