I find these kinds of questions interesting and often do back-of-the-envelop calcs to get a rough idea.Wondering how this will affect global helium supplies?
Reserves are generally estimated based on what is currently economical. If we actually started to run out of helium from the current gas fields, so the price went up, we'd just stop throwing so much of it away from the overwhelming majority of natural gas fields where the helium is not captured, because it would become profitable to capture it from more fields.So bulbs are not a big deal... Interestingly I just went and looked up what the total world helium reserves are - seems I completely misdeed a story last year that they found a new field in Africa adding another 6 or 7 years to the previously estimated 20 years worth remaining worldwide.
Seems there may be more of it than we thought.
I was thinking the same thing. Dang it, now something is better. Aesthetically better and more efficient.The cool thing is these bulbs make the old L-prize bulbs from 5 years ago look quaint now. In retrospect I should not have been so quick to jump on the bandwagon... had I waited I could have converted the entire house for the (subsidized!) price I spent on 3 of those just to play around
R style bulbs are often installed base up in ceiling cans. This concentrates the heat more around the electronics which can shorten their lifespan, probably from drying out the caps.My local Ace hardware has the occasional sale on LED bulbs, 4 for $1. 25 cents a piece. Reliability is ok so far, the R20 shape seems to be the least reliable.
I'd guess 90% of bulbs get installed base up. In whatever fixture. All of ours are, that I can think of, anyway.R style bulbs are often installed base up in ceiling cans. This concentrates the heat more around the electronics which can shorten their lifespan, probably from drying out the caps.
