I don't understand how this company can make money. So far none of their products are proprietary. So what does that leave them contributing to their business model besides their name, which is unknown? After paying manufacturing costs, packaging, shipping, travel expenses, promotional expenses, salaries, etc., what will they be left with? Any money that is to be made will go to Litetronics, the company manufacturing PureSpectrum's non-proprietary bulbs. This looks to me like a typical much to do about nothing penny stock. You will see that when they finally file their quarterly report, they will have nothing in the way of revenue. They will offer the excuse that it's the cost of starting a business but things are really picking up, but then the next quarterly report will also be dismal. They will offer more excuses and promises and it could go on for a couple more years. Buyer beware!
