The bottom of the lamp has two slider buttons. One toggle adjusts the heat, from chilly white mild all the way in which to purple. One adjusts the depth, from ultra-bright right down to a glareless glow. Arduous faucets on every button skip forward, whereas holding the toggle down on one aspect or one other adjusts the sunshine settings fairly slowly—slowly sufficient I at first typically query whether or not it is occurring.
The utmost brightness is 1,000 lumens—the approximate depth of a 75-watt incandescent bulb. At this brightness, the battery lasts about 5 hours. At a decrease depth, this could lengthen to so long as a dozen hours.

There’s an added function I’ve come to understand at night time, which is the red-light mode. There’s little evidence that blue light from your little smartphone is keeping you awake at night time. However quite a few research do show that blue light wavelengths can affect melatonin levels and thus your physique’s circadian rhythm, whereas purple mild would not do that.
Red light therapy is, after all, the province of TikTok as a lot as science—a area the place wild exaggerations dwell alongside respectable makes use of and advantages. For each sleep examine exhibiting that purple mild is superior to blue mild in terms of melatonin ranges, there’s one other exhibiting that red light is associated with “negative emotions” before bed.
So I can solely provide my very own expertise, which is that Edge Gentle Go’s purple studying mild provides me a nice liminal house between awake time and sleepy time, one not supplied by a fundamental nightstand lamp. It permits me to form of take pleasure in a darkroom house that also lets me see and skim, and drift off just a little simpler.
If I go to sleep, the sunshine has an computerized 25-minute shut-off, which implies I will not do what I far too typically do, which is drift off whereas studying after which get up, alarmed, to a room crammed with vibrant mild in the midst of the night time.

This stated, for all of the virtues of portability, the Edge Gentle Go doesn’t boast a base that is heavy sufficient to cease the lamp from tipping over if I bend it ahead from its lowest hinge. This may be an annoyance when making an attempt to make use of the lamp as a studying mild from a bedside desk or the arm of a sofa.
