Philips FGS 104
Lantern acquired in September 2005.
In the Derbyshire area, the 55 Watt SOX version of this lantern, the XGS 104, was quite common; however, this is the first time that I have seen a compact fluorescent example.
The lantern is the larger version of the MI 26 / XGS 103; however, the bowl on it opens from the side rather from the back.
The GRP canopy was a little dirty when received, but it cleaned up quite well.
Even though a compact fluorescent lamp is fitted, the refractors still manage to break up the shape of it with success.
The lampholder and support are exactly the same as the ones used in the Residium. The lamp support also acts as a 'heat cap' - allowing the tube to achieve a higher relative luminous flux at lower temperatures.
The electronic ballast has to be fitted at an angle due to the connector block being in the way.
The lantern was fitted to an AC Ford AC872 wall bracket on Saturday, 1st October 2005.
It was then powered up - after a few seconds, the lamp struck up and was virtually at full brightness straight away.
Lantern warm-up video:
Testing with my energy monitoring device revealed the following results. Naturally, with the capacitor disconnected, the Power Factor was less than impressive.
| Test Voltage (V) | Current being drawn at full power (A) | Measured wattage (W) | Apparent Power (VA) | Frequency (Hz) | Power Factor | True Power (W) | Difference to rated wattage | Percentage Difference |
| 233.7 | 0.14 | 32 | 33 | 50 | 1 | 32.72 | -3.28 | -9% |
