Spare optics for your Delta Flashlight
Tune your beam profile to your liking!
These are standard 20mm Carclo optics that work with a range on Nichia 219/319 and Cree XPG LEDs.
Please note: in order to fit the optic in a Delta light you need to use a sharp kinfe and trim off the small "runner" that is an artifact of the injection molding process (see photo #2). It is only important that this runner not stick out beyond the outside diameter of the optic. This is to prevent it from getting jammed inside the pill.
Available in 3 flavors:
It's easy to replace the optic in your Delta if you want to try out different beam patterns. Most people choose the spot optic for longer range. I personally use the wide optic to give me broad and even illumination for indoor and outdoor use at close range. Flashlight nerds sometimes refer to this as a "wall of light." If you can't choose...medium is a good option ;)
