How many light strands can I connect end-to-end?
Underwriter's Laboratory (UL) recently updated the standard for seasonal holiday lighting using LEDs. The previous standard which was based on incandescent lighting wattage only allowed for the end-to-end connection of 3 sets. The new standard allows for the end-to-end connection of a total of 220 watts. Thus, the number of stings you can connect end-to-end depends on the total wattage of each string. All of our products indicate how many strings can be connected end-to-end in the product details.
