Following the instructions from ScubaBoard and South West Mafia prove quite successful.

  1. Order CREE 2 drop in module.
    1. Cree R2 Drop-In 1-Mode LED Module (3.7V~18V / 26.5mm x 29mm). Item# 11836
  2. Wait… shipping’s from HK.
  3. Make a spacer
    1. Match the thickness of the body of the SL4 – OD 33mm, ID 26mm, Depth 6mm
    2. Or do not make a spacer and twist the copper wire appropriately.
  4. Install batteries backwards, reversing polarity.
  5. Enjoy
