I just looked at some Christmas 2006 approved rope light. The difference is the actuall connection to the rope is a molded connector. It had a threaded end with male and female pins. These are 25' strings, packaged 2 in a box and I paid $6 for it. The only difference between this and the original product is you can't take the connectors off the rope. A very simple and safe answer to the "cutting" issue would be a glued on, permanent cap for the cut end. Perhaps the manufacturer would do that and seek the listing if the demand was there
ITO, compared to the regular store price, this guy isn't all that cheap. You can buy a 50' box, (2 strands of 25') with 2 power cords for 10-15 bucks. 150 feet is less than he charges with an extra power cord to boot.
Reading thru, seems that the mfg is hinting that it can be cut every 24" marked increment; but they also state that they don't condone, reccomend, etc., cutting. Something to the effect of 'cut at your own risk'. No cutting instructions supplied! 'Use common sense'; '40 year old design' etc.
Snip, seperate, insulate, seal ??
Last job I saw rope on, I had to tell the EC that the tag states 'do not coil excess'. John
