This set of 20 retro hook-able bulb festoon string lights are warm white in colour, with 5 LED’s per bulb, so 100 LED’s. Up to 5 sets of these lights can be connected together to make one large string and should then be long enough for anyone’s needs. Each bulb has an in-built hook at the top to attach it to ensure you can get the display exactly as you want it to look. For indoor or outdoor use.
