OttLite Adjust LED Desk Lamp (Matte Black and Silver) review

Exact model and manual controls

This review covers the Matte Black and Silver OttLite Adjust LED Desk Lamp, exact current U.S. SKU CS01KC9-SHPR. The manufacturer product record lists that finish and variant, and the linked instructions name both the CS01KC9 family code and the -SHPR suffix. The product page describes a metal desk lamp with a flexible neck, dome shade and base. It is a corded tabletop setup; no clamp, clip or battery plan appears in the reviewed exact sources.

Adjust provides three touch-selected brightness levels and three manually selected color-temperature settings: 5,000 K, 4,000 K and 2,700 K. The manual says a longer press changes the color mode, while the product page says the lamp remembers the last selected color temperature. These are separate functions: the brightness steps do not mean the lamp senses the task, and the three Kelvin choices are not the same as the published color-rendering index. The exact sources do not describe automatic paper or screen modes.

Published color and size numbers have different jobs

OttLite lists CRI 95 and a maximum light output of 420 lumens. CRI is a manufacturer-published color-rendering specification; it is not an independent test. The lumen total is a measure of total emitted light, not a coverage width at a stated threshold. The manufacturer does not give a 90 cm width at 500 lux or center illuminance for this exact model. Buyers who need that numeric area should keep the finder requirement rather than infer it from the flexible neck, a high CRI value or the maximum lumen figure.

The page lists a height range of 3 to 22 inches and a 6-inch base diameter. A flexible neck can aim the dome, but the product page and manual do not count two linked supporting-arm sections. The listed height does not tell you where the shade can reach horizontally or what furniture it can clear. Compare the profile with a monitor, shelving and the work zone before relying on it in a tight arrangement.

USB and supplied adapter

The lamp has a separate 5 V / 2.1 A USB output near the lower rear. The instructions describe that port for devices such as phones and tablets; they do not identify it as a power input for the lamp. Lamp operation uses the supplied 24 V DC / 1 A adapter, with a listed 100–240 V AC input. Use the adapter specified for the exact model rather than treating the USB jack or a visually similar adapter as interchangeable. The lamp has no documented battery plan.

The LED source is integrated. The manual says the panel may become hot after extended use, instructs the owner to let the lamp head and adapter cool before handling, and says the light source is not replaceable by the consumer. The maker rates the LEDs for up to 40,000 hours; that is a stated rated life, not a service guarantee or an independently observed lifetime. The lamp is intended for indoor use.

How it compares with nearby choices

Adjust combines a flexible neck, manual warmth choices, dimming, CRI 95 and USB output in one base lamp. The White Beam has a simpler on/off control and no published numeric CRI or lumen value. The Prevention Pharmacy also publishes CRI 95, but its exact product supports two linked sections rather than a flexible gooseneck. Each comparison is about the manufacturer's documented structure and controls; it is not a claim of superior brightness, comfort or durability.

Consider Adjust if the Kelvin settings and touch dimming are more important than a two-section arm or replaceable bulb. If a broad work area or automatic sensor mode is essential, its exact page and instructions do not prove those capabilities. Confirm the -SHPR suffix, supplied adapter, footprint and cable route in the actual offer, then use the finder to compare the same conditions across the reviewed library.
