The Solar Flare has equal build quality with the Advanced Platinums P300 model and the PAR output comes in second on my list. It is also stated by the manufacturer that the life expectancy for their OSRAM SSL chips are 80,000 hours which is excellent compared to the standard 50,000 hours from other brands. Their LED grow lights for growing marijuana are great for beginners and experts alike. I’ve have nothing but praise and the results I’ve seen firsthand are impressive to say the least.

My 2 cents: I like the Viparspectra brand as a whole, they make great LED grow lights for cultivating marijuana. The 300w Reflector series has a quality build, good overall design, proven performance backed by great customer service. The daisy chain option and 5w diodes are good options because you can add an extra light and the diodes are underpowered which will increase its lifespan. If you are looking for a dependable full spectrum grow light that performs great and is still affordable, this is your light. My rating 4.6 outta 5.

My # 5 Pick – Proven Results

My 2 cents: I really like the company Meizhi because they rarely have any problems and they are excellent LED grow lights for marijuana. Their 300w model is a very good starter light with the 5w diodes. The build quality and performance are hard to beat. I have had no problems with mine and the reviews say the same thing, so the 1-year warranty was never a drawback because I’ve never had to use it. If you want a quality light that gives great results, this one will not disappoint. My rating 4.5 outta 5.

New Addition

MaxBloom X4 Plus Full Spectrum COB LED Grow Light

MaxBloom X4 PlusFeatures Include: 12-Band Full Spectrum, UV/IR, Veg/Bloom Switch, COB & 5-Watt Diodes, 2 Cooling Fans w/Aluminum Heat Sinks, 5-Year Warranty, 200-Watt Output with PAR at 24" Height being 580 µmol m−2s−1.


MaxBloom X4



My 2 cents: I really like MaxBlooms X4 Plus for growing cannabis. Combining the standard LED's with the COB for their proprietary 12-band full spectrum is remarkable. They should guarantee their high yield claims because mine showed considerable gains over some of the other lights on my list. The light runs quiet and cool, and its priced to sell. Some other good features are that it's waterproof and it comes with a 5-year warranty which means they stand behind their product. If you are looking for top-notch performance for a very reasonable price, this light is exactly what you have been looking for. My rating, 4.9 outta 5.

    LOL, well, I really didn’t realize that so much went into growing marijuana or that there would be so many different types of options just the for lights! Interesting to see all the different options here and I am also surprised in the range of pricing. Some of them get a bit expensive!

    • Karl Hosch

      Yes, the options are plenty but I feel what I put out there is representative of the best lights available for the price. You’d be surprised at how expensive some of the other ones are that are not on my list…..thousands for just one light with no guarantee. That’s why I don’t put too much value into some lights because you put all your funds into one light and what happens if you damage it or the like. You’re out that much money with no help from the seller. That would not be good. Thank you for the comment, feel free to come back anytime. 

  2. Dani

    I can’t believe how many options there are to choose from. I like the the beginner level 300-watt ones that are daisy-chainable. They seem simple enough for me as I am just getting started.

    I was just wondering how they mount. Are they easy to mount overhead? And how far above the plants should they be mounted? Or do they not need to be overhead at all?

    Thanks! Great post!

    • Karl Hosch

      Yes, you do have to hang them. They hang down from above either from your grow room ceiling or tent. Almost all of them come with mounting hardware and they are easy to install. 

       Depending on the stage of your plants, the height can be anywhere from 12 to 24 inches. I’d start at 12″ then watch every hour for signs of bleaching. If you see and raise the light up 6 inches and try again. You’ll be able to tell within checking on them a few times whether or not the light needs to be raised. 

      Keep me posted on how your grow goes and if you have any more questions, please feel free to come on back anytime. Thank you!

    Wow, so many options to choose from, and these are only at a beginner’s level! I like how there is a reasonable price range in order for me to get started without breaking the bank in the process.

    What are some of the key differences that take the lighting to the next level? Obviously I would start here and learn to build with starter kits, but I’m curious to know where the path leads to as I increase my skills…

    • Karl Hosch

      What separates the lights is power. Power drives the growth and it is a throwback idea from the older types of lighting like fluorescent, metal halide, and high pressure sodium. As you progress, you will need to refine your technique and once you are comfortable, you size up your operations by adding more lights with more power but it depends on how far you want to take those skills. You can go to a 96x96x72 grow room, a cargo sea train, rental houses, or to a secure Industrial building. You’ll be doing the same thing you would with the starter kit but on a larger scale. So, in short, power separates one level from the next. 

  4. Nice article on the technical lighting required to grow indoor plants.

    It was nice that you gave an opinion on each product and you certainly have covered a range of products which is great.

    We are renovating an old house at the moment and the main electronic connections to our house overload easily. I was just wondering if this was all the electronic devices required to grow indoor plants or is it best to hire an electrician to connect an independent circuit for the plants to fun off combined with their own safety switch?

    • It depends on how many lights you plan on using. if you are going to run a couple 300-watt lights then I would worry much but if you plan on running 6 1200-watt or more lights then I would run a separate circuit. When you say “overload” easily do you mean the circuit breaker gets tripped? If so then I would have an electrician run a separate one anyways because depending on what types of plants you are growing,just a few hours without light can adversely affect the health of the plant(s). In order to meet building code requirements in Australia, a separate circuit breaker would be mandatory. So in short, I would take the stress out of the grow operation and call an electrician. I hope I answered your question and I thank you for your comment. Feel free to come back anytime if you have any questions. Cheers!

  5. My Life as a Mom

    Hey. Really great Review post. So many to pick from and it’s really great that you put so many different products and your opinion on them. If someone would want to buy, they can actually pick the best for their needs. Thanks for the post and the info. Have a great day.

    • Karl Hosch

      Thank you, that was my intent. There are soo many different people growing herbs, fruits, vegetables, houseplants and medicinal plants, I thought it best to present an array of options instead of just one or two. I thank you for your comment, feel free to come back anytime or contact me if you have any questions.
