Just purchased a LED light bulb with 13 diodes , how many watts is that equivalent to ?

Difficult to say - LEDs come in various packages, from 10 mW (0.01 W) to ~10 W per package.

However, if nothing else is written on the lamp's box, it's probably safe to assume that that bulb has standard LEDs with 50 mW (0.05 W) each, overloadable (with severe reductions in lifetime) to maybe 100 mW each - which would make your bulb have between 1/2 and 1 Watt. Which would be equivalent to an incandescent between 2..5 Watts.

The cheaper LED lamps with a large no. of LEDs are usually very low watts, maybe 1 or less.

there are higher wattages now, single LEDs of 3 and 5 watts and a few 3-LED lamps. If you want to buy an LED lamp that is more than 3 watts it will cost at least £10.

Impossible to say as LEDs come in different powers.

Also, do you mean actual power consumed or equivalent light output as an incandescent bulb of the particular wattage?

Are LEDs greater effectual than CFLs? LED bulbs are greater effectual than compact fluorescent (or CFLs), with maximum exerts agreeing that maximum LEDs final 10 circumstances longer than CFLs (and 60 circumstances longer than classic incandescent bulbs). The CFls would final from 6,000 15,000 hours of use on an identical time as the LEDs or mild emitting diodes lasts for approximately a hundred,000 hours. by utilising the way CFLs additionally incorporate mercury so its disposal could be dealt with with care. (power effectual good internet site) the situation with LEDs is they’re nonetheless significantly greater high priced than CFLs and nonetheless war with accomplishing the comparable equivalent output of CFLs in mild universal for lighting fixtures in residences (LED mild output is leading in

Probably 13 watts, producing 450 to 650 lumens, about equivalent to a 40 watt of incandescent bulb. It will last 50 times longer though

Also possible you got a more efficient version that kicks out a lot more lumens per watt

It doesn't work like that. There are different "values" of LED's. But the question is why do you ask?

The package should say, or Google the name and product #.

It should say on side of lamp
