I was thinking about it, but not sure how to do it yet without making it too messy. I want to actually look into the cheaper products and make a list for consumers that are after more affordable products. But because they are less efficient than standard technology, manufacturers almost never provide metric data to analyze them. They likely all have the data, as you have to work this out before actually putting designs to prototypes. But they know it will make their product look inferrior, because it is. So it requires i look at end user results and reviews to analyze them. Very difficult. I might create an entire article for light product recommendations.
