LED Grow Lights in the UK have taken a leap! We’ve finally found one we’re happy to sell. Need help choosing an LED grow light? Here are some common questions (and their answers)!
Do LED Grow Lights Work?
It depends on what LEDs you have and how you’re using them. LED grow lights work really well if your output per Watt is high, and your coverage area is right.
The Telos 0008 LED has a high output of 1.9 μmol per Watt. In the right size area, it’s a truly awesome light. Just remember it’s a 240W light. You won’t get the same yield from 240W light as you will from a 600W HPS in the same area.
What warranty do you offer?
The Telos 0008 has a 3 year manufacturer’s warranty, but you can expect it to run at 90% efficiency for 85,000 hours. That’s almost 10 years!
What LED Grow Lights do you sell?
At the moment we only sell one LED growing light – the GNTelos 0008 (made by Grownorthern). It’s the first UK LED grow light that lives up to our expectations and is a good price.
How many LED lights do I need?
One Grownorthern Telos 0008 emits 450μmol/s. This is fine over roughly 1 square meter for propagation and vegetative growth.
For fruiting and flowering, you’ll need 800-1000μmol/s per square metre, so two of these LED light systems would be the best option.
What’s the difference between LED and HPS Lights?
HPS lights are made up of a ballast, lamp and reflector. They tend to have a much higher output, with the most popular being 600W HPS. LED lights use LED emitters and a driver to power them, often all assembled in a single fixture.
Can you use LED lights for cuttings?
Yes, they are great for propagation. Just make sure they’re correctly positioned above the cuttings to deliver a low level of light. Around 100cm will be ok.
Can you use LED lights for vegetative growth?
LEDs can be a great choice for vegetative grow rooms. They have a good broad spectrum suitable for both vegetative and flowering growth.
WiIl I get good yields from LED grow lights?
Yes. The technology is now here to enable growers to get yields as good as HPS using LEDs. As long as you get your wattage and hanging heights right.
Are LED lights cheaper to run?
LED grow lights in hydroponics are great if you’re looking to keep running cost down. They’re as efficient (output per Watt) as the best HPS light systems and are available at a lower wattage.
