Purely by chance I came across that same supplier's website yesterday while searching around. It is near impossible to get the 3 wire lights locally now let alone in single colour sets with wires that aren't clear. I would be very interested to know how you get on with this supplier. Do they make lights to suit a specific purpose e.g. with multiple channels or custom voltage? Do they arrange shipping for you? Is there a minimum order quantity?
Thanks for starting this thread about your order. What stage is it at? Have the lights arrived or have you only just placed the order?
