Without specific information, many of these questions become a "wild goose chase".
There is no indication of what OP's daughter is shooting- a product can be anything from tiny earrings to a truck! Tabletop-type product shoots can be just about anything that fits on a table.
The SUN is the one and only source of natural light on Earth but it can be direct, difussed, cloudy hazy overcast. Waht aspect of sunlight is required and what is it being lighted?
In a product shoot, in a studio-like indoor environment, "sunlight" can be simulated with anything from an optical or Fresnel spotlight to a giant softbox- depending on the effect that is required and the level of concentration or diffusion desired. So, the first part of the solution is to determine the quality of the light- hard, medium, soft, or very soft. Once that is determined the color temperature is not an issue because a white balance can be established for most conventional light sources- tungsten, quartz, LED, strobe, etc! A warm (sunset/sunrise) effect can be obtained by adjusting the white balance.
As for budget. Nowadas. withte popularity of strobe and LED, old-fashioned spotlights are being sold at reasonable prices on the used market. I found a few at cinematography equipment dealers being sold off from their rental inventory. These use 250-watt or 500-watt tungsten lamps with a color temperature of 3200K or 3400K which are easily white-balanced. The one in the attached image is a Bardwell & McAlister 500W Frenel and can be adjusted for various d levels of beam concentration or spread. Great for simulating direct sunlight. There are similar models with 500-watt and 1,00watt Quartz-Halogen lamps of the same color temperatures. I have an old Color-Tran model that works well. brand to look for is Mole-Richardson. Oldies but Goodies!
For a more diffused/ cloudy/overcast.hazy look, a strobe of continuous ligh sourcee in a big softbox is very popular among product shooters.
It's difficult for me to make a specific recommendation if I don't know what kinds of products are being photographed. Also...the light source is only one factor- you need to know how to place the lights to create dimensionality, render texture and address a wide variety of surfaces. If you are gonna try to shoot a highly polished "chrome-plated" product with a direct spotlight. you're gonna have quite a challenge on your hands!

Fresnel Spotlight

Strobes with Fresnel heads and snoots or diffusion material.
