Moreover, it effectively reduces the harmful effects of blue light on the eyes. The working heat of the lighting device is quickly transferred to the air through natural convection, and the heat dissipation is faster and the service life is prolonged. SANSI light intensity is always than others with the same power. Sufficient light intensity ensures healthier plant growth and prevents plants from becoming too elongated (manifested in plants having long, thin stems without proper flower or fruit development). How do I determine light needs, height, and duration for my plants? Check your plant's Daily Light Integral (DLI) and use our PPFD values at different heights to calculate optimal lighting duration. How does this light compare to red and blue spectrum lights? Our 4000K full-spectrum light mimics natural sunlight, suitable for various plants without causing light pollution. Ceramic construction ensures durability and safety. How energy-efficient is this grow light? Will it significantly increase my electric bill? Our LED grow light consumes 36W, costing approximately $1.56 per month (12 hours/day) at $0.12/kWh. LEDs like ours are highly efficient, providing cost-effective lighting solutions for plant growth. I prefer growing tropical plants. Is this light suitable for that? Yes! Our full-spectrum light mimics natural sunlight, essential for tropical plants. With a high PPFD of 265.58 μmol/s/㎡@1ft, it promotes fast photosynthesis and robust growth, evenly illuminating plants for compact, symmetrical growth. What's the best light for indoor plant growth? Plants need specific light at different stages -more blue for growth, more red for flowering. Our Full Spectrum Lights meet these needs and provide optimal conditions. Adjust duration and maintain optimum height above plants for even growth. 36W Grow Light Bulbs 10W Grow Light Bulbs 32W Grow Light Bulbs 5W Pot Grow Light 10W Pot Grow Light 10W Puck Grow Light 80W Wing Grow Light ## Features - 4000K DAYLIGHT: Imitate the solar spectrum, customize a more ideal full life cycle full spectrum supplementary light program, covering the entire visible spectrum of 400nm-780nm; Color rendering index Ra is close to 100, infinitely close to natural light, suitable for every cycle of plant growth, effectively promotes plant growth, and improves crop yield and quality - SECONDARY OPTICAL DESIGN: PPF: 65.6 umol/s, PPFD: 265.58 μmol/s/m² @ 1ft.

They are all excellent bulbs, so bright it is annoying to have them pointed at your eyes. I was attracted to the Sansi brand thanks to a few online reviews, especially some that used their own spectrometers to confirm that these give a proper full spectrum including a little UV. I like to think my bird likes it too since she can see UV! I wonder if the UV helps with winter depression?In summary:I recommend the 15W for individual low-light houseplants, like a mini moth orchid, succulent, or mini African violet. I recommend the 24W if you have a small collection of plants. I recommend the 36W if you have a medium collection or want to grow a fruit/veg.. I recommend multiple 36W if you have a large collection or a small tree, but if you have that many plants you probably already know what you are doing. ;)Of note:Of note is that the bulbs do get hot after running about 12hrs a day, so it hurts a little to touch the diodes directly, and do not put them in lampshades that would restrict airflow. They do not run hot enough to affect the plants whatsoever though. I have to put my hand 1 inch away from the diodes before my hand detects it as being hot. I think the passive vents do a great job of directing the heat up and away rather than down towards the plants.Also of note is that there is an audible coil whine when any of the bulbs are on. This is not loud or obtrusive (I regularly have one about 3ft from me when I am studying), but it is noticeable if you have young ears.It is also worth noting that the light cone is fairly narrow/focused, so plants directly under the bulb get significantly more light than those around the periphery. This is not a bad thing; it means more of the light is efficiently being beamed on your plants instead of scattering around the room.Below is a comparison of my personal experience with the 3 sizes:The 15W was excellent for a tall desk lamp with a few mini African Violets huddled around it. It was insufficient for outdoor plants that like full sun such as Egret Orchids.I upgraded to a 24W once my plant collection grew to the dozen mark, so I could have a larger illuminated space to work with. Of note is that this bulb was visibly warmer in color than the 15W or 36W. It reminded me of a nice incandescent bulb's glow. I am not sure if this is a consistent thing with the 24W or if it was just my bulb. Otherwise, the 24W was actually my preference for houseplant use with my personal setup.I bought the 36W for a friend to use in a fish-tank sized terrarium, again, for the wider radius able to cover more plants. It is strong! It would be interesting to see if more outdoor semi or full-sun type plants would be satisfied by the 36W; it is a very bright bulb. As is, my low-light houseplant African violets needed to be placed an extra foot away from the bulb to stop from getting sun burn or bleaching. I would mention that the bulb is quite heavy at this point, so if you are using a flexible goose-neck lamp, make sure it is nice and stiff or it might sag under the weight.Tip:If you have a proper light sensor, it is super handy when setting up your plants around your new bulb. I resorted to the free Arduino Science Journal app on my phone to compare light intensity (in lux units), and using recommended lux levels from google for my particular plants.I get about 22K lux directly ~1ft below the 36W bulb, for example, but about 8k lux ~2ft directly below. I currently have my mini african violets arranged in a ring of ~2ft diameter, about ~1.6ft below the light. This gives them the recommended ~7k lux of light according to google. ### ⭐⭐⭐⭐⭐ Awesome lights and customer service *by on Reviewed in the United States December 30, 2025* I’ve been using the SANSI 34W Grow Light for about 4 years now, and it has been absolutely awesome. This light has allowed me to grow massive, healthy plants completely indoors with strong growth, great leaf size, and consistent results year after year.The light output is powerful for its size, energy-efficient, and reliable long-term—I’ve never had issues with it burning out or losing intensity. It’s perfect for houseplants and makes a noticeable difference in plant health and growth, especially if you don’t have ideal natural lighting.If you’re serious about indoor plant growth and want something dependable that actually works, I highly recommend the SANSI 34W grow light. It has more than proven itself over time. 🌱💡.Last week I had to use their customer service for blown bulbs and it was top notch service and hassle free replacement. ### ⭐⭐⭐⭐⭐ Stopped working *by on Reviewed in the United States June 9, 2026* Not sure if I got faulty ones, but both bulbs blew within almost two months. I purchase these and put them on a hanging light and they both went out. I thought it was the cord so I replaced it and nothing. Swapped bulbs and it worked. Contacted Sansi so we’ll see what happens. I love their other products so this makes me a little sad.Edit: they’re sending out two new bulbs! ## Frequently Bought Together - SANSI Grow Lights for Indoor Plants Full Spectrum, 36W Grow Light Bulb (400 Watt Equivalent) with Optical Lens for High PPFD, PPF 65.6 umol/s LED Energy Saving Plant Light Bulb for Seeding and Growing - DiCUNO Hanging Lantern Extension Cord Cable, E26 Pendant Light Socket On Off Inline Cord Switch Control Lamp, Switch Close to Polarized Plug, 13 Feet, White, 1-Pack - Grow Light Bulbs, Briignite LED Grow Light Bulb A19 Bulb, Full Spectrum Grow Light Bulb, Plant Light Bulbs E26 Base, 11W Grow Bulb 100W Equivalent, Grow Light for Indoor Plants, Seed Starting, 2Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/62427085-sansi-grow-lights-for-indoor-plants-full-spectrum-36w-grow](https://www.desertcart.hr/products/62427085-sansi-grow-lights-for-indoor-plants-full-spectrum-36w-grow) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-23*
