127V mine explosion-proof LED lighting, why 220V can also be used?
Because you are using (input) wide voltage products, such as 110-265V 85-265V, as long as your voltage anger is below 85V, you can use.
Since most LED lighting transformers are switching power supplies, wide voltage Wei Fan is used, preferably with a voltage divider resistor
LED can withstand a large range of load, mine light is originally good quality, not surprising.
