I have a colman battery light as well. I have found that using the D cell batteries get eaten up pretty fast. but if you use the 6Volt batteries, they seem to hold up pretty decent. I have only changed them out 2 or 3 times for the whole season of fishing. I am looking to get another one to hang on both sides of my house to brighten it up in there. I do like the propane ones, they seem to shine brighter at night than the batteries. i also use a headlamp to walk off of the ice, but not this year, i will be using the lights of my sled to get off.
