While we play, it seems satisfying to switch on a light and see a carefully crafted, round beam etched onto a wall. Some lights which are above average in $$$ fail to accomplish this. Found one that does ... Ravovac industrial ... about $5.00. Amazingly (at least to me) designed reflector. Small facets which seem integrated into a series of concentric circles stepped up from the lamp position. Almost perfect circle of concentrated beam at center with an outer corona so well defined that the molded ridges of the lens cap are projected onto the wall.
