Kaymar light replacement

Hi All

My almost never used LED Kaymar light has failed. Replaced it a few years back, think I've turned it on once.
Anyway, I won't be sourcing another one through them. Can anyone offer a suggestion of a product they have used? Needs to have a very strong mounting bracket. Will mount on top of the Kaymar pole, so will just have the 1 central mount as shown in photo. Don't wish to buy one only to pull up after the first few hundred kays of corrugations to find it swinging by the cable.
I know there are heaps around, but ordering online is a bit fraught as I won't have any idea of the strength of the bracket until it arrives.

Thanks

Lyndon
