LEDs do make great solid state indicators for visual warning devices. Their low thermal properties and long life expectancy (roughly 50,000hrs) provide an excellent cost/benefit for these type of applications. The price point for these solid state lighting components are continuing to drop making them excellent replacements for some of the old incandescent light bulb indicators used in visual warning systems.
This is another great example of what can be done with all of the low-cost, wireless protocols that are available. This is an excellent replacement for power line carrier, and I'm sure there are many more designs where a small wireless network can be a solution.
I like the idea of smart LEDs, especially being able to get some warning about when it is time to change the bulb. I will have to check this got a couple of design ideas that would benefit from this product.
Wow. This is really great news. I've seen lots of plans for "smart" or "intelligent" lighting networks in the lab. It is great to see this developed into a product. The potential for energy conservation, illumination customization and mesh networks is really quite inspiring.
