About two months ago, I installed a set of Osram Xenarc 66340 CBB lamps that I bought at the Retrofit Source. Before someone jumps on me, they are NOT 7000K on the Kelvin scale as they say on the box. More like 5000K. They are just brighter than the previous Osram CBI version. This is from the Retrofit Resource LUX testing: CBB = 460 Lux, CBH = 415 Lux, CBI = 340 Lux, Standard = 315 Lux. They are working great in the stock adaptive housings on my 2013 LR4. As far as not being as bright as the LR3 housings.... I don't care!!!
