They are the CRASH model from the EGLO lighting company.
It was literally used for a week. The cable was not altered nor cut, therefore you may use the length you require.
I am selling it for $30 for the single unit which is like NEW in its original box. It is worth $70 new.
Price reduced for a quick sale.
