LED Grow Light Comparison
Performing an LED grow light comparison is essential if you want to get the most out of your buds.
With so many LEDs to choose from, It’s important to know what to look for in a good LED grow light.
In this article, I’ll show you exactly what to look for, while also comparing some of the most most popular LED grow lights on the market.
Why Choose LED Grow Lights?
LED grow lights have taken the cannabis growing community by storm over the last few years.
And for good reason!
Here’s why you should be using LED over tractional types of grow light such as HPS:
- Bigger yields – An LED grow light will give you up to a full gram more per watt than an equivalent HPS, using less electricity.
- Lower Heat – Controlling the temperature of your grow room is costly. Compared to HPS grow lights, LED’s run much cooler. This means you don’t have to purchase cooling systems to reduce the heat of your grow room. There’s also a reduced fire risk.
- Energy Savings – LED grow lights use up to 50% less energy than HPS grow lights, meaning lower energy bills.
- Full Spectrum – LED’s are engineered to provide the exact spectrum of light that your plants need at every stage of their growth.
- Lifespan – the average HPS light will last 10,000 hours. An LED grow light will last 30,000 – 50,000 hours.
- Better for the environment – Unlike HPS lights, no toxic metals are used in LED grow lights.
- Easy to use – LEDs are very easy to setup compared to HPS grow lights, you just need to plug them in and you’re off.
How To Compare LED Grow Lights
Ok, now that we know why LED grow lights are a great choice for your plants.
But what should you actually look for in a good LED grow light?
Here are the most important things to look out for when comparing LED grow lights.
- High quality LED chips – Avoid LEDs that use cheap non brand chips with less than 3W’s of power.
- High PAR Output – PAR is the measurement of the usable light that your plants are getting from your fixture. It’s the most important value to consider when choosing a grow light if you want to get a big, potent yield. You need 200-400 umols of PAR for the veg stage and 700-900 umols for the flowering stage.
- Balanced, Full Spectrum – Most new LED grow lights come with a full spectrum these days, but you still need to check that there is a healthy balance between red and blue lights to ensure your plants are getting enough blue light when vegging and red light when flowering.
- IR wavelengths – IR wavelengths have been shown to increase yields and potency. Lights with these wavelengths are a big plus.
- Daisy Chaining Functionality – Optional but very handy if you plan on using more than two lights. This functionality allows you to connect lights together so that you require only one socket.
- Veg & Bloom Switch – Many LED’s come with two switches to optimise the light intensity for the veg and bloom stage. An optional feature but it can save you energy costs and ensure you’re plants are getting just the perfect amount of light.
- Good Warranty – Your grow light should have at least a 2-3 year warranty with good customer feedback.
ACTUAL WATTS: It’s also very important to understand what actual watts are when comparing LED grow lights.
Actual watts are what you should be using to compare the power of different grow lights.
Actual watts are what an LED light actually draws from the wall socket, and can be found by looking for information about how much electricity the light consumes.
Most grow light manufacturers use the total number of LED chips in their title as it looks more impressive. But this is misleading, as the true power of the light is nowhere near this value. For example, a light consisting of 100 3w LED chips might be called a 300w grow light, when the actual power draw is only 160w (actual watts ).
Always use actual watts to compare the power of different led grow lights.
