Make an Informed Choice
Now that we've shown that you can't trust advertising claims, why should you trust us and how can you make an informed choice? The answer to the first question is that all of our tests were conducted under identical conditions with the same test equipment. All the lights tested are typical examples. The Alpenglow lights were picked at random from stock, and the conventional fluorescent lights are random samples of those most widely sold by marine dealers. But don't take our word for it. We encourage you to buy only from sources that allow you to try the lights and return them if you aren't satisfied. Get several lights (including Alpenglow, of course) and make your own comparisons. You can easily make actual tests if you like. An expensive lux meter isn't necessary for approximate tests. All you need is an incident reading photographic light meter; however, visual comparisons are generally satisfactory. Fluorescent lights (and particularly Alpenglow lights) need about a minute to warm up to full brightness, so be sure to warm up all fluorescents before making comparisons. Also, be sure to compare brightness to the sides as well as straight below the lights.
