LED Grow Lights
We stock a great choice of only the best LED grow lights, offering incredible full spectrum light while producing drastically less heat in comparison to HPS lighting. Compact and lightweight, LED grow lights are now a true alternative to the traditional HPS grow lights. With no lamps to replace after each grow-cycle, LED grow lights are very low maintenance. Add to that the long lifespan (several years at least) and tailor-made light spectrums especially developed for optimum plant growth, these lights can really revolutionise your growing experience. Final crop quality is increased greatly because of the vastly improved spectrum of light that they produce. We offer only the best models available on the market, all the LED grow lighting that we stock have been extensively tested by ourselves, and each one represents the best that you can get at its price point.
The fantastic benefits of the best LED Grow Lights
Our range of hydroponics LED grow lights keeps getting bigger and better. We hand-pick only the very best to offer to you such as products from top manufacturers like Gavita, Maxibright, Grow Northern and Sanlight. We stock models which can replace traditional 400w, 600w, and 1000w HPS (High Pressure Sodium) or Metal Halide (MH) grow light systems. We also stock lower power models for propagation and the early vegetative stages. The Photon even offers a modular system which can be added to and expanded to whatever you need.
LED grow lights offer:
- Greater efficiency than HPS - they give more light per watt of electricity
- Most of them emit a full spectrum of PAR light - ideal for plant health, plant growth, final yields and harvest quality
- The light is focused straight down onto your plants rather than needing a reflector
- They run much cooler than other types of grow light with no infrared - greatly reduced heat problems, even in Summer
- They last for many years
- No bulbs to change out regularly
- They barely deteriorate over their long lifespan - up to 11 years or, sometimes, even longer
- They reduce running costs
- Contain no mercury or other environmentally unfriendly substances
- Completely recyclable
Originally, NASA came up with the concept of LED Grow Lights so that astronauts could grow their own food in space. Back then, the component LEDs (Light Emitting Diodes) were not very efficient and it has taken many years of development to reach the stage where, watt for watt, they not only match the results of HPS Grow Lights they actually exceed them. Because the higher quality models produce full spectrum light (including white), your plants will be happier and healthier, producing even better-quality crops! They are absolutely the future of growing. We stock models to suit every budget and with free next day shipping available.
LED grow lights are nothing like they used to be. They have so many advantages it is no wonder that growers everywhere are switching over to them. HPS used to be the standard grow light of choice because it offered the best yield per watt of electricity used. These days, the huge advances that have been made in LED technology by companies such as Cree and Osram, and the introduction of COB (Chip On Board) components means that they produce a lot more light for a given amount of electricity than they did even a few years ago. The net effect is that watt for watt, LED grow lights can beat the yields produced by a similar power HPS, all while producing far less heat. Even the top double-ended HPS models can't compete!
Efficiency - less heat and power consumption
The electrical power that is used by an LED is converted into a mixture of light and heat. If an LED produces more light for a given amount of electrical power, then it must also produce less heat. Watt for watt, LED grow lights produce much less heat than other types of grow light. The amount of PAR light they produce is measured in µmols / Joule. Some manufacturers state only the efficiency of the LED components themselves. LED grow light fixtures also contain a driver unit to change mains AC electricity into a few volts DC which LEDs run on. The drive units are never 100% efficient, so the efficiency of a fixture will always be lower than that of the LEDs themselves. When comparing LED grow lights, be careful check whether manufacturers are quoting the efficiency of just the LED components, or the efficiency of the whole unit. They do not produce lots of infrared light like HPS lights do. Infrared light is a type of radiation that heats up the object it lands on, but without heating up the air in-between. All in all, they help to avoid a lot of temperature problems that causes difficulties growing in the summer months. A great side-effect is that the risk of a fire in your grow room, which usually has disastrous and life-changing results, is reduced. Many models have the facility to have the power daisy-chained to multiple units.
Another great benefit of LED grow lights is their lifespan - usually 5 years at least, and many up to 11 years! That means no more changing out lamps on a regular basis. That can save lots of money and hassle over 5-10 years. Also, a high quality model uses less power so you'll be saving money on the electricity bill too!
The spectrum produced by an HPS is very much concentrated just in the orange & red part of the light spectrum. While that is perfectly ok for producing yields, we know that plants much prefer a full spectrum of light which includes blue, cyan, green and yellow as well. There is a myth that plants do not use green light. Although the cells on the top of leaves do reflect green to some extent, green light actually penetrates deeper into the canopy, and helps the plant to produce certain compounds. By growing plants using full spectrum LED grow lights, plants are healthier and have a better structure (stay shorter and bushier). On top of that, the inclusion of blue light in the spectrum means that the final crop quality is vastly superior. Full spectrum LEDs can be used right the way through a grow from start to finish meaning you don't have to change bulbs or grow lights when switching from cutting/seedling to the veg phase or to the flowering/fruiting stage. The full spectrum with plenty of blue encourages more resin, essential oil, terpene and flavonoid production. Putting a high quality LED grow light in your grow tent could be the best investment that you will ever make for your garden.
How to compare different models of LED grow light
We only stock the very best LED grow lights, so whichever one you choose, it will be fantastic value for money. There are 3 main ways of comparing them:
- The amount of light that they produce for the amount of electrical energy that they use. This is measured in µmols / Joule and is sometimes called the efficiency. (A Joule is basically 1 Watt per second).
- The light spectrum they put out
- The evenness of the light footprint over the area that they have been designed to cover
Tips for Growing under LED Grow Lights
LEDs produce less heat than the equivalent wattage HPS. This means that plants transpire less. As a result, they lose less water through their leaves and there is less water loss from the grow medium. You will probably find that you will have to water less frequently. Also, many growers recommend that you reduce nutrient strength by anything up to 30%. Play it by eye. being cautious to begin with. When you switch over to growing under LED grow lights, start off by reducing the nutrient strength by about 25% and increase it if you see any signs of deficiencies. On the other hand, if you see signs of nutrient burn, reduce the nutrient strength by a little bit more. Read your plants and react accordingly and you should be fine!
