What are the best light therapy lamps to buy in the UK?
Our top pick for Light Therapy Lamps in the UK is the Lumie Vitamin L Slim SAD Light Therapy Box.
The Lumie Vitamin L suits buyers who want a slim light box with its brightness stated at a distance (10,000 lux at 20 cm), a 20 x 28 cm surface area, Medical device (class 2a) status and a 3-year warranty, all on the listing.
The Lumie Vitamin L is our top pick light therapy lamp because its listing states 10,000 lux at 20 cm, a 20 x 28 cm surface area, UV-free light, Medical device (class 2a) status and a 3-year warranty. For a SAD lamp with adjustable colour, the Beurer TL35UK lists 6,500 K, 4,300 K and 3,000 K settings and a 4-stage dimmer, and its title calls it a medical device; for timers, the Sotipevs lists six settings from 10 to 60 minutes and up to 15,000 lux.
This guide compares six lamps from Lumie, Beurer, Sotipevs, Trayvespace and Easysleep on what each listing states: brightness and the distance it is given at, colour temperature, dimming, timers, medical device status and warranty. Stated brightness runs from 10,000 lux to up to 15,000 lux on the Sotipevs, and two listings give a distance for their figure: the Lumie Vitamin L (20 cm) and the Beurer TL30UK (10 cm).

Our process
How do we choose our picks?
We don’t lab-test products ourselves. Instead we synthesise current Amazon UK listings and published specs into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We check each pick against live Amazon UK catalogue data rather than last year’s model lists. Stock moves fast, so a listing can sell out after we publish.
Published specs
We compare manufacturer specifications so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage and plug/fitting standards — details that generic global lists miss.

Editor's Note
Two of these six listings say at what distance their lux figure applies: the Lumie Vitamin L (20 cm) and the Beurer TL30UK (10 cm); the other four give a lux figure with no distance. Three describe the lamp as a medical device (the Lumie Vitamin L as class 2a, and the Beurer TL35UK and TL30UK in their titles), and the Lumie Vitamin L is the one listing that states a warranty term.
Our Take
As a default, pick the Lumie Vitamin L: 10,000 lux at 20 cm, a 20 x 28 cm surface area, Medical device (class 2a) and a 3-year warranty, all on the listing. For adjustable colour, the Beurer TL35UK lists 6,500 K, 4,300 K and 3,000 K with a 4-stage dimmer; for timers, the Sotipevs lists six settings from 10 to 60 minutes.
