Historically one of my favorite light platforms was the D Cell Maglite. Lots of capacity, easy to use and due to the size hard to misplace. My main concern is leaking alkaline d cells. Now itís true that this can be completely avoided by storing empty but thatís also not very convenient. Only option I can think of is d to aa adaptors with L91s but thatís not very cost effective. Any other thoughts? Good quality adapters to use?

Any thoughts on the least leak probe D cells?
