What's the difference between the Fenix SD11 and SD20 dive lights?Updated a year ago
There are a couple differences between the two lights. The first being is that the SD20 is longer than the SD11. So much so that the SD20 requires two 18650 batteries to operate and the SD11 only requires one. Another difference is that when the SD11 came out, it was an upgrade so with that being the case, you see the same turbo mode, 1000 lumens, on both lights but their high modes are different. The SD11 has 100 extra lumens on high than the SD20. Then another big difference is the red light that they both offer. The SD20 has 105 lumens with the red LED where the SD11 has 250 lumens.
