LED Grow Lights – Cost-Effective and Energy-Efficient Alternative for Gardening Lights

17 Sep

When a person asks about how to grow a garden indoors, a recommended solution is the utilization of LED grow lights. Grow lights, LED (light emitting diode) specifically, are electrically-charged and are designed to provide the electromagnectic spectrum needed by plants for photosynthesis.

Light-Emitting Diode Garden Lighting in Detail

The LED grow light can be used to provide the 4 chlorophyll absorption peaks: 2 red and 2 blue. It is said that 25%  blue is best for all-purpose plant growing whereas the 50 or 75% blue light is recommended for speeding up growth. The 100% red light is best if one wants to hasten fruiting. Many people have made their own LED grow light review and even NASA is recognizing the potential of this new light source.

LED growing lights are desirable from gardening needs. They are bright, have long lives and emit wavelengths specific for the plant needs. They are energy-efficient, do not need ballasts and are not as heat-producing as HID lamps. Because less heat is produced, the plants do not have to transpire as much and the watering frequency can be reduced. These lights can have 100,000 hour lives.

Examples – Garden Lights

One example of a good light emitting diode light is the Procyon 100. It is manufactured by Cree, a leading company in the LED industry. It can deliver 100-watt nominal power and consumes 125 watts. It does not require a ballast and can replace a 400-watt HID light. Its light can span 10 square feet and it can last 50,000 hours. The Lightblaze 400 can also replace a 400-watt HID lamp. Like the previous example, it also features 56 Cree Xlamp LEDs, with its own adjustable intensity dial and built-in power supply. Its lifespan is about 60,000 hours.


These lights are also available in different luminaires. The luminary system provides the power needed to produce a desired color. T8 lamps are generally 25 mm in diameter whereas T5 lamps are 12 mm in diameter. LEDs with T8 luminaires can have a brightness equal to or above a traditional 20-watt fluorescent lamp

How to Make your Own Light Emitting Diode Light

Cheap LED grow lights are present in the market but one can go even further and make a personal LED lighting system. DIY LED grow light ideas are now available particularly for hydroponic systems. Some companies offer light kits with instructions on how to handle hydroponic LED grow lights. For instance, a 12 volt kit is now in the market. This kit uses 256 5mm LEDs, uses 16 watts and has a 100,000 hour life. One only has to have a solder, a soldering iron and a basic knowledge of electronics in order to build this system.

These types of light systems are very efficient because they are specific for the wavelengths that plants need. One might wonder whether 1000 watt led grow lights would equal the performance of a 1000 watt HPS system. This is not so. In fact, there is no need for the former because just a 350-watt LED grow lighting system would already outperform a 1000-watt HPS particularly in terms of plant yield and in terms of expense minimization. Therefore, Light Emitting Diode systems are the best when one wants to achieve a truly fruitful garden.
