The  market for Hpa is an unknown in some repects, with the comencement of production  and the establishment of a secure quality supply will this allow users to ramp up the productions of products, I own no led light bulbs as they are expensive and still a novelty. sure got the odd battery light with one in it but as a common household product I have none.  I would expect this to start changing soon as more of these items become abailable and the price comes down. You can be sure that the manufacturers of the leds are probably increasing production capacity to be able to handlle the increased supply they have secured through NDA's with Orbite. JMO but this is how business works.
