Your needs, this model
Does it fit your priorities?
What desk dimensions are listed for the Extended Reach?
OttLite lists a 9.75–27-inch height range, a 10.5-inch shade and a 6.5-inch-diameter base for this exact model family. These are planning measurements, not a horizontal reach map or a 90 cm width-at-500-lux claim; check where the flexible neck can place the shade on your desk.
Explore this need in the finder →Is its published color-rendering figure at least Ra 95?
Yes: the exact product page says its ClearSun LEDs have CRI 95+. That is a manufacturer statement, stored at the numeric threshold of 95 for this catalogue; it is not an independent measurement, and the sources do not publish a 500-lux coverage width or maximum lumen figure.
Explore this need in the finder →Does the flexible neck meet a two-linked-section requirement or support a clamp?
The manual says to steady the base and adjust the flex neck or shade, while the product record lists a tabletop lamp. The reviewed exact sources do not document two linked supporting-arm sections, a clamp or a clip, so do not infer those capabilities from the phrase Extended Reach.
Explore this need in the finder →The Extended Reach LED Desk Lamp is sold in Black as CSN85G5C-SHPR and White as CSN8500C-SHPR. OttLite’s current U.S. product page and product record list both finishes, and the matching instruction sheet names both retail codes. The sources describe the same stated functions for these versions, so this assessment treats them as finish variants of one lamp—not two separate lighting designs. This is a source-based review, not a hands-on test.
What “extended reach” tells you—and what it does not
OttLite lists the lamp at 9.75 to 27 inches high, with a 10.5-inch shade and a 6.5-inch-diameter base. Those figures help plan vertical clearance and tabletop footprint. The product page describes a flexible neck that holds position, while the instructions say to steady the base and grasp the flex neck or shade to reposition it. The exact sources do not give a horizontal reach diagram or a minimum distance from the base to the illuminated point. “Extended Reach” is the model name, not a measured reach guarantee.
The flex neck is also different from two linked supporting-arm sections. It lets the user aim the shade, but the exact manual does not count two separate structural links. Nor do the reviewed U.S. sources document a clamp or clip arrangement. If a lamp must clear a monitor, reach from behind a shelf or attach at the desk edge, measure the actual setup and confirm the product’s supported mount before treating the name or flexible shape as evidence.
Three touch-selected brightness steps
The maker lists three brightness levels controlled by touch on the shade. The instruction sheet describes one touch for the first setting, two for the next, three for the third, and a fourth for off. This gives a simple way to step between fixed output settings, but the pages do not provide a maximum lumen figure or a measured illuminance at a specified working distance. They also do not document a selectable Kelvin menu. If a precise output range or tunable color temperature is essential, the current record leaves those points unanswered.
OttLite says the ClearSun LEDs have a color rendering index of 95+. That is the manufacturer’s published CRI claim and meets a maker-published Ra 95 threshold in this guide’s comparison; it is not an independent measurement. The same product page does not list a width at 500 lux, so the CRI statement should not be used as evidence of a broad lit area. A color-rendering number, maximum lumens and coverage at a stated illuminance describe different things.
Power, assembly and service
The product instructions say the unit is fully assembled and use the supplied adapter. Its input is listed as 100–240 V AC, 50/60 Hz, with 13 V DC / 0.4 A output; the manual cautions against using a different adapter. This is a corded indoor lamp, not a rechargeable fixture. The manual also says the lamp head is not consumer-replaceable and that the integrated light source is not replaceable; when it reaches end of life, the instruction sheet says the whole luminaire must be replaced. That maintenance limitation matters if repairability is a priority.
The manual’s touch sequence is unusual enough to check before relying on it: the lamp cycles through brightness steps by repeated touches rather than using a separate brightness dial. Follow the printed instructions and avoid forcing the neck or shade beyond its adjustment range. The sources do not state a dimming memory function, a timer, a sensor mode or device-charging output for these two finishes.
Who should compare it
This model is worth considering when a tall listed maximum height, a compact circular base and straightforward touch brightness choices fit the desk. The documented CRI 95+ figure may also be relevant for people comparing manufacturer-published color-rendering specifications. The strongest reasons to look elsewhere are a need for a confirmed two-link arm, a clamp, numeric lumens, published 500-lux coverage, selectable color temperature, replaceable LEDs or a complete reach drawing.
Before buying, match the exact finish and SKU—Black CSN85G5C-SHPR or White CSN8500C-SHPR—and check that the package includes its own OttLite adapter. Confirm the 6.5-inch base fits without crowding other desk items, then compare the 27-inch stated maximum height with the shelf or monitor above it. These are practical package and space checks, not claims that this site has measured the lamp. For the full source-listed candidate set, use the desk-fit and color-rendering finder rather than assuming that every lamp with a flexible neck has the same mount or reach.
