Agree... I find 240 watt 30 degree spread in a single row perfectly adequate at night up to about 90 KPH give or take.

Any faster is 'overdriving the lights' and I use my HID spots for 100 KPH or more but hate the warm up time so I intend to swap to LED soonish
A pair of 150W 9 inch round in 30 deg maybe on the cards...
