That sensor is made by Apogee. If you software is up to date, then I think that it is probably OK with LEDs... you are just looking for a swag anyway. Even if it is off by 1/3, that is still enough quantity. If you are happy with the quality (I have no opinion on this), then stock away with some smooth and slow acclimation.
