Re: Anybody tried the Warm White (>90 CRI) Luxeons
From my website, comes the following:
This is the long-awaited 1.2 watt "warm white" Luxeon Star /O LED, now being sold by such outfits as ledsales.com.au out of Australia. (They ship all over the planet, so don't let their location throw you off).
The /O means the LED comes with an acrylic optic, mounted to the Luxeon Star PCB using a cylindrical black plastic spacer. This convention follows other Luxeon products, so if you see a /O after its name, it comes with the optic and mounting cylinder already in place.
The optic appears to be a NX01 type, so the LED inside is probably a low-dome (batwing) type. The phosphor appears to be a light, slightly brownish yellow, rather than the light whitish yellow you might see in cool white Luxeon Star LEDs.
This Luxeon Star is mounted to a square MCPCB (metal core printed circuit board), rather than the hexagonal board that other Luxeon Stars may be mounted to. This board measures 1.0" on each side, and has two notches in opposite corners so that it may be affixed to a heat sink.
The color temperature is significantly warmer (yellower) than most other white LEDs, probably coming in at around 3,000°K. Overall, this LED has a warm, yellowish white color to it.
The brownish color at the perimeter was caused by the camera, and is not at all present in the LED beam. The camera does not always do well for beamshots, and here is one example.
Measures 164,200mcd with a test current of 364mA.
This measurement is consistent with what I know about the warm white 1.2 watt Luxeons.
The bin number on this sample is MP4JW.
