- Changes in color temperature and intensity
- Includes UV rays
Remember, the term “full spectrum” might be used flexibly by manufacturers, as there is no standard definition that dictates the exact qualities these bulbs must have. Therefore, it’s always important to look at the specifications of individual products to understand their characteristics.
Will full-spectrum lights tan you?
When considering whether full-spectrum lights can tan you, it’s pivotal to understand what “full-spectrum” encompasses. Full-spectrum lighting is designed to closely replicate the light from the sun, covering a range of wavelengths across the visible, infrared, and ultraviolet spectrums. However, the ability to tan is predominantly tied to the presence of UVB rays.
Natural sunlight emits both UVA and UVB rays, with the latter being primarily responsible for triggering the tanning process in your skin. While full-spectrum lights may include some UV wavelengths, they typically lack the intensity and specific UVB range necessary for tanning.
Key Points:
- Full-spectrum lights: Mimic natural sunlight but may not always include sufficient UVB.
- UVB rays: Essential for skin tanning, these may be minimal or absent in full-spectrum lights.
To directly answer your question, the likelihood of you getting a tan from full-spectrum lights commonly available for home or office use is minimal. Such lights are designed more for functional and aesthetic purposes rather than tanning. If the full-spectrum light source does include UVB rays, it might be possible to tan, but this is not the norm for typical full-spectrum products. Additionally, using any artificial lighting for tanning should be approached with caution due to the potential for skin damage. It is also worth noting that the goal of full-spectrum lighting is usually to provide a natural quality of light for well-being and visual acuity, rather than skin tanning.
Always check the specifications of your full-spectrum lighting to understand its UV output before considering it as a means to tan. It’s important to prioritize safety and skin health. If you seek a tan, more conventional methods such as controlled sun exposure or using designated tanning equipment would provide the UVB rays needed for your skin to tan.

When you use full spectrum lights, your indoor plants can grow as they would under direct sunlight. The inclusion of not just the visible spectrum but also some portions of the invisible spectrum, like ultraviolet (UV) and infrared (IR) light, can be beneficial for different growth stages.
If your plants are not exposed to natural sunlight, full spectrum grow lights can serve as a substitute. However, different plants have varying light requirements. Typically, a plant might need about 16 to 18 hours under full spectrum lights if no supplemental sunlight is provided. The exact duration depends on whether a plant prefers low-light or high-light conditions.
Remember, the efficiency of full spectrum lighting also depends on the quality and spectrum coverage of the grow light you choose. In comparison to traditional LED grow lights, full spectrum grow lights often use a phosphor coating to enhance the spectrum of light emitted. This technology is essential in simulating natural sunlight and supporting the growth and health of your plants indoors.
How do I know if my LED bulb is full spectrum?
Identifying if your LED bulb is full spectrum is crucial to ensure you get quality lighting that closely simulates natural sunlight.
Check the Color Temperature: Full spectrum bulbs typically have a color temperature around 6500K. This is considered the equivalent to daylight under a clear sky.
Look at the Color Rendering Index (CRI): The CRI is a metric that measures how accurately a light source displays colors when compared to sunlight. For a bulb to be considered full spectrum, it should have a CRI rating of 95 or higher.
- Examine the Wavelength Range: A true full spectrum bulb will emit light at all wavelengths from 380nm to 760nm. This includes both visible and some invisible light (like UV light).
