how much heat do halogen bulbs emit?

[scientist123]

I have three solar panels of 250W and each panel is to be illuminated with 650W 7 bulbs total of 5Kw approx i.e 15Kw of power in total now how much would the heat be produced in room?
The room size is :13400m(L)*6777m(B)*5025(H).
consider non a/c room and let ambient temperature =30 deg C

Hi,

100%

(or does any energy leave the room? )

Agreed. If all the energy enters the room and none leaves it, all the power contributes to the heating.

It does beg the question of why would anyone want to artificially illuminate a solar panel though, it would seem to negate their purpose.

I presume scientist123 meaned to ask for the expectable room overtemperature.

If no venting is provided, we have to estimate the heat dissipation through the walls. I guess, the setup doesn't work without massive venting. Calculation is simple, air heat capacity is 1.3 kJ/(m³*K), when accepting 10 K overtemperature, you need 1.2 m³/s (respectively 4200 m³/h) venting.

But one has to concede that the OP requirement is....strange?

Why do you want to illuminate a solar panel with an artificial light source in the first place?

To make a solar simulator.

thanks,
It's found that around 100K lux is required to produce irradiance of 1000W/m^2 as per this link;
https://en.wikipedia.org/wiki/Lux
hence I wanted to know what lux is required to produce 800W/m^2, 600W/m^2 and so on...
