The time period refers to a selected sort of sunshine bulb characterised by its G9 bi-pin base and a most energy consumption of 25 watts. The “G9” signifies the bodily connector, that includes two pins spaced 9 millimeters aside, designed for simple push-fit set up. The “25 watt” specifies the uppermost restrict {of electrical} energy the bulb will draw throughout operation; exceeding this wattage might harm the fixture or bulb itself. For example, a compact halogen or LED bulb utilized in chandeliers or desk lamps might conform to those specs.
This sort of bulb is usually chosen as a result of its compact dimension and vitality effectivity, notably in its LED iterations. The restricted wattage promotes lowered vitality consumption, doubtlessly decreasing electrical energy payments and minimizing environmental influence in comparison with higher-wattage choices. Traditionally, halogen bulbs with this base and energy ranking have been prevalent, however developments in LED expertise have led to extra environment friendly and longer-lasting replacements that meet the identical specs.
