Thorn Alpha 6 200 Watt Integral Gear

This lantern is the longest (and heaviest) out of the three Alpha 6s. But then, when you look at the gear you can see why...

The components are placed in the same places as in the 140 Watt Integral version; however, this ballast will only run 200 Watt SLI/H lamps and no SOX lamps. The Bosch capacitor is dated 01/78. A 5 amp cartridge fuse is installed in the carrier located in the centre of the connector block.

This is the only label in this lantern, and I can't help thinking it sounds like a Biblical reference!

This lantern resembles the later 135 Watt SOX Alpha 4, with the GRP canopy and aluminium shoe. Earlier models would have had aluminium canopies.

On Friday, 30th January 2004, this lantern was powered up for the first time in its entire life!

The initial switch on! Something that really surprised me was that the warm up colour was mauve, as opposed to the neon-red glow in SOX lamps. The reason behind this is that the start-up gas is Xenon.

Only a few minutes later, the mauve was more or less completely gone!

A few minutes later still and the lamp is almost up to full power.

Full brightness was now reached - and the familiar glow from low pressure sodium lamps was seen.

The lantern was mounted to an AC Ford AC872 wall bracket on Friday, 19th August 2005.

You would never think that this lantern was related to the Beta 79 below it!
