Design and Build
The Lastar CM011A adopts a simple, modern rectangular design with a white finish, intended to blend into various home settings like desks, kitchen counters, or vanities. Its compact size is a standout feature, measuring only 5.3 by 4.7 by 2.0 inches, which makes it highly portable and easy to store. The build incorporates a metal base for stability, though the overall construction is lightweight for easy transport. The lamp is finished in white and described with a modern style, presenting a clean aesthetic. It is strictly for indoor use and is not water-resistant.
Performance and Features
Light Output and Therapy
The core performance metric is its 10,000 lux intensity, which is the recommended brightness level for effective light therapy to influence circadian rhythms and mood. The lamp uses 60 evenly distributed LEDs to deliver this full-spectrum, daylight-mimicking light at a power draw of only 12 watts. A key safety and comfort feature highlighted by the manufacturer is the absence of UV light or other polluting radiation. To achieve the full 10,000 lux intensity, the lamp must be positioned at the recommended close distance, a detail confirmed by user feedback noting its powerful output.
Customization and Controls
Customization is a major strength. Users can adjust between five brightness levels (5% to 100%) and four distinct color temperatures, ranging from a very warm 1600K to a cool, daylight-like 6500K. This allows the light to be tailored for different activities and times of day, such as a warm glow for relaxation or cool light for focus. Control is managed entirely through touch-sensitive buttons on the device. The lamp also offers several preset modes, including Relaxation, Work, Reading, Sport, and Sleep modes, though the specific light parameters for each preset are not detailed by the manufacturer.
Convenience Features
The CM011A includes several features aimed at user convenience. The memory function automatically recalls the last used brightness and color temperature setting when powered on, eliminating the need for daily reconfiguration. A timer can be set in 15-minute increments up to a maximum of 60 minutes, after which the lamp shuts off automatically, which is useful for adhering to recommended therapy session lengths. The power source is corded electric, with specifications also listing USB as a connectivity technology, suggesting potential for use with a power bank or USB adapter, though specifics are not provided.
Setup, Support and Ownership
Setup appears straightforward, involving simply placing the lamp on a stable surface and plugging it in. The included components are listed as a power cable. There is no indication of required software or complex assembly. Regarding support and ownership, the manufacturer is LASTAR. The product is designed as a complete unit with no listed upgrade or accessory options. Information on warranty length, firmware updates, or dedicated customer support channels is not provided in the available data. As a single-purpose device, long-term ownership likely revolves around its durability and the longevity of its LED light sources.
What Owners Say
Owner feedback for the Lastar CM011A is overwhelmingly positive, with a high percentage of five-star ratings. Users frequently praise its effectiveness in boosting mood and energy, with some specifically noting benefits during darker winter months. The adjustable color temperature and brightness are highlighted as major advantages, allowing for customization throughout the day. The compact size and modern design are also well-received. Common points of criticism from reviews include the sensitivity of the touch controls, which can lead to accidental changes, and a desire for a longer or more gradual timer function, such as a sunrise simulation. Some users also mention that the lamp is smaller than expected, though they find it still performs effectively.

Who Should Buy It (and Who Should Skip It)
The Lastar CM011A is an excellent choice for individuals new to light therapy or those seeking a secondary, portable lamp. Its strength lies in customization; if you want to fine-tune light color and intensity for different tasks like reading, work, or relaxation, this lamp delivers. The memory function and timer make it convenient for daily, consistent use on a home desk or counter. It’s also a solid pick for users with limited space who still want an effective 10,000 lux device. For more insights on optimizing your home workspace, see our guide on the best desk chairs.
This lamp may not be the best fit for users seeking advanced automation. If you require a lamp with a programmable alarm to turn on at a specific time, or one that features a gradual sunrise simulation to wake you up gently, the CM011A does not offer these functions. Similarly, those who prefer physical buttons or knobs over touch controls might find the sensitive interface frustrating. For individuals needing longer, unattended therapy sessions beyond one hour, the timer limitation could be a drawback. If your primary need is for a very large, powerful panel light for a bigger area, the compact size of the CM011A might not meet your expectations.
Final Verdict
The Lastar CM011A successfully packages the core benefits of light therapy—10,000 lux of full-spectrum light—into a highly adjustable and user-friendly device. Its array of color temperatures and brightness levels, combined with the thoughtful memory function, allows it to adapt seamlessly to different needs throughout the day, from focused work to evening relaxation. The compact form factor is a significant advantage for portability and discreet placement. While it lacks some advanced features like extended timing or sunrise simulation, it excels at providing personalized, effective light therapy in a simple package.
When weighed against its limitations, such as the sensitive touch controls and one-hour maximum timer, the CM011A’s strengths in customization and convenience make it a compelling option. It is a well-rounded product that delivers on its primary promise of mood and energy enhancement through bright light. For anyone looking to explore the benefits of light therapy at home without a large investment in space or complexity, the Lastar CM011A is a versatile and capable choice worthy of consideration.

FAQs
How close do I need to sit to the Lastar CM011A for it to be effective?
To receive the full 10,000 lux of light intensity, you need to position yourself at the manufacturer’s recommended distance. The exact distance is not specified in the provided data, but user reviews confirm that achieving the brightest setting requires sitting quite close to the lamp. For lower brightness levels, you can sit further away. It’s important to follow the positioning guidelines to ensure you are getting the intended therapeutic benefit.
Does the memory function save all settings?
According to the manufacturer’s description, the memory function remembers your last brightness and color temperature setting. This means when you turn the lamp off and back on, it will return to the specific combination of warmth/coolness and intensity you were using. It does not appear to save timer settings or specific mode selections based on the available information.
Can I use this lamp with a USB power bank?
The product specifications list “USB” under Connectivity Technology and its power draw is only 12 watts, which suggests it may be compatible with a USB power source. However, the manufacturer explicitly states the power source as “Corded Electric,” and the included component is a power cable. It is not definitively confirmed whether it can operate via a standard USB port on a computer or a power bank without the provided cable and adapter.
What is the difference between the color temperature and the ‘modes’ like Reading or Work?
Color temperature is a precise measurement of light warmth (in Kelvins) that you can manually select. The ‘modes’ such as Reading, Work, or Relaxation are likely preset combinations of a specific color temperature and brightness level optimized for that activity. The manufacturer does not provide the exact settings for each mode, but they offer a quick way to switch to a recommended lighting profile without manually adjusting both temperature and brightness separately.
