Your needs, this model
Does it fit your priorities?
Does Harmonize meet the finder’s Ra 95 threshold?
OttLite’s exact page publishes CRI 95. That qualifies for the documentary filter, but it is a maker specification rather than an independent color test.
Explore this need in the finder →Does its 440-lumen maximum prove 90 cm at 500 lux?
No. The page lists 440 lumens, but the exact Harmonize sources do not state a width at the 500-lux threshold.
Explore this need in the finder →What powers the lamp, and is its USB port an input?
The supplied AC adapter powers the corded lamp; the separate 5 V / 2.1 A port is a device-charging output, not USB lamp power.
Explore this need in the finder →The OttLite Harmonize LED Desk Lamp is listed in brushed steel as SKU CS01SV9-SHPR. Its U.S. product page describes a metal lamp with a counterbalance arm, adjustable shade, three brightness settings, three color temperatures and a 5 V USB output. The maker also publishes CRI 95 and a 440-lumen maximum. This assessment uses the exact product page, the variant record and instructions that name the Harmonize code; it is not a hands-on review or a measurement of color, output, stability or comfort.
Manual color changes, with one useful numeric color claim
The exact page lists three color-temperature modes but does not name them. The model-matched instructions supply the useful detail: 5,000 K, 4,000 K and 2,700 K. A short hold on the touch control changes color mode, while successive touches select three brightness levels and then turn the lamp off. The page's CRI 95 claim is separate from those warm-to-cool settings. It meets the finder’s documentary Ra-at-least-95 condition, but it remains a manufacturer specification, not an independent test or a promise about how a particular color will appear.
Nothing in the exact product page or manual describes ambient sensing or automatic paper and screen modes. Nor does the source set state a 90 cm (35.4 inch) width at 500 lux. The listed 440-lumen maximum describes total output, not the area that reaches a specified illuminance; neither the lumen figure nor a color-rendering value can be converted into that width. Harmonize therefore suits a buyer comparing a stated Ra value and manual Kelvin choices, not someone requiring that quantified broad-area claim.
Counterbalance geometry and a small circular base
Harmonize is a corded tabletop lamp, not a clamp or clip model. OttLite lists a 6-inch-diameter base, a 5-to-19-inch height adjustment and a 7.75-inch arm measured from the pole to the shade. The counterbalance styling gives this model a different job from OttLite’s simple flexible-neck organizer lamps: the arm and adjustable shade can be set to direct light from above a work area. However, the published height range and one arm length do not form a complete horizontal reach map. The maker’s instructions describe loosening a thumbscrew to adjust the arm and moving the shade joint; they caution against overtightening. Allow room for the base, shade and cable, and compare your own monitor and shelf positions with the actual diagram rather than assuming a reach from the lamp’s maximum height.
The exact sources identify a counterbalance arm and shade joint, but do not document two linked supporting-arm sections as the questionnaire defines them. The separate shade movement is not enough to count the fixture as a two-section arm. This distinction is useful when comparing it with the longer two-link designs that can move a lamp head across a wider desk footprint.
The USB port is separate from lamp power
The Harmonize instructions say to use the supplied AC adapter: 100–240 V AC input at 50/60 Hz and 24 V DC output at 1 A. They identify a separate 5 V, 2.1 A USB output near the bottom rear of the lamp. That port is for charging a connected device; it is not a USB power input for the LEDs, and the sources describe no rechargeable lighting mode. Check where the power brick will sit and how a device cable will cross the desk. The stated rating does not establish compatibility with every device or the time required to charge one.
The manual identifies the lamp head and integrated light source as non-user-replaceable and says the lamp is for indoor use. That matters if you would rather replace a bulb than the fixture. The product image shows the brushed-steel finish, counterbalance arm and tabletop base. It cannot establish light distribution, a particular arm feel, stability or USB performance.
Who should compare it
Harmonize is a plausible comparison for a desk where an adjustable metal shade, a compact circular base, manual 2,700/4,000/5,000 K choices, published CRI 95 and a wired device-charging port belong together. The Black Renew, for example, also publishes CRI 95 but adds a digital display and six brightness levels; it uses a different body and its sources do not establish Harmonize’s arm design. A wireless organizer such as OttLite’s separately named White Organizer 7QC00W trades the numeric CRI evidence and wired output for integrated storage and a wireless pad. These are different feature bundles, not interchangeable variants.
Before ordering, match the offer to brushed-steel CS01SV9-SHPR and confirm that the supplied adapter, arm components and USB port correspond to the exact package. Check the arm’s clearance against the desk layout, and verify the seller’s current return and service terms for an integrated LED. The source images and maker claims provide a research basis, not proof of measured performance. For the broad set of reviewed tabletop-base lamps, the finder keeps the base condition explicit; choose the separate published-Ra condition only if that numeric manufacturer claim is essential.
