How do I get the tightest spot pattern possible?
In general, when talking about lens optics the larger the optic the easier it is to collimate light into a

tighter pattern. Another consideration when trying to achieve a tight spot is the size of the LED die.

The smaller the size of the die the tighter the spot. For example, to get the tightest spot with our LEDs

you would want to use the Cree XP-E LED (smallest size die) and the 26mm plain tight lens (largest diameter optic).

The lens itself clips securely into the holder, but the holder does need to be externally adhered.
In the case of LED stars, optic holders have four legs that sit down into the grooves of the star board.
Lenses are often designed for use with specific LEDs. Check the manufacturer data for compatible LED options.
Some manufacturers pre-mount LEDs onto a board ready for the lens/reflector to sit over, saving you having to solder and line the LEDs up accurately.
