Thanks for all the suggestions -

Clarification - I am considering lights with Up- To 4 cells. So can have 1 cell, 2, 3 or Four of the 18650’s

And up to 5,000 Lumens on Turbo if possible :slight_smile:

But seems like the Emisar D4 is on the upper end of practical use on Turbo? What is one step down from the Emisar D4?
