UK D4 and C6 Conversion

[Jonno]

Hi is there any conversions available to modify these lights to LED/Cree please.

Thankyou

The issue you have with these two hosts is that the existing heads are plastic, meaning there's a limit to how hot you can drive any LED replacement system. Plus the Lithium equivalents of C and D cells are both slightly longer. Having experimented with the UK C6, I can tell you that 6*25500 C Cell Lithium-ion's will not fit in the body. You have to go 4*C Cell Li-ion's plus spacers or stick with NiMH of 1.2V each. As for the D4 I do not know here whether 4*32600's will fit.
