Usb miners (which are made even simpler than mining lightbulbs) have been refined for years now, and they still are not profitable no matter the quantity. It's an industry of scale, even <1kW miners are going by the wayside, and as long as these standalone miners are in popular existence, light bulbs, pod and USB miners will not be sound financial investments, but rather niche products.
If a mining light bulb were able to turn a small profit, then a rack full of dedicated mining equipment could turn a considerably larger one, and keep cheap light bulbs where they belong. I can't think of any rational reason for a large company (let along individuals for any reason but curiousity/tinkering) to put ASICs in light bulbs. Unless the manufacturer was earning the mining revenue off their customer's electricity, which would simply be deception.
Well here's the deal...I don't think it was ever intended for large companies to use these light bulbs for mining according to the following quote anyway:
“We believe that the project’s focus should not be on making money from bitcoin mining, but on creating innovative solutions with main purpose to use this product for educational purposes and fun,” said BitFury CEO Valery Vavilov
So yeah basically an alternative to a USB miner for people with interest in learning about bitcoin technology, and giving them a touch of the bitcoin blockchain ecosystem. Obviously we (miners) know USB miners aren't money makers so these most likely won't be either, but still could be fun toys that teach more about bitcoin.
