是否值得换成四个T8荧光灯+电子镇流器。好像既安静又省电。多谢。 | u****q 发帖数: 24345 | | v********e 发帖数: 1985 | 3 Not 养鸡的, but i think the first choice is replace the entire fixture with
4x T5. It will be shorter, same quality of light as T8, but more efficient.
If you don't want to spend the extra money, then go with 4x T8. | f****i 发帖数: 20252 | 4 随便
拿手摸摸镇流器热不热,热的话换了能省一点点电,不过估计也得好几年才会回本。
【在 u****q 的大作中提到】 : 养鸡的,你怎么看?
