LEDs: What are they?

Light emitting diodes (LEDs) are a type of lighting used in plant cultivation. LED grow lights utilize hundreds these surface semiconductors to produce varied wavelengths of light which work together to create the ideal color spectrum for maximum photosynthesis and growth. Recent technological innovations have made them

LEDs: The Benefits

There are several advantages to LEDs that should make you consider them over CMH and HPS lamps. In addition to being lightweight, LEDs operate much cooler than other types of lighting, and this can be particularly important when climate is a factor. LEDs also use significantly less energy than other types of lighting which is great for the environment and your power bill.


The nine Best LEDs for your Cannabis Grow


1. Fluence Spydrx Plus 660

Our best of the best pick, the Fluence Spyder 660 is definitely one of the most robust full-spectrum LED lights on the market. Providing an even light spread and delivering a PPFD of over 900, this light is ideal for nearly any grow operation. With its sleek, low profile design, this light is as much of a showpiece as it is a high-quality LED. Also, each Fluence LED is made to order! Think Fluence LEDs for your commercial cultivation or hobby grow needs!

“Since switching over to the SPYDRx Plus, I have been very impressed. The light distribution is fantastic. The plants love it, producing higher quality flowers. I am a veganic grower, and using this highly efficient lighting system is an energy saving plus…excellent product.” – Customer Review

“These are the real deal. Halfway though one run I could tell they were going to replace my 600w HPS setup. There is less stretch, the flowers are closer together, and the buds are more dense. I’m blown away by these. I’m cheap and still would have paid double. There’s nothing else like it on the market. Instead of hot and cool spots from reflectors and a single light source, I have perfectly even light intensity from multiple sources. Im buying their RAZRX and Ray series lights for my other lighting needs. I’ll never buy another set of bulbs again. I will definitely buy whatever Fluence sells in the next decade to replace my aging SPYDRX Plus.” – Customer Review

More About LED Lights for Your Cannabis Grow

There was a time when very few growers would consider, let alone recommend, LED lights for growing cannabis. But as technology advances, manufacturers have been able to refine the design of these light emitting diodes to provide a high quality light source perfect for your grow.

Modern LEDs have come a long way since their initial development and use in practical technology. The advantages of LEDs include lower energy consumption than traditional HID and CMH lamps. Additional improvements include a improved durability, small size, and faster switching of the diodes. In fact, LED technology has improved so much that can even be used as in-home lighting.



Advantages of LEDs


Color: LED lighting will emit a specified color of light with no need for filters, and that means less to buy at start-up.

Slow failure: LEDs fail by dimmer over time versus the immediate failure of other lighting solutions.

Efficiency: LED lights produce more lumens per watt than incandescent lighting. LED efficiency isn't affected by the shape or size the way it is with florescent lights or tubes.

Warmup: LEDs warm up quickly, full brightness in about a microsecond.

Cycling: LEDs are perfect for applications requiring frequent on-off cycling and won't fail as quickly as other lighting types subjected to cycling.

Cool light: LEDs radiate little heat compared to other horticultural lighting types.

Dimming: LEDs can be dimmed by lowering the forward current or pulse width modulation.

Lifetime: Generally, LEDs have a long, useful life. They require less maintenance too.

Shock resistance: LEDs are solid-state components and durable. They aren't as fragile as other lighting types.
