In-depth 7 Top Rated Grow Lights For Greenhouse Reviews
1. Monios-L LED Grow Light Strips for Plants 2FT, 60W – Best Grow Light for Indoor Greenhouse
This 2ft grow light set from Monios-L is the best grow light for greenhouses of all sizes. Each 10W T-5 full-spectrum LED bulb in this set can deliver high energy efficiency equivalent to a 100W conventional light and last for 50,000 hours.
This package comes with all essential components and accessories for setting up an indoor artificial lighting system, including 6 LED bulbs, 3 power cords (59 inches), 18 pads, 18 cable ties, 5 connecting cords (20 inches), 6 small connectors, and 6 installation accessories (screws and clips).
This light set meets the PAR (Photosynthesis Active Radiation) rating for most plant growth in the greenhouse. Thus, it is suitable for plants, like hydroponics, green leafy vegetables, and microgreen.
These lights offer full-spectrum lighting like natural sunlight, ranging from 380nm to 780nm. Even on snowy or cloudy days, your plants can always absorb enough light for their lush growth.
Even if you have a big greenhouse with plants of many types and growth stages, you can extend this artificial light source by grouping every 10 lights into 3 groups with seamless connectors and electrical cords.
In addition, every bulb has an independent on/off switch, allowing you to control the lighting duration in the same grow room. For example, short-day plants like chrysanthemums need under 12 hours of light daily, while long-day plants like lettuces or potatoes need 14 to 18 hours of light daily.
2. EZORKAS GL07 9 Dimmable Levels Grow Light with 3 Modes Timing Function – Best with auto-cycle timer
Unlike the above Monios-L item, this light set from Ezorkas offers 3 color choices, namely full-spectrum, red and blue, sunlight white. How can you pick up an option for your plants?
For example, you can use the red-and-blue option (with 660nm for red, 460nm for blue) in the flowering stages of your plants to get veggies with more leaves or sweeter fruits. Plus, the full-spectrum option is for general cultivation. You should place these bulbs 12-18 inches away from your seedlings.
Plants need rest, just like humans, to transport nutrients into their extremities. That said, you should not leave grow lights on 24/7. But how can you adjust your artificial lighting system when you are not at home?
First, you can use the built-in auto-cycle timer to let these greenhouse grow lights turn on every day, with the time ranging from 10 minutes to 23 hours 50 minutes.
Second, you can customize the lighting level by adjusting the bulb’s dimmable mode with 10-100% brightness settings. More specifically, there are 9 modes for the red-and-white option, 5 modes for the sunlight white option, and 4 modes for the full-spectrum option.
Another notable advantage of this grow light set is that it is designed for efficient heat dissipation all year round. Its high-quality aluminum casing can dissolve heat fast before adversely affecting your plants. Thus, this case helps reduce overheating while extending the lifetime usage of the bulbs.
3. Cholas 36W 132 LEDs Auto ON & Off Function – Best price
With this 36W Cholas LED light set, you can grow many plants in a greenhouse, like orchids, houseplants, or some vegetable and fruit crops, all year round without worrying about harsh weather elements. This artificial lighting system is also helpful for emergency seedlings, ensuring stocky, lush seedling seeds.
This energy-efficient LED lighting system offers you full control of lighting duration and intensity for enhancing the photosynthesis process indoors. The two-way memory function allows you to pick up the lighting duration of 3 hours, 6 hours, and 12 hours based on the growth stages of your plants.
You can set it up once, and it will turn on and off automatically every day.
Also, you can adjust the lighting condition with 5 dimming levels and 3 independent on/off switches. Besides indoor planting, these LED lights can also be used as a work light for home and office environments.
Heat dissipation is an essential factor you should not neglect when picking up the best grow lights for greenhouses. Since these LED lights produce minimum heat, you can use them for your small greenhouse without overheating your plants.
4. Barrina 144W Full Spectrum Sunlight Grow Light Bulbs – Best LED grow lights for greenhouse
Apart from the grow light type, PPFD (Photosynthesis Photon Flux Density) says a lot about lighting efficiency. This specification indicates the amount of light that your plants actually absorb in the PAR zone or the number of photosynthetically active photons that are spread on a specific surface in a second.
Thus, the higher the PPFD, the higher lighting efficiency the grow light is, and the less waste energy used for lighting.
These super-bright Barrina grow lights have a wide and high PPDF range from 69.3 to 210.7 μmol/s.m², which is suitable for various types of plants. As stated by the manufacturer, your plants can absorb over 95% of light. You can even enhance the light efficiency from 17-20% with the reflector.
About its lighting efficiency, this LED supplemental greenhouse lighting system uses a total of 576 LED lights but consumes only 144 watts per hour. It can replace 800W general grow lights.
These Barrina lights are versatile because they can be used for various indoor planting environments, like grow tents, hydroponics, grow shelves, greenhouses, etc. Their sunlight white color soothes your eyes and doesn’t make you feel dizzy or uncomfortable when watering or taking care of your plants daily.
5. Roleadro 75W LED Grow Light for Indoor Plants – Great light with diverse spectrum choice
You can still grow and harvest fresh greens for your salad bowls on the freezing winter days, thanks to these stunning 75W Roleadro grow lights. These lights can be used for many indoor plants in soil or hydroponics in an indoor garden, a greenhouse, a vertical mini-farm, grow room, or grow room.
And since they come from Roleadro – a well-known brand with over 11 years of R&D and manufacturing LED light products, you can safely use these grow lights as a natural sunlight replacement. These indoor lamps have been certified by CE, FCC, PSE, and ROHS.
The main reason that makes this grow light set suitable for small space planting environments is that it has an excellent heat dissipation design.

