Norman we have not had any problems with LED Helios heads turning either on high poles. We did have a problem in the past with the old Siemens head coming off at normal height at specific sites where the topography of buildings seemed to increase the effects of the wind.

To my knowledge, we have never had a problem with them - apart from RTA's. They are obviously susceptible to the common problem of installers not always placing the locking split pins in the runners but as we always make a point of checking this, that is not a problem in Sefton. I note also that we have had less problems with the new Siemens Helios heads turning in the wind.
