My SP33 has had a resistor change on the driver, see What did you mod today? - #4800 by djozz , and after that mod I sliced and fine sanded the 4000K 90CRI Samsung LH351D. The output is about half what a low CRI XP-L would put out, and the throw with a XP-L Hi would even triple. All sacrifices for the nice tint.
Numbers on highest setting
Throw 24 kcd
Output 680 lumen
Current 3.5 A
CRI hotspot 92.6
CCT 3454K duv –0.0008
