Fick fram det här: For maximum light output you can choose to upgrade the 3w white LEDs to Cree XPG 6700K chips. The 15w blue and 30w white and 1w violet chips are still Semi Chip LEDs. While giving a height light output the Cree LEDs also have a somewhat more yellow colorcast, around 11000K to 12000K when all chips are lit and around 6700K when only the 3w chips are lit. Customers are advised to consider this, together with the higher price of the Cree chips before ordering. Min rödfärgning. 15 wattaren är alltså inte Cree utan Semi - det betyder då troligvis att peak våglängd inte är Cree:s Se här på 3 wattarna royal blue MVH Lasse
