An interesting price point. Some relevant comparisons are (at highway speed): - $8/hr in gas for compact gasoline cars (30 MPG, $4/gallon) - $2.25/hr in electricity for electric cars (0.25 kWh/mile, $0.15/kWh) - $12

Another way of setting a limit on radiation would be: 1/10 as much as an average coal plant per kWh. Current nuclear plants are already below this, because coal plants release a fair bit of radioactive material into the air, from trace

Other factors affect light output like frosted glass, which they didn’t want to forbid. Setting a target lifetime seems like a simple way of only regulating the lifetime-efficiency tradeoff while giving freedom on the others.

I agree. There are weasel-words throughout, starting with apologizing for "any harm". When you've been told what the harm was, don't apologize for "any harm" you might have caused. You should start an apology b
