LED lighting seems to be the wave of the future – or the present if you consider how widespread the technology is even today. The standard Light-Emitting Diode, or LED, consists of a diode which produces light when activates by sufficient voltage. This causes dormant electrons in the electron hole to reform and produce light, where the color of the light is dependent on the semiconductor’s band gap. There’s plenty of technical information to read on the topic, but here you’ll be able to find reviews for several different LED light systems, including one designed for growing plants.
The Cree 9.5 watt bulb actually shows us how far LED technology has come since the late 1960s when it was first introduced to the public. This bulb, which uses only a fraction of the energy demanded by incandescent light bulbs, also produces nearly 800 lumens worth of light. Compared to a 60 watt incandescent bulb which produces only 540 lumens, a value which will decrease steadily as the filament gets closer to burning through, it’s clear which is the more energy efficient option. The only thing about the Cree 9.5 watt bulb is its cost – about $9.97 per bulb.
Considering the fact you can run that bulb for a year at a cost of about $1.14, many LED bulbs will pay for themselves over the life of the bulb. The new 3W Extreme LED system from Diamond Series LEDs comes in a wide variety of power levels, from 100w total all the way up to 800w. The 100w units can actually be daisy-chained together to create a single lighting element with an ever increasing amount of power behind it. They are excellent growing lights for indoor or outdoor use, but they do come with a hefty price tag. You might want to check here if you’re looking for cheaper LED grow lights.
The G7 Power Incline bulb looks pretty good from a consumer’s point of view. It comes with an amazing 10 year warranty which guards against all defects in manufacturing, which is admittedly a better warranty than most other bulb makers are offering. To top that off, the bulb produces omnidirectional light, which is to say it expels light in all directions when active, rather than just out of the top or in uneven points around the diameter of the bulb. This simple bulb which works indoors or outdoors and requires no additional ventilation also runs for less than $10 at most retailers.
Right now, these are three of the best LED light bulbs you can find on the market. While the second is a specialized system for growing plants and therefore far more expensive than the first or second bulb, it too represents top of the line technology with respects to its specific application. All of these bulbs are excellent when used for their intended purposes, and if you haven’t already, replacing any old and costly incandescent bulbs around your home with newer LED varieties is pretty much guaranteed to lower your monthly electricity bill. The initial cost can be scary for people used to getting bulbs for $2 though.
