I saw a Target sale this week for the Stanley MaxLife MiniTripod #95-111 and purchased two of them for the TD and camping. Even though we have overhead reading lights these work better when placed on the shelf behind us. They will shine directly on the page you are reading and won’t disturb the person next to you. Jane has had many book lights and got tired of replacing the halogen bulbs. These use 3 AAA batteries and switch from 1 to 2 or 3 LED’s. When the legs are folded they measure 2" x 6" and are small enough for the pocket. There is another mini that has a key ring but I haven’t seen one work.link
The tripod will come in handy when you need both hands free. For around $15 each I think they are a great value for anyone who camps.
