A black wire bulb string that withstands heat is available. The string is ready with its plug. One bulb per meter, 48 meters with 48 bulbs. The light color is creamy, the best type of cool light for the eyes. The bulbs are shatterproof and energy-saving at 9 watts. Whoever buys it must install a tensioner for it to ensure it doesn't break because the string is long and will last a long time. And there is a 10m string with 10 bulbs (only one string available).
