I purchased a regular ott light to use next to my sewing machine when necessary on sale at Joanns several years ago. I use it sparingly since I have an autoimmune disease that can flare if I am exposed to sunlight or the ott light unprotected. I recently purchased a small handheld OTT light at Joanns with a coupon. I use it to tell what color my clothing is when I am getting dressed in the morning. Between getting older and beginning cataracts I have the worst time tellig black from blue in particular. I can't remember how many times I have ended up with blue pants and black socks or the opposite. One time I actually did a public presentation with the wrong color blouse.