Besides, these Roleadro LED lights offer a diverse spectrum choice of 460-465nm, 620-740nm, 6000-6500k wavebands to promote their growth. Thanks to this spectrum range, you can maintain a lush indoor garden of various plants in the coldest winter months, from temperate vegetables and herbs to tropical plants.
6. LBW LED Grow Light with Stand Full Spectrum 150W – Tripod stand for movement
This compact LBW grow light can be applied for family planting demands, from small balcony flower seedling/breeding to large and tall plants. Furthermore, it offers full-spectrum lighting capability with excellent energy efficiency. It consumes 30 watts per hour and provides lighting equivalent to a 150W HPS or HID light.
This LED grow light comes with a tripod stand extending from 15 inches to 48 inches or adjusted at different angles depending on your plant’s size and lighting requirements.
Having a stand also means you don’t need special tools or extra accessories to install the lamps on the walls. Just adjust the height and the angle of the tripod, then place it anywhere you want or move it around the greenhouse so that all your plants can get the most of this artificial sunlight source.
You can also use it as a hanging light or use 4 zip ties in the product package to mount the bulb in any position you want.
7. GE BR30 LED Light Bulb for Indoor Plants, Balanced Spectrum, 9-Watts – Best for mini greenhouse
If you have a mini greenhouse, purchasing single light bulbs can save your budget better than a whole bulky lighting system. This 9W GE BR30 grow bulb has a high output PPF of 16 μmol/s.m² and a balanced spectrum, making it highly advisable for general budding, flowering, seeding, and fruit production.
Each package includes one bulb. So, you should estimate the size and structure of your greenhouse to get an appropriate number of bulbs.
1. What’s the difference between grow lights and regular lights?
Grow lights have some differences from standard LED lights, including higher heat emission, higher energy consumption, lower energy efficiency, a shorter lifespan.
Since these lights are designed to boost the growth of plants and flowers, they can spread light on the same wavelengths as natural sunlight. These lights are more affordable but harder to be found than regular lights.
2. What color grow light is best?
Blue is the best color for a grow light. This color can easily be absorbed by chlorophyll and converted into energy through photosynthesis.
3. Are purple grow lights better?
Although purple grow lights have a limited effect on plant growth when used standalone, you can combine them with red and blue ones to enhance the color, scent, and taste of plants.
4. How many lights do I need in my greenhouse?
For optimum growth, a greenhouse needs at least 6 hours of direct or full-spectrum light. If it can’t receive enough natural sunlight, you should use additional supplement lighting like grow lights.
5. What type of light is best for growing plants indoors?
Full-spectrum light is the best option for growing plants and flowers indoors. This light type provides the perfect balance of cool and warm light like the solar spectrum in nature.
6. What is the difference between red and blue LED grow lights?
Both red and blue LED grow lights are essential for the lush growth of plants, and these two lights should come together for the best plant growth.
But red lights are more important in the flowering stages of plants. They result in more robust development, more leaves (for veggies), better fruit quality (for fruit trees), or better bloom production (for flowers).
7. Should I leave a grow light on 24 hours?
You should not leave a grow light for 24 hours since all plants need darkness to rest. In the darkness, they take a break while transporting nutrients into their extremities.

My Top Pick
The best grow lights for greenhouses are essential supplements to missing sun rays, especially if you live in the North or have limited natural sunlight exposure in your indoor garden.

Yet, make sure you pick a high-quality item like Monios-L LED grow light strip. This light set is durable and energy-efficient and comes with all necessary accessories and tools for quick installation.
