For those of you who want the highest amount of light you can get in an easy retrofit, this might be the ultimate solution for you. This is a simple way to retrofit any type of high bay commercial light fixture where you want to do a simple bypass of the existing ballast and screw these in. Because of the way it's made, you're going to get light directionally down not in every direction and therefore wasting light. It's pointed in a downward direction which is where everybody really wants the light in any kind of facility or warehouse. This one will replace up to a 400 watt metal halide bulb and that means it will probably be most often used in a storage warehouse or general work facility. It has a frosted lens so that you're not going to get the glare of these points of light, just a smooth even light that will go throughout the space. It does come with a five-year warranty and so you're protected from any kind of early failure, but you should expect many years of reliable service and great light output. All you have to do is bypass the existing ballast to the voltage that you have coming into the commercial light fixture. The 5000K light color is perfect for most types of industrial facilities because it is a very white light and people can read well by it and people can see more easily things that are stored on racks. This one only draws 80 watts so you're going to have a fast payback and then you'll enjoy better lighting as a result as well.
