Optic Slim 720S Dimmable LED Grow Light VS Lex Grow 720W Commercial LED Grow Light
Cultivating crops under artificial lighting in closed and fully controlled environments is a method with growing benefits and global impact.
Industrial indoor agriculture could become the main factor keeping famine and related conflicts at bay. With rising populations, declining agricultural land, pollution, global warming and migration, it will become even more important in the future to grow crops in a reliable, predictable and efficient manner.
A key factor in the success of indoor plant growth is the efficiency of the lighting system in inducing plant growth when compared to sunlight.
To build a very efficient lighting system, some basic scientific concepts should be known
Plants grow through a process called photosynthesis, which converts electromagnetic radiation — light — into chemical energy needed for growth and development. The other ingredients needed are carbon dioxide (CO2), nutrients and water. The process itself is not particularly efficient, converting only 4 to 6 percent of absorbed radiation into chemical energy, but this is the engine that powers most life on the planet.
Are LED’s really as good as HPS grow lights?
When it comes to PPFD and coverage, LED grow light’s can stand against some of the strongest HID’s around. Moreover, they’ll give you the same intensity and coverage- if not more- while using less energy and giving off much less heat.
And reason LED’s are able to do so is simple: electricity.
HID bulbs rely on the heating and chemical reaction of metals and chemicals in order to give off light. Those bulbs have a limited PPFD output due to the amount and size of the chemicals inside. And those bulbs take a certain amount of energy to make that reaction happen. Moreover, it’s the heating of those chemicals that gives us light, and a byproduct of that light is heat.
But in LED’s energy is used to illuminate a certain number of diodes electronically, and those diodes take a very minimal amount of energy to run. As we’ve mentioned, it’s all of those low wattage diodes shining together that give you the light you need to grow.
Take a 400w HPS grow light that gives off a max PPFD of 534 from one bulb.
Compare that to a 240w LED with over 700 diodes with a max PPFD of 648.
The LED uses 160w’s less than the HID yet gives off 166 PPFD less.
And the great this is that in a sense, there’s no limit to how powerful an LED can be. With more diodes you can increase intensity, and only raise energy cost minimally. Compare that to HID’s where you’ll have to increase energy costs by 50–100% and still lose intensity.

Let the act of changing light bulbs be a distant memory.
What makes the best grow light?
To help you choose from the wide variety of shapes, sizes, wattages, prices, and more. that can be found on the Internet, let’s see what are the really important criteria to take into account before buying.
- The price will depend mainly on the quality of manufacture, but also on certain options which can bring a real advantage to the use.
- For the panels, some models offer fans associated with aluminum heatsinks or the possibility of chaining several panels in the same installation.
- For lamps, the options that can influence the price are the number of heads, switches, and the ability to vary the lighting intensity.
- For bulbs, it is mainly the quality of the heatsinks that can make the difference.
- Be careful to adapt the power of your installation to your needs. Indeed, it will be very different for a small bonsai or a palm tree over a meter high.
- An important selection criterion is also the warranty period for the equipment. The longer it is, the more confidence the manufacturer has in the origin of the parts and their manufacturing and testing process.
Conclusion
LED lighting can be complicated, but it isn’t impossible. You simply need to learn a little about your options and choose the best lighting for your situation. Even if you get it wrong, you’re likely to end up with something.
As long as you don’t burn your plants.
