"Back in my day, Sonny, we had light bulbs, vacuum packed glass globes that had a filament in them, You put power into it, and the filament put out light."
"I thought they were using transistors instead of vacuum tubes when you were a kid, grandpa", the young man asked, turning his inquisitively,
""No, Sonny, not for electronics, for light. None of these solid state glow thingies, Real Light, from a glowing filament."
""You mean like in a television picture tube? I have seen pictures of those at the museum."
Grandpa shook his head,knowing that it was a lost cause. "Kids nowadays, they have it too easy", he thought as he flipped through channel 987, looking for old reruns of Star Trek. "Just too easy."
The incandescent light bulb may indeed soon be a relic of the past, along with vacuum tubes and television picture tubes. Helping with its well-deserved demise is Planilum Light Emitting Glass.
Planilum bulbs consist of 4 layers of special glass, a rare gas and serigraphed phosphors. But they are not just pretty, they are efficient. One of these bulbs will last for about 50,000 hours, or about the same as 34 typical light duty light bulbs. In other words, you could expect it to last about 20 years.
The bulbs do not get hot to the touch, but rather stay close to the same temperature as the human body with a soft, warm glow. I can imagine how well these bulbs would lend themselves to uses in unique shapes that is not practical with hot, relatively short lasting sources of light. While Planilum Light Emitting Glass bulbs are not available yet, expect to see them in the not so distant future.
