The electric field of the unpolarized light moves in all directions and undergoes phase changes over the coherence time of the two light waves. At any particular wavelength, a partially polarized light can be described as a mixture of polarized and unpolarized light.

Therefore, the resultant wave consists of a number of waves that originate at random times from atoms arranged relative to each other. The amplitudes of vibrations of these waves are equal.

On resolving each of these polarization directions into components along with directions that are mutually perpendicular to each other, unpolarized light can be considered as two perpendicular plane-polarized beams with equal magnitude. Thus, when the unpolarized light is transmitted through a polarizer, polarized light can be obtained.

The primary differences between spotlights and floodlights are their beam spread (the area of light coverage) and their intended uses.

Firstly, when using bulbs with the same wattage and beam angle, the lighting effects produced by different spotlights are the same.Here are the main differences between them:1. Size: The smallest ones are 2103 and 2104, followed by 2101, and the largest ones are 2102, 2106, 2105, and 2108.2. Presence of anti-glare shield: 2102, 2103, 2106, and 2104 come with adjustable anti-glare shields, which effectively prevent glare.3. Different bulb types: 2101, 2102, 2105, 2106, and 2108 use MR16 bulbs, 2103 uses MR11 bulbs, and 2104 uses MR8 bulbs. The difference lies in the wattage and beam angle of these bulb types. MR16 bulbs have higher wattage and wider beam angle, making them suitable for a wider range of applications and more popular. MR8 and MR11 bulbs have lower wattage and narrower beam angle (the numbers 8, 11, and 16 refer to the diameter of the bulbs, and generally, the larger the diameter, the higher the wattage and beam angle).Consider the appearance of the spotlights as well and choose the one that you prefer for focused lighting.

Floodlights, on the other hand, provide a much broader beam of light, often between 40 to 120 degrees, casting a large pool of light. This makes them suitable for illuminating larger areas, such as driveways, yards, patios, or for security purposes to light up dark areas around a property.

Spotlights typically produce a narrow beam of light, usually no wider than 45 degrees. This tight, focused light beam is perfect for highlighting specific points of interest, such as architectural details, garden features like statues or trees, or artwork. Spotlights can also be used for task lighting in certain situations.

The polarization of a light wave is defined as a type of orientation of oscillations of the wave with respect to the direction of propagation of the wave.

Unpolarized light, in general, consists of polarized components in all directions perpendicular to the direction of propagation of the wave.

In unpolarized light, vibrations take place randomly in directions perpendicular to the direction of the wave. The electrons within the atoms of the light source undergo rapid transitions thereby producing a light wave for a short interval of time.

The transformer is not included in the light fixture, it is only included in some landscape lighting kits and you have to buy it separately.

Depends on the power of the transformer and the bulbs, while the electrical energy will inevitably lose 20% of the voltage during transmission.For example, if the transformer is 150W and each bulb is 5W, then 24 fixtures can be installed (150 x 80% ÷ 5).

Most of the common visible light sources including fluorescence and thermal radiation generate incoherent light waves. This radiation is produced independently by a large number of molecules or atoms with random polarization angles. Under this condition, the light is said to be unpolarized.

Keep in mind these are general estimates, and your specific needs may vary. You also want to consider the number of lights you're planning to use, their placement, and the color of the light (warmer or cooler light can affect how bright the light appears). As always, if you're unsure, consider consulting with a lighting professional.
