Depending on the cost, this might become the lowest hanging fruit at some point in the near future

They don't seem to be expensive, although we do need focusing lens

lots of different focus types. parabolic lenses, wide flood, narrow spot .... lately I have been thinking a lens without a focal point is best. rather just catch the sideways light and push them straight down for a more even coverage than one with a hot center focal point. Suggest study of lenses designed for streetlamps.

Yeah I hope so. More funding more research and development. Only good things for us small fries. More sales means a savings for the end user eventually. As much as I hope to be a part of the real led boom I am more optimistic about people getting quality lights to use that are more user friendly than standard hps tech. I want all growers to be successful. I love to see a journal where a new grower has done their due diligence studied up and had a successful first run. I wish everyone had the passion that some of you guys have here.

binos and scopes use this on glass. It's called HELR coating......each proprietor calles it something different.

The coating and quality of glass makes the difference between the crap 200$ scopes you buy at Walmart vs the 4,000$ scopes that professionals use

So to get the best transmission you'd be paying for it big time.
