First you need to decide how bright of a Qbeam light you need. This largely depends on two things : what you'll be using the light for and where you'll be using it for. When you consider what you'll be using it for, don't just think of what you might need it for right now. Instead, consider what uses you might have in the future as well. Your goal is to find a light that will meet the most needs possible, as that will provide the most value.
Second, you'll need to consider where you'll be using your Qbeam light. If you're looking for a spotlight to light up your flag or to dissuade possible intruders, you probably want the brightest light you can find. However, you need to consider the area in which you'll be using the light. If it will be in your yard an you have close neighbors, you don't want to end up being the most hated neighbor on the block due to your bright lights.
Once you've decided which type of Qbeam light you want, you'll need to decide who to buy it from. Your best bet is usually to look online. Online stores typically offer the lowest prices and the largest selection, which goes a long way towards ensuring you're not only getting exactly what you want, but getting a good value as well. Look for stores like www.outdoorlightingsource.com that specialize in this type of outdoor lighting, as they'll typically be the best resource.
You want to remember that just paying the least amount for your Qbeam doesn't always translate into the best value. If you buy a light that ends up being used or refurbished and it breaks down within a few weeks, you'll soon realize that the low price you paid wasn't a good value after all. You want to make sure that you're buying authentic brand new products. You should also consider the customer service of the company you choose and look for a company that is easy to get a hold of in a variety of ways.
A Qbeam is an excellent choice if you're looking for a high quality product. In addition to a high quality product though, you want to make sure that you're getting the most value by finding an online store with a competitive price. Once you know what you're looking for, you'll want to find a store that specializes in outdoor lighting and browse their inventory. Make sure you're buying products that are brand new and that come from a company who provides good customer service.
