Are there any torches that have the same intensity as sunlight?

Electricity is just a power source. Light differs only in spectral composition, intensity, and polarization. Only a detailed spectral analysis would let you distinguish sunlight from spectrally-balanced light from other sources.
Both the spectral composition and the intensity of a torch depend on what's being burned. If you're burning phosphorous or magnesium, you could easily generate light more intense than sunlight.

It would be pretty hard to generate that intensity... and as for a torch... no chance. Plus sunlight has UV light etc aswell.
You can get pretty powerufl torches though, going into millions of watts. A watt is the light of one candle if im correct...

"electric" light is the combination spectrum of the filament and any gas that may be inside the glass envelope.
Sunlight is the spectrum of Helium, Hydrogen and other elements that are in the Sun's troposphere (flaming surface).
Spectrum is a mixture of different "colours" that are specific to each element when it is heated to a very high temperature (a bit like an elements fingerprint).

electric light is just energy released as light from the flow of resisted current in filament bulbs; and i don't know what in fluorescent ones
sunlight is part of the electromagnetic radiation coming from the sun which includes: UV, infrared, and i think radio and/or micro waves

I think the thing here is distance and temperature the sun is 8 million miles away and is at 6000 deg C...

sunlight is fusion
