Radiant 2000 500W LED Grow Light

If you are a serious grower, whether a large commercial operation or a back-yard pro, you should check out this professional grade LED grow light the Radiant 2000. We are fans of American made products, and the US based company Agricultural Lighting Technologies fits the bill.

At first sight you can immediately tell that this is a well-designed light based on its outer enclosure, made of machined aluminum and moisture resistant components. In fact, it is rated IP55 so it’s suitable for wet and damp locations like inside a greenhouse. That tells you that it’s been developed for serious commercial grow facilities, but even the home grower can benefit from a lamp that is IP55 rated since it generally helps prevent rusting of components and increases the lamp’s longevity. This itself is important because the lamp isn’t cheap, selling for $1,499, so you might expect to get a long life out of your investment. It carries a 3 year warranty.
