The driver maintains stable 500mA output across its operating range, preventing flicker and extending LED lifespan by eliminating current fluctuations that degrade LED junctions over time.\u003c\/p\u003e\n\u003cp\u003eMeasuring 110mm long by 52mm wide with 150mm input and output cable tails, the driver fits inside ceiling voids, behind panels and within light fittings where space is restricted. It operates on 220-240V mains input and includes thermal shutdown and short-circuit protection to prevent damage if the output is accidentally shorted or the driver overheats. The IP20 rating suits dry indoor locations including ceiling voids, wall cavities and cabinet plenums.\u003c\/p\u003e\n\u003cp\u003eThe 1-10V dimming protocol allows the driver to be paired with compatible 1-10V dimmers, reducing light output from 100% down to approximately 10% depending on the connected LED load. This analogue dimming protocol is widely used in commercial lighting control systems and interfaces with most building management systems. The white polycarbonate housing dissipates heat through ventilation slots on the top face, and the driver carries a 5-year warranty from Ideal Lux.\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\u003e110\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection (mm)\u003c\/td\u003e\n\u003ctd\u003e52\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable Length (mm)\u003c\/td\u003e\n\u003ctd\u003e150\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 maintain a fixed current output (500mA in this case) regardless of small variations in voltage or load resistance. This prevents LED brightness fluctuations and extends LED life by avoiding current spikes that degrade the semiconductor junction.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this compatible with standard household dimmers?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. This driver requires a 1-10V dimmer, which is a different protocol from trailing-edge or leading-edge phase-cut dimmers used in most UK homes. 1-10V dimmers are typically found in commercial lighting control systems and building management installations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it power multiple LED fittings?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, provided the total LED load draws 500mA at the driver's output voltage and does not exceed 21W total power. The exact number of fittings depends on the current and voltage requirements of each individual LED module.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhere can it be installed?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe IP20 rating suits dry indoor locations only.
