When choosing a grow light for your indoor plants, safety is just as important as efficiency and effectiveness. You might be wondering—are grow lights safe for humans and pets? Can they cause cancer, burns, or eye damage? Fortunately, Soltech grow lights are designed with safety in mind, ensuring they provide the perfect light for plants while remaining harmless for people and pets.
Let’s break down the science behind PAR wavelengths, how our full-spectrum lighting works, and why Soltech grow lights are completely safe for home and commercial use.
What Makes a Grow Light Safe? Understanding PAR Wavelengths
Unlike UV tanning beds or industrial lighting, grow lights are designed to mimic natural sunlight for optimal plant growth. At Soltech Solutions, we use a full-spectrum light source focused on PAR (Photosynthetically Active Radiation) wavelengths, which fall between 400-700 nanometers (nm).
This spectrum covers:
🔵 Blue Light (400-500nm) – Supports strong roots and compact foliage.
🟢 Green Light (500-600nm) – Helps plants efficiently absorb light while maintaining natural aesthetics.
🔴 Red Light (600-700nm) – Encourages flowering, fruiting, and overall plant maturity.
What’s NOT Included?
Our lights do not emit excessive UV (ultraviolet) or infrared (IR) radiation, which can be harmful with prolonged exposure and is often associated with skin damage, eye strain, or overheating. Instead, we focus on safe, plant-optimized wavelengths within the PAR spectrum (400-700nm), ensuring healthy plant growth without any risk to people, pets, or home interiors. This means you can enjoy thriving greenery in your space without worrying about harmful radiation, burns, or unwanted heat buildup—making our lights a safe and effective solution for both plants and living spaces.
Safe for Humans: No Harmful UV, No Risk of Cancer
One common concern is whether grow lights can cause skin damage or increase cancer risk—similar to prolonged UV exposure from the sun. Rest assured, Soltech grow lights are safe for human exposure. Here’s why:
🚫 No Excessive, Harmful UV Radiation – One of the most common concerns with grow lights is UV exposure. While ultraviolet (UV) light is a natural component of sunlight and can have some benefits, prolonged exposure to certain UV wavelengths can lead to sunburns, skin aging, and even skin cancer. Some LED grow lights emit UV radiation, raising concerns about long-term exposure in home environments.
At Soltech Solutions, we prioritize safety and plant health. Our grow lights have been independently tested to assess UV risk:
• UV Type: Primarily UVA (350-399 nm)
• No UVB (280-315 nm) or UVC (100-280 nm), which are the most harmful wavelengths
This means our lights do not produce enough UV radiation to be harmful, making them safe for daily use in your home. You can enjoy healthy, thriving plants without worrying about skin damage, eye strain, or health risks—just full-spectrum, plant-optimized light designed for both you and your greenery.
🔆 Designed To Mimic Natural Daylight – Soltech grow lights emit safe, full-spectrum light that closely resembles natural daylight, falling within the visible light range without excessive exposure to harmful UV or infrared rays.
Take it from me and my coworkers—we spend our 9-5 workdays, Monday through Friday, under dozens of Highland™ track lights, and they provide comfortable, natural-looking illumination without any negative effects.
🌞 Comparable to Sunlight, But Safer Indoors – While natural sunlight contains UV rays that can cause skin damage over time, Soltech grow lights provide all the benefits of sunlight for plants—without the health risks. Unlike the direct, prolonged exposure plants receive, you won’t be sitting directly under the light like a plant would, so there’s no need for sunscreen. However, if you feel more comfortable applying it, you absolutely can—just know that our lights are designed to be safe for everyday indoor exposure without the risks associated with UV radiation.
🔥 Infrared (IR) Light: Safe, Gentle Heat for Growth – The small amount of infrared (IR) light is harmless and is actually beneficial for plant growth. It produces a gentle heat effect that helps encourage healthy growth and cell function in plants, improve nutrient absorption and water retention, and support strong root development.
Interestingly, research suggests that the red light used in our spectrum may offer benefits beyond plant growth. Studies show that red light therapy can:
✨ Promote collagen production for healthier, more youthful skin
✨ Reduce inflammation and speed up wound healing
✨ Improve circulation and support overall skin health
In fact, a NASA-backed study* found that red and infrared light can help stimulate cell regeneration and tissue repair in human skin. While our grow lights aren’t designed for skincare, their safe spectrum means they won’t harm your skin, eyes, or overall health—even with long-term exposure.

Safe for Pets: No Harmful Radiation or Heat Emission
If you have curious cats, dogs, or other pets, you’ll be happy to know that Soltech grow lights are 100% pet-friendly. Unlike older grow lights that emitted excess heat or UV rays, our modern LED technology keeps pets safe by:
✔️ Producing Safe Light – Our LED grow lights are designed not to emit harmful radiation, ensuring they won’t overheat or burn surfaces, plants, or paws. However, if you notice leaf burn on your plants, your grow light may be positioned too close. To ensure proper placement, refer to our grow guide, which includes recommended hanging heights for each product: Vita Grow Guide.

✔️ No Flickering or Eye Strain – Unlike cheap fluorescent grow lights, Soltech lights operate at a consistent wavelength with no flickering, ensuring eye comfort for both humans and pets. If you do experience any flickering, please reach out to us at hello@soltech.com, and we’ll be happy to assist with a product warranty replacement. Your satisfaction is our priority, and we want to ensure you have the best experience possible!
✔️ Full-Spectrum, Plant-Optimized Light – Our grow lights provide the best light for plant growth while remaining completely safe for all living beings in your home.
Many of our customers have noticed that their cats love sunbathing under the Vita™ Grow Bulb, soaking in its warm, cozy light. Some have even set up a Vita specifically for their cats, creating a mini sunspot for them to lounge in—proving that our grow lights aren’t just great for plants, but also for keeping furry friends happy and relaxed!

No Risk of Burns: LED Technology vs. Traditional Grow Lights
Traditional HID (High-Intensity Discharge) and HPS (High-Pressure Sodium) grow lights generate significant heat, posing a potential burn risk for plants, pets, and home interiors. HPS lighting, another older technology, was widely used for growing but shares the same heat and efficiency issues as HID.
According to our co-founder, Mike Planer, the biggest drawback of fluorescent lighting is its untargeted and inefficient spectrum—while some models may provide low-level support, LEDs far outperform them in terms of efficiency, longevity, and plant growth benefits. Since grow lights typically run 10-16 hours per day, LED technology significantly reduces energy consumption, making it a cost-effective investment that pays for itself over time.
Why Soltech LED Grow Lights Are the Best Choice:
✔️ Energy-Efficient & Cool to the Touch – Unlike older grow light technology, our LEDs stay relatively cool if placed on a timer, eliminating the risk of burns to plants, pets, or home surfaces.
✔️ Safe for Long-Term Use – Our lights are designed for continuous operation, so you can keep them running throughout plant growth cycles without excessive heat buildup. We also offer timers and can provide lighting recommendations for optimal use.
✔️ Dimmable for Extra Control – Many of our grow lights come with dimming capabilities, allowing you to adjust light intensity to create an indoor environment that works for both plants and people. The Grove™ Bar Light features touch dimming, making it easy to customize the ambiance and aesthetic of your space. Additionally, the Highland™ Track Lights and Vita™ Grow Bulb are compatible with dimmable fixtures and timers, giving you even more control over light levels, plant growth, and energy efficiency.
