[Bayonet-to-Screw Thread Conversion]: Changes the physical mounting method between bayonet-type and screw-type lamp holders. Allows screw-base bulbs to be used in bayonet holders, and vice versa. No modification to the internal wiring or terminal layout of the luminaire is required. [Tool-free Direct Installation]: Can be fitted into an existing lamp holder simply by inserting it by hand and rotating it through a certain angle. No screwdriver, wire strippers or soldering equipment is required. After removal, the original lamp holder remains unchanged and can still be used with its native type of bulb. [Heat Resistance Rating for Continuous Use]: The housing material maintains dimensional stability and insulation resistance under conditions of continuous heat generation from the bulb. During normal operation, the surface temperature rise is kept within a limited range, reducing the risk of surrounding plastic components softening or discolouring due to prolonged exposure to heat. [Mechanical Contact Retention Force]: Spring-loaded contact interfaces maintain contact pressure, compensating for minor thermal expansion and contraction. This reduces the likelihood of poor contact—which, in dimmable circuits, can lead to visible flickering or audible humming. [Pre-installation checks]: Ensure that the bulb’s wattage does not exceed the maximum value stated on the adapter. Before installation, check that the spring contacts within the existing lamp holder are not bent or corroded. Do not use in completely sealed luminaires unless it is confirmed that there is sufficient air circulation for heat dissipation.
