The Cross pattern is set to 120 degrees by default, and the focus is manually adjustable so you can fine-tune the beam spread or sharpness for your specific application.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I power this laser module from a laptop or power bank?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The module is USB powered and operates at 5 V \/ 120 mA, meaning it works with any standard USB port — including laptops, USB wall adapters, and USB power banks. No special power supply is required.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this laser module suitable for stage and DJ lighting setups?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. The module is designed for professional stage and DJ environments, delivering a vivid 638 nm orange-red beam at 100 mW. Its compact 12×35 mm body makes it easy to integrate into existing rigs, and the switchable beam shapes add flexibility for dynamic lighting effects.\u003c\/p\u003e\n\u003ch4\u003eQ: What safety precautions should I take when using this laser module?\u003c\/h4\u003e\n\u003cp\u003eA: Always avoid directing the beam toward eyes or reflective surfaces that could redirect it unexpectedly. Use appropriate laser safety eyewear when working in close proximity to the beam. Keep out of reach of children. Refer to your local laser safety regulations for compliance requirements.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What beam shapes does the 638nm laser diode module support?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The Elubor 638nm 100mW laser module supports three beam shapes — Dot, Line, and Cross.
