When sourcing Sharpy Lights (Beam Moving Heads), the most critical component is the lamp source, typically a 7R (230W) or 10R (280W) discharge lamp. You must verify the luminous flux and color temperature (usually 8000K) to ensure high brightness. Additionally, check the optical lens quality; a high-precision multi-layer coated glass lens is essential for a sharp, 0-4 degree beam angle without color fringing. Ensure the motor system supports 16-bit pan/tilt rotation for smooth, jitter-free movement.
