Perhaps I am confused about what we are talking about? That thing only puts
out 700 lumens or so, less than a 60 watt incandescent.
I assumed the question was about those 500 watt halogen "sticks" that put out
over 10 times as much light. Eg,

Sorry, I can't help with how long they last. I only have them in a some shop
lights that I almost never use.
Just a thought though: High power bare LED "pucks" are pretty cheap if you buy
them in bulk on flea-bay. For example, here is
10,000 lumens worth for $12.

Too soon to say how long it will last, but so far I've had good luck using JB
Weld to secure them to a heavy aluminum plate as a
heat sink. Of course then you'll need a suitable power supply, but the
Internet is full of designs. Here's one that is
transformerless (ie cheap) and I think should be fairly easily scaled for
higher current LEDs.
