    This listing is for a Panel of 6 COB Disks.
    Each Disk has 3 LEDs for a total of 18 LEDs.
    Output is Extremely
    Bright White.
    (6) 2.5 Watt LED Disks
    (Qty 1 Panel = 6 Disks)
    These LED Assemblies come in Panels of 6 Disks. Each ⅝" Disk has 3 LED Chips wired in series. Each Disk is electrically independent of the others. Typical operating current per Disk is approximately 0.20 Amps at approximately 12 VDC.
    Note: As with most COB (Chip on Board) LEDs, these should be powered with a current limited source to prevent thermal runaway.
    The panels have an aluminum substrate and the LEDs are insulated from the base. This allows wiring multiple Disks in parallel or series without having to seperate them. These 3x2 6-Disk Panels are cut from a larger 3x7 panel. If you order multiple panels, they will be cut from the same panel as a single assembly.
    Application / Test Notes
    We did not have the datasheet on this item so we bench tested them to evaluate their performance under several different conditions. Data is for one Disk.
    With a heatsink the recommended Maximum safe current is 0.25 A at 12.8 V.
    Without a heatsink we recommend an operating current of 50 mA at 10 V. The recommended Maximum safe current is approximately 75 mA at 10 Volts to prevent overheating. Even at this reduced current, the output at this current provides good bright white illumination.
    Ambient temperature, heatsink size and airflow will affect the actual safe power, but experimentally, with a good heatsink, the light output appeared to level off before 0.3 A. The difference between 0.2 and 0.3 Amps is not significant.
    We used a 3" x 5" x 0.75" aluminum block as a heatsink but that is overkill and depending on design and ambient air flow, you should get by with far less. We suggest keeping the Disk temperature below 150º F (65º C).
