Dyson Solarcycle CD05 Desk Lamp review

Two finishes, one documented CD05 configuration

Dyson’s current U.S. desk-lamp collection shows the Solarcycle desk CD05, and its U.S. product selector identifies Black/Black and White/Silver. I treat these as finish variants of the same desk-lamp configuration, not as different light engines. The reviewed U.S. pages do not state separate retail SKUs for the colors, so a specific code should be confirmed from the offer rather than inferred from CD05. Both exact finishes have their own manufacturer image below.

Light figures have different meanings

Dyson lists 1,120 lumens of light output, a 1,194-lux average level, a 2700–6500 K color-temperature range and CRI 90 minimum. These are manufacturer specifications, not measurements from this review. In particular, the average-lux figure is not a published beam-width result at 500 lux. The reviewed product page does not say that the lamp maintains at least 500 lux across 90 cm (about 35.4 inches), so it cannot be treated as meeting that finder threshold. Likewise, CRI 90 minimum falls short of the separate Ra 95 requirement; brightness, adjustable white tone and color fidelity are not interchangeable claims.

Three-axis Glide gives the head and arm assembly multiple ways to move, but it should not be read as a two-section arm. The exact product images show one main support member between the upright and optical head. That distinction matters if linked support sections are a must-have. A movement-axis count does not tell you the reach path around a display, nor does the maker’s height figure of 27.7 inches establish clearance at your desk.

Base, sensing and app routines

The desk version is documented with a round tabletop base. No compatible clamp or clip setup appears in the reviewed U.S. product page or CD05 instructions, so this is not a source-backed choice for a desk-edge mount. The 12.79-pound listed weight and base image describe the product, but they do not certify support on an uneven, narrow or delicate surface. Check the actual base dimensions, room for the cord and intended placement before relying on a fit.

The control story combines features that should be kept separate. The manual controls allow brightness and color adjustment. An ambient light sensor adjusts illumination in response to surrounding light, while the movement sensor controls automatic on/off behavior. The app’s local-daylight schedule uses location, date and time; Dyson’s description says the lamp does not measure the real outdoor light level in real time. That scheduling feature is not evidence of automatic paper and screen modes. No paired mode for switching between a page and a display is documented in the reviewed CD05 sources.

There is a small but practical source conflict: the exact product page gives a two-minute no-movement shutoff, while the CD05 user manual says five minutes. I preserve the conflict rather than choosing one interval. If an automatic cutoff time matters to your routine, check the current instructions for the exact unit and firmware instead of treating either statement here as settled.

Power and long-term checks

The lamp has integrated LEDs and a USB-C charging point. Its 3.2-meter power cord and 21-watt rated input are useful planning details, although the reviewed sources do not establish a USB-C output rating or every compatible device. The light source is not designed to be replaced by the user. Dyson’s 181,000-hour life figure is an L70 estimate based on eight hours of use per day; it is a manufacturer calculation, not a warranty promise or a lifespan observed by this site. Confirm current warranty and service terms with the exact offer.

CD05 is a reasonable comparison for someone who wants a weighted-base lamp with a broad manual color range, local-time scheduling, ambient sensing and a device-charging point. Its documented limits are equally important: no stated 90 cm-at-500-lux width, no Ra 95 claim, no two-linked-section arm and no documented paper/screen automation. For a different Dyson desk configuration, compare the Solarcycle Morph CD06 review: its specification sheet documents two linked support sections, 850 lumens and a distinct warmer CCT range while docked. This assessment is source-based; it does not claim hands-on use, lux testing, stock checking or seller-price comparison.
