2D Butterfly Fluorescent Lamps
- Shallow Square Footprint: The folded tube uses fixture width efficiently where enclosure depth is limited.
- Broad Emitting Surface: Two adjacent loops distribute the luminous tube across more of the fitting face.
- Holder-Specific Connection: Distinct two-pin and four-pin cap formats support the matching lampholder architecture.
- Serviceable Lamp Format: The lamp can be replaced separately from a suitable luminaire and its operating gear.
