GE F36w-1M/33 1 Metre Fluorescent Tube

GE F36w-1M/33 1 Metre Fluorescent Tube

Click to view full size image

Here you see a pair of GE 36w 1 metre (actually 970mm and sometimes named as such) colour 33/640 fluorescent tubes, BNOS but without sleeves.

Note that these run at 0.56a, not the usual 0.44a of a common (UK) 36w 4ft tube.

At least I know these normal European linear 36 Watts bulbs delivers 440 mA load

Pretty, please no more Chinese failure.

0.43A to be correct. I have already seen some old ballasts for 40W T12 (which have the same specs than F36T8) rated for 0.42A. These 1 Meter tubes have indeed a different current and voltage rating.

36/40W 1.2m (4ft) -> 0.43A
36/40W 1.0m (~ 3ft) -> 0.56A
40W 0.6m (2ft) -> 0.88A

Those 1m tubes will do well on current as low as 0.35A

BTW is the lumen efficacy of 0.6m 40W tubes is lower or higher than 1.2m 40W tubes?

You’re welcome Robert 😉

The 0.6m 40W is rated at only about 1800 to 2000lm - depending on the colour temperature. The phosphor will degrade faster than usual in this higher loaded tube.
