Lamp Retrofit and Replacement
Replacing halogen and incandescent lamps in existing fixtures requires exact base compatibility, consistent light output and dimming performance across different bulb types. Well King supplies retrofit LED bulbs and downlights that match the base, lumen output and dimming behaviour of legacy lamps, ensuring seamless replacement without rewiring or fixture changes. The solution covers candle bulbs, A80, G40/G45/G50, A60, PAR20/PAR30/PAR38, and multiple spot light bases including GU10, MR16, E27, E17, E11, and EZ10.
Pain Points We Hear
- Existing halogen fittings have no dimming compatibility with standard LED bulbs
- Candle bulbs from different suppliers vary in colour temperature and lumen output
- Downlights installed in recessed ceilings cause glare due to lack of anti-glare housing
- Bulbs with low CRI make colours appear dull in retail and residential spaces
- Dimming range is too narrow or flickers under 5-100% on retrofit bulbs
- Incorrect base size causes fitment failure in existing fixtures
What the Buyer Needs
- Exact base match for GU10, MR16, E27, E17, E11, EZ10, C38, C37, A80, G40, G45, G50, A60, PAR20, PAR30, PAR38
- Consistent CCT and CRI across all bulb types used in the same space
- Dimming range from 5% to 100% with flicker-free operation
- Anti-glare housing on recessed downlights to reduce visual discomfort
- Instant-on without warm-up delay when replacing incandescent lamps
- CE, RoHS, FCC, SAA, PSE certified products for compliance in export markets
