So the last portion of your question, first. I would say that the replacement of older LED is probably pretty nascent at this point in time. The board is quite pleased probably with what they have. So, when we think about the overall install base, we still think that the marketplace is $500 billion to $600 billion market, where outdoor is probably 10% or 11%, converted indoor is less than 5%. So, the solution sets that we are bringing into the market place, literally as we speak, whether it's nLight AIR, nLight ECLYPSE, whether it's our sub-metering capabilities, all of these things are new solutions that are directed towards primarily the huge install base. Where I see on some of these small projects, both new and renovation, we’ve sensed and we believe that people just took a break. I mean they were, for whatever reason, why this happens I don’t know. We think we saw it two years ago. We think we saw it four years ago during the political election process, where people just stopped, larger projects you can't do that, because you put in place a while ago. So, our expectation is that because of the size of the installed base, because of the solution set, because of the energy savings, which are significant; paybacks are significant and now that you add our IoT software platform on top of that, it's a very compelling value proposition in its totality. So we expect, over the longer term, marketplace to really continue to raise and absorb these types of solution sets. And others will have competing solution sets. And we want that. We want more and more people to be evangelizing proper solution sets. Unfortunately, right now, there are too many people out there that are saying they’re going to do things, and they really haven't. So, it creates a little bit of a noise out there. But in and of itself that’s not a problem over the longer term.
