Clammed a lot on daytime digs: never dug after dark. Looks like I'm going to get a chance to try some night time clamming. What lighting set up works adequately for digging in the dark? I've got a propane Coleman, but have a hard time keeping mantles functioning for more than a short time. Are the LED shop lights, rechargeable or battery operated, pretty commonly used? What are most clammers using for lighting on night digs these days? Thanks for any info.
