Question:

Which is more energy saving by using 24V500W transformer lighting and 220V500W lighting?

Which is more energy saving by using 24V500W transformer lighting and 220V500W lighting?

Answer:

See whether the lamp power saving, can not see whether it has a transformer, but to see the light efficiency of the lamp, that is, the ratio of light flux to power!Popular speaking, that is, spend the same electricity to see who sends more light!So, when comparing, ask what the light is, then judge again!The luminous efficiency unit is LM/W

If the transformer is not calculated, the loss is the same. If the calculation is the latter, save electricity.

220V500W more power saving:Reasons: 1, high voltage, small current, line loss is small; 2, reduce the transformer and other intermediate links, each link has a loss.
