Not sure where you studied economics but you may want to go and ask for your money back.
Nearly every part in an HDS is a custom made part, either machined, molded, or put together at a pick and place. The more one has done at one time in quantity, the lower the price per unit. The difference between having 3 years of parts machined, anodized, vapor metal coated, electronics put together, emitters mounted etc. vs. 1 year is substantial. Had we ordered a years worth, you would have seen a nearly 50% increase in the cost of the light... then if things continue on the same route next year, you would see another increase next year, and the year after that. The reason for all the extra parts was to keep the costs down as much as possible and keep the cost of the light stable for the next few years.
Now, we could have left the price alone and started running HDS at a loss, but the only long term successful business I know of that has done that is the U.S. government... or an entity in financial bed with it.
I realize there will be people who will read this and because of **** poor reading comprehension skills, not understand and go off thinking the price of the light will increase 50% every year... I can't fix that... though someone should possible go back and slap their English teachers.
