DL4 LED Down Light

LED Down Light

Precision machined LED lighting fixture with 100-277V Integral Driver LED or COB LED (remote driver required). Can be used for ceiling mounted down lighting in interior or wet location applications.

  • Body and cap available in round and square (aluminum only) shapes.
  • Thick walled cap and optimized high temperature silicone O-ring placement prevents leaking.
  • Patented ‘double-taper’ locking knuckle that locks and stays locked.
  • Thick walled cap allows for more threads and larger set screw to prevent stripping.
  • Field replaceable and feature replaceable lenses.
  • Integral Driver LED option utilize dynamic transformer recognition to simplify installation and patented LEDSense® thermal management to keep LED running at the optimum temperature.
  • COB LED option uses industry standard components to simplify future upgrades.

    Mount Canopy:

    Available with the following mount options: MO3(Machined Round Canopy), MO15 (Machined Square Canopy), and MO12 (Surface Mount Canopy). MO3 & MO15 mount options come mounted to a steel universal mounting ring for ease of mounting and adjustment on an industry standard round junction box. See mount specification sheets for more information. (Mount canopy must be mounted to an appropriate ceiling or junction box, in such a manner that is capable of holding the weight of the fixture. Junction box and hardware not included).


    Machined 6061-T6 aluminum or C36000 brass body and stem (if specified) are permanently attached to canopy using a 304 stainless steel threaded nipple.


    Machined cap locks in place with one 18-8 stainless steel set screw, and is sealed to the body with a high temperature silicone O-ring. Square caps feature removable and field interchangeable cutoffs.


    TGIC thermo set polyester powder coat paint available in 14 standard colors. On aluminum model, finish is applied over a corrosion resistant, hexavalent chromium free,RoHS compliant coating. Aluminum model available in one additional metal finish: Clear Anodized. Brass model available in three additional metal finishes: Natural,Polished, and Aged.


    Tempered, clear lens, secured to cap with a high temperature, UV curing, silicone adhesive.

    Light Engine:

    Integral Driver LED: 100 to 277 VAC (50/60 Hz) input, 20W max. power (17W@120V, 20W@277V). LED lamp features: integral driver, 1280 lm max output, 75 lm/W max efficacy, field changeable optics (15º, 23º, 35º & 51º), push button selection of light level (100%, 80%, 55% & 18%), 120-277V 0-10V dimming available at three highest (100%, 80%, 55%) light levels, 120V phase dimming at highest (100%) light level (see Dimmer Compatibility List), an L70 of 60,000 hrs., and patented LEDSense® thermal management to ensure reliability and lumen maintenance. Note: thermal management system may cause power input and light output to vary slightly depending on fixture material, orientation, lens accessories, mounting, and ambient temperature.

    COB LED: COB LED package uses modular industry standard components to simplify future upgrades and includes features like: performance of 1800 lm, 16W max input (@350mA) or 2400 lm, 21W max input (@500mA), field replaceable optics (12º, 25º, 40º & 60º), and an L70 > 55,000 hrs. Note: requires Vision3 approved 350mA or 500mA constant current driver mount.


    CSA tested & certified to US and Canadian safety standards (UL1598) for wet location ceiling use.

    Integral Driver LED:
    Integral driver LED available in all configurations.
    COB LED:
    DL4A - 500mA max driver current.
    DL4B - 350mA max driver current.
