I had a hard time finding a red light. I use it when riding in the fire engine at night to look at the maps without distracting the driver, or me. The light has a strong clip, the flexible shaft stays in position and the light is plenty bright.
The highest setting of the red light isn’t bright enough for me to read at night. The light also is difficult to attach to any book, so I have to sit it on the headboard of the bed which puts it further away. I’ve only used it a few times due to it’s inconvenience of use. It’s heavier than expected.
I got two of these, the first one was for me to have a bedside light in case I need to get up, and that doesn’t require electric, since I turn my electricity off at night. It’s perfect, so I got another one for my 6 yr old.
I love the reading light! At first I thought that it would be hard to read with the red light but you can easily read on the lowest light setting.
I love the light but am shocked at how fast the battery drains. I have to charge it every other day. Read the usage times carefully (I find I need it on the brightest setting to be able to read a book…so only 3 hours!) Please make one with a longer battery life!
