20 years testing isn't due to the glass bulb it's due to the heads being quick response. You can get standard response heads with bulbs that will last another fifty years.
Check this head out: https://www.reliablesprinkler.com/sites/default/files/products/bulletins/013.pdf This is an SR bulb head that has it's 1/2" version listed to 250 psi instead of the standard 175. I see that as a nice value added feature for no extra cost, but that's just me.
