Frequently Asked Questions

Q: What voltage does the 650nm red laser dot module require?

A: The Elubor 650nm 5mW red laser dot module operates on a DC working voltage of 3V to 4.5V with a working current of less than 40mA. It is compatible with standard AA batteries or any regulated DC power supply within this range. Batteries are not included.

Q: Can this laser dot module be used for stage lighting or DJ effects?

A: Yes! The module is well-suited for professional stage and DJ lighting applications. Its 650nm visible red beam produces a sharp, bright dot that can be incorporated into custom lighting rigs, laser effect systems, and visual displays.

Q: What is the beam size of this red laser module at a distance?

A: The beam divergence of this module produces a dot diameter of approximately Φ10–15mm at a distance of 15 meters, making it practical for both short-range and medium-range targeting or display applications.

Q: Is the laser dot focusable or adjustable?

A: This particular model (650MD-5-0918) is a fixed-focus dot laser module — it is not adjustable or focusable. It emits a consistent red dot pattern suitable for alignment and visual effect applications as-is.

Q: How many modules come in the package?

A: This listing is available in quantities of 3 to 50 pieces per order, giving you the flexibility to stock up for prototyping, production, or project use at a great value.
