Question

what do you mean by bulb rating
​

Answer 1

Answer:

When buying an incandescent bulb, the watts rating gives consumers a good indication of how bright a bulb is. The more watts, the brighter the bulb. That rule doesn't apply to LED bulbs, though. An LED that uses 60 watts is in no way comparable to an incandescent bulb that uses 60 watts.

Answer 2

Answer:

An electrical appliance such as electric bulb, geyser etc. is rated with power (P) and voltage (V) which is known as its power rating. For example: If an electric bulb is rated as 50W-220V, it means that when the bulb is lighted on a 220 V supply, it consumes 50 W electrical power.
