Well, I give you some broad parameters, but I don't want to get into specifics in order not to tipoff my competitors as to what we're doing. As you know, there are a number of companies that are focused on smart lighting and IoT, and we see it as a major growth opportunity. We have an architecture that we believe is highly differentiated, and it's basically focused on using sensors, controls and wireless connectivity to adapt lighting and the quality of lights to the activities of people within buildings and reduce energy consumption. As you know, LED lighting already enables 150% reduction in energy consumption over conventional lighting, and by using some of these smart lighting techniques, detecting ambient light and adjusting the intensity, you can reduce energy consumption by another factor of 50%. So there's a very significant energy savings. But in addition to that, you have the opportunity to really tune lighting to the activities of people in buildings and enhance their comfort, their health, their well-being and their productivity. One example would be automatically tuning the color temperature, the correlated color temperature of lighting in buildings, to adapt to circadian rhythms, for example. This is something that's of great interest to a number of our healthcare clients. So these are just some of the directions in which we're going. Again, they're not entirely unique to us, but what is unique to us is the platform approach that we've taken to address some of these opportunities. And I don't want to get into more detail there in order not to tip our hand. So you'll have to be patient until LIGHTFAIR 2019, which is in May 2019, and our plan is to show our first product at that show. And then finally I'll just to finish up by saying that our plan remains to introduce, on average, one new-product family per quarter throughout 2019, and it might be more than that, it might be less. I actually said we would introduce two new products in 2018, and we beat that. We introduced 3 or 4. So my hope is that we'll beat the average of one per quarter in 2019, but that's what we've got in the plan right now.
