Light energy is indeed considered to be a raw material. This is because it does not need to be altered by humans to be used.
photosynthesis
The product of the light reactions of photosynthesis is ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These molecules provide the energy necessary for the Calvin cycle (dark reactions) to produce glucose.
Photosynthesis involves the transformation of light energy into chemical energy.
The general equation for photosynthesis can be summarized as: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2. The product of photosynthesis is glucose (C6H12O6) and oxygen gas (O2).
Photosynthesis requires water, carbon dioxide, chlorophyll, and light. Glucose is an end product used as energy but it is not used during photosynthesis.

photosynthesis
The main energy-storing product of the light-dependent phase of photosynthesis is ATP (adenosine triphosphate) and NADPH. In the light-independent phase, the main energy-storing product is glucose.
The product of photosynthesis is Glucose and O2 is a byproduct.
Carbon dioxide + Water --light energy--> Glucose + Oxygen

Light energy is essential in photosynthesis.
Oxygen is released as a by product of photosynthesis.
The light from the sun provides the energy source that is required to initiate photosynthesis. Light is made up of photons which are "packets" of energy, and the energy from these packets excite the electrons on the plant's pigments. There are special proteins in the chloroplasts that utilize this energy and end up storing the energy in glucose (the main product of photosynthesis).
Light is not a reactant or a product in a chemical reaction because it does not undergo a chemical change. While light can provide the energy needed to drive certain reactions (such as photosynthesis), it is not consumed or produced in the process.
