The Edge Light Go features two slider buttons that adjust warmth and intensity, with a maximum brightness of 1,000 lumens. The lamp has a red-light mode that can be used for reading at night, which some studies suggest can help regulate melatonin levels.
Users have reported finding the red light to be a pleasant way to transition from awake time to sleepy time, allowing them to read and relax before bed. The lamp also features an automatic shut-off after 25 minutes of inactivity.
However, the Edge Light Go has some limitations. Its base is not heavy enough to prevent the lamp from tipping over if bent forward, which can be a problem when using it as a reading light on a bedside table or couch arm.
