The Astro LSC4W350LRP LED Driver is a compact constant-current driver from Astro, designed to convert 100–240Vac mains into a regulated 350mA DC output for compatible LED fittings. The model designation and technical details are printed on the housing and the unit is intended for integration into small luminaires and confined installation spaces.
Its form is an ultra-compact rectangular white plastic housing with integrated mounting tabs and two screw-hole cutouts for surface mounting. The unit is purposefully small to allow discreet installation inside slim or shallow fixtures and enclosures. Available mounting and wiring arrangements suit tight installation envelopes.
The driver is built with clearly colour-coded wiring: blue and brown for the PRI (mains input) and red and black for the SEC (DC output). It delivers a constant current of 350mA with a power range of 1–3.3W, making it suitable for LED modules and fittings specified for 350mA within that wattage range.
Regulatory marks on the casing include CE, SELV, ENEC 05 and double-insulation symbols. The unit is rated IP20 and carries a three-year warranty. The technical label confirms universal 100–240Vac input. Dimming compatibility is not specified on the label; consult the manufacturer or Lighting Design Online for dimming requirements and compatibility with specific dimmer types.
As lighting designers we recommend checking the lamp load and thermal conditions when specifying compact drivers. Use our driver calculator to confirm quantities per driver and refer to the product label for wiring identification. For projects that require UL-listed components for North America, consult the manufacturer’s regional range.
Lighting Design Online supports this product with considered, project-friendly guidance and clear installation information so you can specify with confidence. The emphasis here is on getting the right outcome: a compact, certified driver that fits the luminaire, meets safety marks and gives predictable performance in small-scale installations.
