Thorn's LU series were great weatherproof fittings. Most had 'Vivatronic' hard wired electronic starters with a switchstart version too. Polycarbonate diffusers and tamperproof toggles optional. If you see a twin version with a single lamp, it will have the integrated emergency battery pack and module.

Nice to see still in box but it won't be so invincible when the HF blows!

Thanks Kev! Should it ever get used and fail, I'd convert it to vivatronic start....
