It’s good to know that you can use a pro-style level in a poorly lit room if the need arises. The Lightning Level’s three lighted vials make measurements easy to read in low light or complete darkness. Accurate to .0005 inch per foot, the level features an auto shutoff, a V-groove on one side for round stock, and rubber-polymer end caps. Four models are available measuring 24 and 48 inches. Cost: $45 to $75. Swanson Tools. 815-469-9453. www.swansontoolco.com.
