What to know about Northern Light Technologies Boxelite (NLT-BOX)

A large, Canadian-made clinical light box with a roughly 12 x 15 in front panel, rated for 10,000 lux at up to about 14 in. It uses warm-tone, UV-filtered compact fluorescent tubes. Wirecutter's pick for warmer light and Healthline's UV-free pick, for users who want to sit farther back.
Editorial notes

Why it stands out

Why we like it

The Boxelite is Wirecutter's pick for warmer light. Its 3500K output is softer than the cooler white of most LED lamps, and the large panel lets you sit about 14 inches back for a full dose.

The tubes are user-replaceable, so the lamp can be kept going rather than thrown out. Healthline also recommends it as a UV-free option.

What to know

Skip it if you want light or portable gear, or if you want to avoid mercury-containing bulbs. It weighs 11 lb, and the tubes contain mercury that the EPA says needs special cleanup and recycling.
