Sorry people, my PC down, will provide links and reply PM tomorrow. I bought the connectors eventually, they are used to connect the 1m and 1.5m tracks. All my tracklights are warm light, sorry for the variance in photo, stupid phones's camera autobalance. Refer to my latest posts, the lights are in correct colours... In terms of inter switching, yes! The tracklights can be easily slided out of the tracks....
