Well… The fundamental problem of the burning wire is the fact that only the top fraction of the power it needs can be converted to Light. All the rest is heat.
When that heat is dissipated through the bulb into Baby Chickens or Chocolate Cupcakes, it gets wasted.
What these guys have done, essentially, is worked out a way to keep that heat on the filament, without (much) loss, meaning it adds to the power needed to make (much more) light; and less heat gets out.
Meaning, for once, “It’s Cool”, will apply!!
All this and 100 CRI? Who don’t love that?
Edit: OH, and because it’s still (I think) a Resistive load, we won’t need funky drivers unless we just want them. Be still, my heart!
I have heard the new Nichia 319 series will START at 105 CRI and have a vF of 1.01V! In the mean time, I still miss sub dollar incandescent 100W bulbs….
Yep- some like it hot and who are we to take away their happiness? Incans hold a definite advantage inside during the wintertime but that seems to have been overlooked by the nutjobs who just want them to go away completely. Perhaps they just don’t like doing seasonal “emitter swaps”
There’s not really much need to swap where I live (Canada). By the time you no longer want the heat from incandescents, the days are already so long that very little artificial light is needed.
The article is vague. Hopefully MIT has improved on the infrared recycling technologies that already exist on the market, as seen in GE H7680 HIR bulbs and Osram 64447 IRC bulbs, etc.
True, but have you ever seen any 100w LED bulbs in a store? The highest I recall are somewhere around 13 watts, usually less. Can you even buy 100w A19 LED bulbs anywhere? That would be one helluva bright bulb! (And probably fry itself in no time.)
Just buy a halogen IR bulb, you can get them in many wattages from 25-500W. The incandescent was used because it happened to be available, but there are many ways to skin a cat, you can buy USB warmers, you can get space heaters in different wattages, you can use insulation as mentioned and so forth.
I personally would not have listened to my corporate overlords and banned the incandescent, i would have put a $5 tax on each bulb, and used that money for research and development of future technologies and other energy conservation programs.
Thats exactly what i was referring to. I used one when i lived in college to keep Bort warm at night.
Since they are on clearance there is obviously no cold chicken epidemic stoking demand.
