LED has many advantages, especially in the world of horticulture since it consumes very little but is also very effective for our plants! But do you know the different types of LEDs that exist on the market? Each kind of LED will determine the lighting angle and the light output you want to give to your plants. Here is a brief summary of each of them.
1 - The LED Dip, old fashioned
The LED Dip is the oldest LED since it has been used for almost 40 years in our electrical and electronic devices. This LED is obviously less advanced than today's LEDs, it was mainly used to inform the user of the proper operation of the device. With a low yield but very inexpensive, it had a very small lighting angle (about 30 °). Unfortunately, with the poor performance of this first LED DIP, many people have kept a bad opinion of LED in general. Yet you will see later that some LEDs can be extremely powerful and effective ...
2 - SMD LED, the most used in the world
The Surface Mounting Device (SMD) LED is the most used LED in the world. It is also used frequently by indoor growers who wish to optimize the growth and flowering of their plants. Small and flat, it is welded to the surface of the electronic circuits. Since it produces almost no heat and still consumes very little, the SMD LED can exceed 80 lumens / watt (and LED) against 30 or 50 lumens for the LED DIP. Its lighting angle is also higher than that of the DIP (about 140 ° max).
This type of lighting therefore offers excellent value for money to all those who want to grow indoors. Especially since it is possible for manufacturers to create different colors for each LED.
For your information, you might see this kind of references: LED SMD5050, it simply means that the LED is SMD and its size is 5mm x 5mm.
Here is an example of LED horticultural lighting that uses this technology: BloomLED Brand SpectraLINE Bars
3 - The High-Power LED, a higher efficiency
The High-Power LED offers a high efficiency, ideal in the world of indoor growing, to illuminate plants growing or flowering. The High Power LED is simply an SMD LED that has been pushed to its maximum capacity, and to which we have added a lens. Focusing more light than the SMD LED, it offers superior light output and lumens.
On average, this LED offers a lighting angle of about 45 °, which adapts perfectly to the lighting of plants that need a bright and powerful light, seems to that of the sun. High Power LEDs have a little more heat than SMDs, but since they are more powerful, it's not surprising.
Here are some examples of lighting that uses this kind of LEDs: The SpectraBULB X30 LED Horticultural Bulb or the SpectraPANEL X160 Panel which also has a COB LED (see below)
4 - The COB LED, the most powerful on the market
The COB LED is used on various LED horticultural panels since it is ultra-powerful! It is composed of several bright chips (SMD type) which together form a single big LED.
Stable, powerful, durable, this type of LED is the ultimate in the world of LED. It is used in different horticultural bulbs, panels or spots.
A COB LED easily produces more than 100 lumens / watt. It resists voltage variations and has an 80 ° mid-angle illumination that makes it an ideal LED for home use.
This LED produces a little more heat than the LED SMD anyway. But some modules or LED panels with this technology are also equipped with passive cooling.
Here is an example of a bulb using this type of LED: Cannaled 200 or the bulb SpectraBULB X20 of the brand GreenVisuaLED
5 - The COB Filament LED, the latest
The COB Filament LED is the latest in the market. Coming from COB technology (several chips to form a single LED), it is in the form of a filament. This filament thus has several LEDs that compose it, as well as a layer of silicon to create a more homogeneous and constant light along the filament.
The advantages are the same as the COB LED, but are different because it offers an intermediate lighting angle of 360 ° (only LED has this feature).
This one may be just more fragile.
