I found another LED light product I like. This is a 25 cm long (approx 10 inches) strip of LED's in an aluminum channel with an opaque plastic front / diffuser. Power is supplied by a USB micro port on one end. Touch the end opposite to turn on or off. Plus touch and hold the other end and it dims. With 4.91 volts going in on highest setting it uses 0.83 ampere. Brightness? I can't measure lumens, but mounted under a cabinet, above a work counter it covers a 2 foot length reasonably well. Affix to surface with double stick tape (not included).
I bought mine on aliexpress. Chinese. $4.88 with free shipping; 30 days from order date to it dropping into my mailbox. I've seen them on ebay for $9 buy it now and also on auction but have not followed to see ending prices.
