Philips say those are designed for plastic lenses... the quartz envelope filters out the worst of the UV.
As for heat... that's pretty much identical to an ordinary QH 55/60W bulb. Since a fraction more energy is leaving the unit as useful light rather than heat, in theory the headlight should run fractionally cooler!
In short, they'll be fine.
