Hello everyone,

As the end of fluorescent lighting approaches, we’ve started to see many fluorescent tubes—such as special-size models, very cheap no-name halophosphate types, and Panasonic branded ones like the FHF32—marked with long alphanumeric manufacturing codes like the one shown in the image.

The only common factor seems to be that they are made in China.

Does anyone know which manufacturer actually produces these?

On the packaging of Panasonic fluorescent lamps sold in China, the manufacturer is listed as Beijing Matsushita Lighting Co.Ltd. I believe that the Japanese version and the Chinese version might use the same production line.
