Redgrass R9
no budget ceiling
The highest verified colour rendering in a 14-source field — extended CRI 98.5 from 96 custom LEDs, on two rotating bars that cancel surface shadows.

■ The catch — co-equal billing, always
It is locked at 5000K and you cannot buy it on Amazon. There is no warm setting for evening reading, and Redgrass Creative is a direct-to-consumer miniature-painting brand that prices in euros — EUR 279.99, roughly $305 for a US buyer before shipping and any duty, with no US retail channel behind it.

Traps — this verdict avoids
Why the Redgrass R9 is right for you
It avoids every trap below — and for just me, no budget cap, it is the pick because it delivers:
Lumens are the wrong number
Lumens describe total output, not what lands on your desk. Only lux at a stated working distance is comparable, and exactly one lamp here publishes it — 3,700 lux at 45 cm. A focused 750-lumen beam can put more light on the page than a wide 1,000-lumen one.
Flicker-free is a marketing word
Most cheap lamps dim by pulse-width modulation — switching the LEDs on and off hundreds of times a second — and that is the actual eye-strain mechanism. Only PWM-free constant-current dimming avoids it. A lamp that says flicker-free without saying PWM-free, or quoting a flicker percentage, has told you nothing.
2025's top picks are unbuyable
Three lamps that anchored last year's guides are gone in 2026: the BenQ e-Reading (discontinued, every US colour variant unavailable), the TaoTronics TT-DL16 (brand wound down, no live US listing) and the Brightech Litespan 2-in-1. Any 2025-dated guide is recommending a lamp you cannot buy.
