U can google it actually.

But it's photosynthetically active radiation. Its another way to measure the amount of lights u need much like how ppl use watts as a measure. PAR is the amount of light ur corals need to photosynthesize and grow much like a plant.

The higher the value, the better. However terms like photosaturation and photoinhibition would pop up. Better for u to read it up.

Too many people spend money they haven't earned to buy things they don't want to impress people they don't like.

Cheap leds does not meet the required spectrum for maintaining lps. Look for higher end ones like ecoxotic PAR38 or maxspect series for beginners, its affordable and even cheaper second hand.

Quality lighting is important. Most people believe in the blues as it has better penetration through salt water. But at 2ft, most wavelengths will actually make it through, unless you tell me your tank is more than 100m deep. Two important ranges would be the blue as well as the red spectrum which are important to the zoox.

Zoas or mushroom corals longneck because they are trying to reach for more light.

In a simplified term, the led wattage is not enough, also Led needs optics to focus to allow the light to penetrate deeper. The "cheap led" normally does not include the optics.
