I did a test with a 400W Mercury Vapour HighBay and started finalising the suspension hardware.
A test with the bare bulb hanging in the workshop proved without a doubt that the light output has a very prominent green tinge. I was also a little disappointed with the light output.![](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh4JEQCFWxp8H0RcYajt7xPddNGsZC-v1PigWWKyWp43OXohTZ59NAyU2-khKBCT7VY6Iy9facWdEFejtn6-LfJnQyhzRVSdY6G8M9ISL54YvgFwLmZtwngZ2Q0jzXEojQgA-hN5Sjz-TM/s320/blogger-image--231139161.jpg)

While I left the luminare running to allow mumbling at it I set about shortening the chains and temporarily hanging it off the end of a 6m length of scaffolding pipe I had handy.
That ugly flange is going to be replaced by a repurposed KEE gate hanger with a big shackle.
With the three phase variac on the end of the pipe as a counter weight, I precariously balanced the pipe on the rim of Big Scary Fan™
This thing is actually starting to come together :-) Next on the list is to make a stand to support the pipe and find a better light source.
