Thanks for all the responses, Figured they would be good to go but can never tell. Mine has the old school 3 led small pill and a 1 watt led bulb as main, I always thought they was more then enough. But both of our mains are carbide, Gear room has about 20lbs of calcium carbide with two generators and two lamps still in like new shape so plan on using em. Now just need to hook up with a grotto and see if its as fun as I think it yusta be. Last time we went was 07 convention in Marengo,Indiana. Good times and rained like cats and dogs.
