Glocusent 72 LED Clip-on Reading Light: Specs, Pros & Cons
Almost every clip-on reading light sold today runs on a battery, and the pitch is always portability. Glocusent's 72 LED model goes the other way. It has a plug, a cord long enough to reach a wall socket from a headboard, and no battery at all. That single decision defines the product: it never needs charging and it never fades at the end of a long session, but it also never leaves the bed it is clipped to.
The head is a wide disc, with a shade around the rim to stop light spilling sideways into your eyes, and the diodes are spread across its face. The intent is to cover an open book evenly instead of throwing a hot spot at the middle of the page. Three colour settings run from a warm amber for late reading up to a daylight-neutral white for work at a desk.
Mounting is the other thing it takes seriously. The gooseneck is metal wrapped in silicone, stiff enough to hold an angle through an evening once set, and the clip is wide and padded rather than the small spring jaw you find on a book light. This is built for a headboard, a bunk frame or a desk edge. It clips to furniture, not to a paperback.
The compromises all follow from the cord. A socket has to be within reach, which quietly decides which side of the bed the light can live on, and the assembly is bulkier and more visible than a slim rechargeable clip. There is a version with a remote control, but it is a separate variant chosen at the moment of purchase, and it cannot be added later.

How this VS Score was computed
Score 48: each known spec is measured against the median of book lights (9 products, medians winsorised to the 10th–90th percentile), then weighted. 40% of the scoreable weight could be used; unknown values, features not applicable to this class and proxies (battery capacity where a rated life exists) add or remove nothing.

Editor’s note
What sells this over an ordinary bedside lamp is not brightness, it is containment. The shade around the head and the amber setting exist so that one person can read while another sleeps a foot away, and that is an awkward problem most lights ignore entirely. If you share a bed, or you are on the top bunk, that is the specific reason to look at this one.
It is bright for the category. Two hundred and twenty lumens is well past what a printed page needs, and that matters, because the useful range then sits at the bottom of the scale. That is exactly where five fixed steps start to feel limiting – a stepless dial would let you land between the first and second setting, which on a light this strong is where you want to be. The auto-off timer, by contrast, earns its place immediately: falling asleep mid-chapter is the normal failure mode for reading in bed, and this deals with it.
One honest warning about the specification. The listing carries an illumination-time figure of eighty hours, which means nothing on a mains-powered light and looks inherited from a battery product. It is not in our table for that reason. Glocusent publishes no weight for the unit itself either, so the figure quoted in shop listings is packaging.
Who regrets it: anyone who reads in a chair nowhere near a socket, anyone who travels with their light, and anyone who wants something discreet. For them the same brand's rechargeable 26 LED clip light is a better shape of the same idea.

The bottom line
The Glocusent 72 LED Clip-on Reading Light earns a VS Score of 48, a solid mid-pack result among the 9 book lights we compare here.
- Who it’s for
- Someone who reads in bed beside a sleeping partner, or on a bunk, and would rather the light stayed put and stayed lit than travelled with them.
- Who should look elsewhere
- Readers who carry a book around the house, or whose reading chair is nowhere near a socket. This needs mains power and a fixed clipping point, and neither is negotiable.
- The trade-off that matters
- You give up ever taking it anywhere in exchange for never thinking about charging it, which is only a good deal if your reading happens in the same spot most nights.
- The main alternative
- Glocusent 26 LED Clip on Reading Light – the same brand's rechargeable, stepless-dimming clip light, far smaller and portable, if you are not tied to one place.
