Constant current LED drivers supply a fixed output current to LED arrays and modules regardless of input voltage variation, which is the correct driver topology for most discrete LED packages and high-power LED modules. The driver maintains consistent current delivery, protecting the LED junction from thermal runaway and degradation caused by unregulated current spikes. This makes constant current drivers the standard specification for commercial LED downlights, high bays, strip lights, and retrofit kits where the LED load is configured for a defined operating current.

When specifying a constant current driver, match the driver output current rating (typically expressed in milliamps, such as 350mA, 700mA, or 1050mA) to the LED array specification. Output voltage range, wattage capacity, power factor, THD, and dimming protocol (0-10V, TRIAC, or DALI) should all be verified against the fixture or LED board requirements before ordering. Enclosure rating (IP20 for dry indoor vs. IP67 for outdoor) is another key specification for outdoor or wet location applications.

Browse the complete LED Drivers category for all driver types. For strip lighting and tape LED applications, Constant Voltage LED Drivers are the appropriate choice. For life-safety and code-required emergency illumination, see Emergency Battery Back-Up Drivers. Multi-zone or tunable lighting systems may require Multi-Channel LED Drivers.
