Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang LEDVANCE/ SYLVANIA dari 3G Electric.
What is the difference between LEDVANCE/SYLVANIA UL Type A and UL Type B U-bend lamps?
UL Type A U-bend lamps are plug-and-play replacements that operate directly on existing fluorescent ballasts, simplifying retrofits without rewiring. UL Type B lamps are ballast-bypass models that require direct-wire installation, eliminating the ballast from the circuit. Both types are available in LEDVANCE/SYLVANIA's U-bend line with 6-inch leg spacing and shatter-resistant construction. The choice depends on whether you want to retain or remove the ballast. Type A is typically used where ballasts are in good condition, while Type B is chosen for new installations or where ballast maintenance is undesirable.
What color temperatures are available in LEDVANCE/SYLVANIA U-bend LED lamps?
LEDVANCE/SYLVANIA U-bend LED lamps are offered in several color temperatures to suit different environments. Common options include 3500K neutral white, 4100K cool white, and 5000K daylight. For example, the 13-watt UL Type A models come in 3500K and 4100K, while the 15-watt UL Type B models include 3500K, 4100K, and 5000K. These options allow specifiers to match existing lighting or meet specific task requirements in commercial and industrial spaces.
Are LEDVANCE/SYLVANIA CFL twin-tube lamps dimmable?
The LEDVANCE/SYLVANIA CFL twin-tube plug-in lamps, such as the 13-watt T4 with GX23-2 base, are non-dimmable. They are designed for use with compatible ballasts in commercial and industrial fixtures. For dimming applications, consider LED alternatives that are explicitly rated for dimming, such as certain U-bend LED models in the LEDVANCE/SYLVANIA line. Always verify dimming compatibility with the specific ballast or driver being used.
What is the wattage equivalency of LEDVANCE/SYLVANIA 13-watt U-bend LED lamps?
The 13-watt LEDVANCE/SYLVANIA U-bend LED lamps typically carry a 30-watt equivalency, meaning they replace 30-watt fluorescent U-bend lamps while consuming less energy. This is specified for models like the UL Type A plug-and-play lamps. The 15-watt UL Type B models have a 50-watt equivalency. These equivalencies help in comparing light output and energy savings when retrofitting existing fluorescent troffers.
Do LEDVANCE/SYLVANIA U-bend LED lamps have shatter-resistant construction?
Yes, many LEDVANCE/SYLVANIA U-bend LED lamps feature shatter-resistant construction. This is indicated in the product specifications for both UL Type A and UL Type B models. Shatter-resistant lamps are beneficial in environments where glass breakage could contaminate products or pose safety risks, such as food processing or industrial settings. The shatter-resistant design helps maintain integrity if the lamp is impacted.
What base type does the LEDVANCE/SYLVANIA 13-watt CFL twin-tube lamp use?
The LEDVANCE/SYLVANIA 13-watt CFL twin-tube plug-in lamp uses a 2-pin GX23-2 base. This base type is common in compact fluorescent fixtures for commercial and industrial applications. The lamp operates at 3000K color temperature and is non-dimmable. It is important to match the base type and ballast compatibility when replacing lamps to ensure proper operation.
