OttLite Balance LED Desk Lamp (Black with Antique Brass Accents) review

The OttLite Balance LED Desk Lamp (CS01KA9-SHPR) brings a traditional-looking counterbalance arm into the brand’s ClearSun desk-lamp line. It is a Black metal lamp with antique-brass accents, a six-inch base, a 10-inch arm dimension from pole to shade, and a listed height range of four to 18 inches. Its light is manually controlled, while a separate USB port provides wired device charging. This source-led assessment checks the exact current product page and variant record against instructions that name the Balance model and its assembly steps, then uses the corresponding official image to confirm visible configuration. No ownership or physical test is claimed.

Counterbalance adjustment is a mechanical setup

The manual asks the user to attach the counterbalance piece to the arm before connecting power. It then describes loosening a thumbscrew to adjust arm height, tightening it again, and using a separate joint and shade rotation for final aiming. This is not a tool-free motion claim: the thumbscrew must be managed, and OttLite warns against overtightening because that can strip the thread. For someone who wants to reposition the light repeatedly, the adjustment sequence is worth considering alongside the style of movement. The stated four-to-18-inch height range is not a complete horizontal reach map.

The instructions identify one counterbalance arm above a fixed support; the shade has its own joint. Balance therefore does not meet the finder’s requirement for at least two linked supporting-arm sections, even though it has more than one adjustable point. Its six-inch base diameter is a concrete tabletop-space check, and the pictured black-and-brass finish has more visual detail than a plain utility lamp. Neither the image nor maximum-height specification proves that the arm will clear every monitor, shelf, or desk edge.

Published Ra and manual light settings

OttLite lists CRI 95, three brightness settings, and three color-temperature modes: 2,700 K, 4,000 K, and 5,000 K. The product page also gives a maximum output of 428 lumens and an LED life rating up to 40,000 hours. The manual says the lamp remembers the last color mode setting. These are useful maker-published specifications for comparison, not measurements made by this site. The CRI value meets a source-based Ra 95 filter, while the exact model’s sources do not provide a 90 cm width at 500 lux or a center illuminance at a stated distance.

Brightness and color temperature are controlled with the touch switch on the base. One short press selects among three brightness settings, and holding the switch changes color mode. That can be simpler than a separate knob but makes it important to understand the sequence before deciding whether it fits your preference. OttLite says its ClearSun technology is designed to reduce eyestrain; the statement is attributed to the maker and is not an independent clinical or comfort finding. A high published Ra does not itself establish a particular broad-beam result or eliminate glare from the user’s monitor.

USB and adapter have different jobs

The lamp uses a supplied 24 V DC, 1 A power adapter and is intended for a household AC outlet. A separate USB port on the rear of the base supplies 5 V at 2.1 A to devices. The lamp’s adapter is not interchangeable with the USB output, and USB charging does not make the light cordless. Check the outlet location, adapter routing, and where a phone cable will sit near the six-inch base. The product sources do not state wireless charging or a backup-battery lighting mode.

Balance has integrated LEDs; its instructions state that the light source is not replaceable and that the whole luminaire must be replaced when the source reaches end of life. They also warn that the LED panel can become hot after extended use and say indoor use only. This service constraint is more concrete for ownership planning than a rated-life claim alone. Review the exact seller’s warranty and returns policy and confirm that the included adapter and counterbalance part are in the package before purchase.

What to compare it against

Balance belongs in a shortlist where a traditional counterbalance arm, manual Kelvin choices, published Ra 95, and wired USB charging are all useful. It differs from OttLite Direct, which uses a brass finish and its own one-arm geometry, and from the dual-shade lamp, which splits the head and adds local audio instead of a counterweight adjustment. Do not treat their similar 5 V / 2.1 A USB port or shared brand as proof that the power adapter, finish, dimensions, or controls are interchangeable.

Consider another model if a clamp, a smaller footprint, automatic paper-and-screen sensing, a quantified wide beam, or two linked arms are hard requirements. The Balance page does not report a 90 cm width at 500 lux, and the manual does not show a second supporting link. Its 428-lumen maximum is not a substitute for that measurement. The most important exact checks are the black/antique-brass CS01KA9-SHPR code, the supplied 24 V adapter, the attachment of the counterbalance, and the clearances around a 10-inch arm and independently movable shade. The official image confirms the design language, not the lamp’s reach, output, stability, or color performance in a real workspace.
