Mysterious 3w T4 fluorescent lamps « on: February 16, 2025, 12:34:09 AM » Author: LightsAreBright27
I found two of them with fixtures in a bed frame, thinking they were F4T5. But they are shorter and thinner, more like 3w or 3.5w in T4. Both are blue, and the shade is similar to my 12w T4 blue tubes. The fixture can't fit F4T5s and uses a cold cathode electronic ballast. Both the lamps and fixture have no branding or wattage etch, only 220-240v on the fixture. Does anyone know anything about these? Anyone else has them?

I've seen them too, in daylight, pink, blue and green. Only thing is that they are usually soldered with no endcaps, and majority don't have filaments (CCFL). I kinda wish it was a standard, like a mini F4T5.

@dor123 I have three different colours of T4 in 12w. But This 3w one is too short.
