Light therapy lamps are marketed mostly for seasonal mood support, but for shift workers they serve a different, well-supported purpose: helping shift your circadian rhythm so your body treats "night" like day when you need to be alert, and vice versa. Most lamps on the market aren't optimized for this use case, so here's what actually matters when choosing one.

What to look for

Brightness: 10,000 lux, not less

This is the single most important spec. Circadian-shifting effects are well-documented at 10,000 lux for 20-30 minutes; dimmer "ambiance" lamps marketed as light therapy but rated well below this (some are only 2,500-5,000 lux) require much longer exposure to have a comparable effect, if they work at all for this purpose.

Size and distance

Lux rating is measured at a specific distance — check the manufacturer's spec (usually listed at ~12-18 inches). A physically larger panel lets you sit slightly further away or off-center while still hitting the target lux, which matters if you're using it while working, eating, or getting ready rather than sitting perfectly still in front of it.

UV filtering

Look for lamps explicitly stated as UV-filtered. The beneficial effect comes from visible light exposure to the eyes, not UV — a filtered lamp gives you the benefit without the skin/eye risk of unfiltered UV exposure over repeated daily use.

Timer and brightness adjustment

Useful for building a consistent routine (start low, ramp up) and for fitting sessions into a shift break rather than requiring a dedicated block of time at home.

How to use one for shift work

Fixed night shift: use it in the first few hours of your shift to reinforce "daytime" alertness signals, then avoid bright light later in the shift so it doesn't interfere with winding down before sleep.
Transitioning to nights: use it in the evening on the days leading up to a night-shift stretch to gradually shift your rhythm later, paired with the melatonin timing approach in our melatonin guide.
Early morning shifts: use it immediately upon waking to help lock in an earlier rhythm — this is often the single most impactful use case for light therapy in shift work.

What's not worth paying extra for

Wearable light-therapy devices (glasses, visors) are convenient for mobility but typically deliver light closer to the eyes at lower total lux than a desktop panel — check specs carefully rather than assuming "wearable" means "more effective." For most shift workers, a well-specced desktop panel used consistently outperforms a premium wearable used inconsistently.

Pair light therapy with the blackout strategy in our day-sleeper bedroom guide — light exposure and light avoidance are two sides of the same circadian lever, and using only one limits how much they can help.
