Various types of LED Grow lights
This category contains just the LED growlights no stands just the lights.
The choices regarding LED growlights is becoming greater and greater. Which is great news for the indoor gardener, but it can also get a bit confusing and making a decision can be difficult.
LEDs Power rating e.g. 1W vs 2W & 3W
In the world of LED Grow Lights, the most common LED chips are 1W and 3W diodes. The labelling of these diodes however, confuses most people as they expect the name of the product to match its power consumption. With LEDs however, this is not always the case. The wattage of a LED is determined by the current (amps) they are driven at, with 1W LEDs driven at 350mA, and 3W LEDs driven at 700mA. Despite the fact that 3W LEDs are driven at double the amperage of a 1W, and normally consume only 2W of actual power, LED manufacturers have labelled them a 3W. It is important to note that anything labelled a 3W LED, is by all intents and purposes a 2W LED. However
3W LEDs are best driven at 600mA, or about 1.6W per LED. The reason the LEDs are not driven at 700mA as they are rated, is that it reduces the efficiency, increases heat, and reduces lifespan. At 550-600mA the 3W LEDs test 5% more efficient in terms of lumens per watt than at 700mA, & run up to 15 degrees cooler, and last much longer.
Be careful however, of companies using 3W LEDs to trick you with their marketing.
Summary:-
A 2W is approx. 1.5 x as bright as a 1W (2W LEDs are best driven at 500mA)
A 3W is approx. 1.7 x as bright as a 1W. (as 1W is more likely 0.9W)
What we look for is value for money, reliability and choices with regard to different growing criteria. So if you look at the lights that we are offering there are basically 3 groups but as you will see some of them overlap.
The most common LED grow lights, eg the UFO series consists of 1, 2, 3 or 4watt LEDs, which have a standard internal lens of 120° i.e. wide-angle. The biggest advantage of these lights, is generally their price the ones we have chosen for this category also have the feature of being able to switch between a vegative stage and then bring in the remaining lights to boost intensity in the red spectrum for the fruiting stage.
A 2nd type of light are those that use lenses to focus the original 120° spread into a small beam therefore increasing the intensity of the light. The obvious advantage of these lights is that there is no wasted light going to the sides and the light that the plant's underneath receive has more energy i.e. higher intensity.
A 3rd type of light, which may or may not have additional lenses, is categorised by not having a fan and therefore having the power supply mounted remotely. The no noise operation and the lighter weight of this type of light, makes them extremely flexible, they also have a higher level of water resistance, so they are safer. These features make them extremely versatile when growing in your living area & small spaces.
