Natural light is best for plants during all growth phases, but I'll be growing indoors, It's a good idea to have a basic understanding of the light spectrum and how it affects plant growth, in order to choose the best lighting for my indoor gardening needs.

By Photosynthesis. Chlorophyll in the plant converts carbon dioxide into food using light energy. Light quality, quantity and duration. Quantity refers to light's intensity, while duration is the length of time the light is present. Quality of light refers to its wavelength, or color according to some scientists.

Sunlight includes all colors of light. Plants only absorb light in the red and blue wavelengths, so orange, yellow, green, indigo and violet are theoretically are unnecessary.

if you want to grow chili peppers then you want lots of light. Getting a crop to grow indoors is far different than just getting a plant to grow. Your only feasible option is high intensity discharge lights.

Wikipedia describes them as

HID lamps have made indoor gardening practical, particularly for plants that require high levels of direct sunlight in their natural habitat; HID lamps, specifically metal halide and high-pressure sodium, are a common light source for indoor gardens. They are also used to reproduce tropical intensity sunlight for indoor aquaria.

Any hydroponics shop will have them in stock. They run hot and use more electricity than fluorescents so a fan may be required.
