Yuba heating is as long as the place where the light shines is warm, which has little to do with the size of the room, but mainly depends on the skin temperature of the Yuba. Yuba has 2, 3, and 4 bulbs. Generally, rooms with heating choose 2 or 3 bulbs, and rooms without heating choose 4 bulbs.
Standard Yuba bulbs are 275 watts, but low-quality bulbs heat up slowly and cannot reach the temperature specified by 275 watts. When choosing the Yuba, consumers can stand 1 meter away from the Yuba, turn on the Yuba, and feel the heating speed and temperature of the Yuba. The heating speed and the high temperature are relatively better.
