Osram Ostar 20 watt 6-chip LED star - warm white - tray of 60!

We need to clear these out, so we are giving a massive discount on sealed trays of 60 LEDs. They are engineering sample versions, but the same as the standard product.

These Osram Ostar LEDs have six warm white chips connected in series, just feed them up to one amp for several hundred lumens of warm white light (which may vary from 2500k to 3600k).

Because these are now obsolete, they are not as efficient as later model LEDs, but can be around 44 lumens per watt. Maximum current is 1 amp, or around 20 watts of input, so these MUST be used with suitable heatsinking!

Datasheet for these is here, part number is LECWE3B-PXQ4.
