The wasser90 is an integrated-LED desk light that clamps onto the edge of a desk. According to the sales page specs, brightness is up to about 400lm, the light color has 3 steps—warm white at about 3000K, neutral white at about 4000K, and daylight at about 6500K—and dimming is 4-step with a press or stepless with a long press. Three hinges and a tilt structure let you adjust the light's angle, maximum power consumption is about 10W, and the weight is about 515g (including the clamp). Rather than a type that emphasizes high output, it is an LED clamp light chosen for its range of color and brightness adjustment, the space-saving clamp design, and its flexibility, worth considering for study desks, reading, and remote-work desks. Check the sales page for the latest pricing, stock, and color options.

Design
A clamp-on LED desk light with a slim, simple design. The size is listed as about H670 × W500 × D57mm, the weight as about 515g including the clamp, and the materials as ABS and aluminum. The sales page notes that the surface has a hairline finish. It comes in gunmetal black and silver white, and gunmetal black also fits easily into a black-based desk setup. The sales page lists the width of the light-emitting area as about 25.5×3.4cm.
3-step color adjustment at 3000K / 4000K / 6500K
It is a color-adjustable desk light whose light color can be chosen from 3 patterns: warm white at about 3000K, neutral white at about 4000K, and daylight at about 6500K. One unit can switch between use as a warm-toned 3000K desk light and as a white-light 6500K desk light. The sales page states that color is adjusted with buttons on the side of the body. How colors look varies with room lighting and surroundings, so treat each color temperature as the value listed on the sales page.
4-step plus stepless dimming and up to about 400lm
It is a dimmable desk light whose brightness, according to the sales page, can be adjusted in 4 steps by pressing the button or steplessly by holding it. Brightness is up to about 400lm. The sales page lists illuminance of about 1,560lux at 40cm directly below (measured with neutral white at maximum brightness) and describes the brightness as equivalent to JIS standard class AA. However, the brightness you need depends on your task, the installation position, and the room environment. Rather than the size of the numbers, the model's feature is that fine dimming lets you match the brightness.
Clamp-on design and 3-hinge flexibility
Because it clamps to the desktop, no freestanding base sits on the desk, making it a clamp-on desk light that helps keep work space free. Three hinges and a tilt structure let you adjust the angle, and the sales page says it can light anything from a spot at your hands to a wide area of the desk. The supported desktop thickness could not be confirmed on the sales page, so check the desktop requirements on the sales page or with the seller before buying.
Maximum power consumption of about 10W and power
Maximum power consumption is listed as about 10W. It is used by plugging the cord attached to the body into a household outlet, and there is no built-in battery. Checking the outlet position and its distance to your desk in advance makes planning the installation easier.
How it differs from the wasser39
The wasser39 from the same wasser series is a clamp-on model with up to about 760lm, 5000K, stepless dimming, a half-light mode, and a slim arm. The wasser90, by contrast, has up to about 400lm, 3-step color adjustment at 3000K / 4000K / 6500K, 4-step plus stepless dimming, and 3 hinges. The point is to choose by use: a fixed light color adjusted by brightness and half-light, or switching the color tone with color adjustment.
How it differs from other desk lights
R13 Picks also features desk lights of other types. The wasser27 is a freestanding model with stepless dimming and color adjustment, a 30-minute timer, and a night light, and the LED DECO LIGHT 001 is a freestanding model focused on 3-step dimming and touch controls. The atRise Y0662 is a base-type light that can be used cordless if you choose a rechargeable type, the Sanwa Direct 800-LED079 is a clamp-on light with 3 lights and up to about 1650 lumens, and the LIT000101 is a freestanding desk lamp that uses an E26 bulb. The point is not which is better, but choosing by installation method, light color switching, and the area you want to light.
Use for study desks, reading, and remote work
The sales page lists use at study desks, for reading, and in offices thanks to the color adjustment function. You can consider it if you are looking for a light to keep installed on your desk—for studying as a study desk light, for lighting your hands as a reading light, or for lighting around your PC as a desk light for remote work and telework. To set up your whole desk area, R13 Picks' "5 desk setup picks" and "10 Best Work Gadgets" may also help.
Points to check before buying
The sales page describes the LED light source as "easy on the eyes," but how light looks and feels varies from person to person. The desktop thickness the clamp supports could not be confirmed on the sales page, so check your desk's conditions in advance. The warranty is listed as 1 year (limited to natural failures and initial defects under normal use according to the manual), but the latest terms on the sales page take priority. Check the sales page for the latest pricing, stock, and color options.
