We only recommend products we think are worth it. Some links on this page are affiliate links: if you buy through one we earn a commission from Amazon, at no extra cost to you, and as an Amazon Associate we earn from qualifying purchases. It never changes which products we pick or how we rank them. This is not medical advice. If you are unsure what you need, ask your GP or occupational therapist.
Short answer. A daylight lamp is a very bright, ultraviolet free lamp. The NHS says light therapy “is not usually available on the NHS as there’s not enough evidence to tell whether it’s effective”, while also noting that many people find it helps their symptoms. Nobody advertising one in the UK is allowed to offer it as a treatment for seasonal affective disorder unless a suitably qualified health professional is supervising, so this page tells you what the specification means and leaves the claims alone. Typical price: 25 to 180 pounds.

What can and cannot be claimed
The Advertising Standards Authority guidance on seasonal affective disorder is specific. Presenting light therapy as a treatment for SAD without the supervision of a suitably qualified health professional risks discouraging essential treatment, which breaches rule 12.2 of the CAP Code, and the ASA has ruled against advertisers on that basis, including sunbed operators in November 2019 and again in January 2026. Where supervision is in place, efficacy claims still need strong clinical evidence behind them.
This page carries affiliate links, which makes it advertising, so the rule applies to us as much as to anyone selling a lamp. We are not claiming that any lamp on this page treats seasonal affective disorder, improves mood, or does anything beyond producing bright light. If you think you have SAD, that is a conversation to have with your GP.
For the same reason we have left out lamps whose Amazon listings claim to treat depression or seasonal affective disorder outright, even where the hardware looks identical to the ones below.
What the NHS actually says
- Light therapy is not usually available on the NHS because there is not enough evidence to tell whether it is effective.
- If you buy one, NHS guidance points to a light box of about 10,000 lux that is ultraviolet free and carries a UKCA or CE mark, used according to the manufacturer instructions.
- It may not be suitable if you have certain eye conditions or take medicines that increase sensitivity to light.
- The treatments the NHS does list for SAD are antidepressants, talking therapies including CBT, and light therapy, and many people need treatment each winter.
Lux is a distance measurement, which is the catch
Every lamp in this category is advertised by its lux figure, and lux is measured at a stated distance from the lamp. Light falls away sharply as you move back, so a lamp that genuinely produces 10,000 lux at 20cm may be producing a fraction of that at the arm length where you would actually sit.
What to look for, in order.
- The distance the lux figure is quoted at. If the listing does not say, the manual usually does. If neither says, the figure means nothing.
- Screen size. A larger panel is more forgiving of how you sit, because you do not have to keep your face in one spot.
- Ultraviolet free, with a UKCA or CE mark. Non negotiable.
- A stand or mount that works on your table. The commonest reason these end up in a cupboard is that there is nowhere sensible to put them.
- Dimmable, with a timer. Useful if you are following instructions about session length.
Who should ask first
Speak to a doctor or pharmacist before using one if you have an eye condition, if you take medicines that increase light sensitivity, some antibiotics and some skin treatments among them, or if you have been diagnosed with bipolar disorder. This is general information rather than medical advice.

Frequently asked questions
Is a daylight lamp the same as a SAD lamp?
The products sold under both names are usually the same thing. The difference is what the seller is claiming, and the claims are what the rules restrict.
Will it help me see better for reading or hobbies?
A bright, evenly lit surface genuinely makes fine work easier, and for that purpose a daylight reading lamp or a magnifier lamp is the better buy and considerably cheaper.
Does a sunlamp or sunbed do the same job?
No, and this is where advertisers have been in trouble. Those produce ultraviolet. A daylight lamp is specifically ultraviolet free.
Can I get one on the NHS?
Not usually, for the reason given above. Some employers and some local wellbeing services lend them out, so it is worth asking before buying.
When would I use it?
Follow the manufacturer instructions, which normally means a set period in the morning. If you have been given advice by a clinician, that advice wins.
What if it makes me feel worse?
Stop, and tell your GP. Headache and eye strain are reported often enough to be worth mentioning.
