The arc of my Venture MH-DE 70W/UVS/PDX pink MH lamp

The arc colour is uniform, despite created by several halides and not by one.

I remember some of these Pink 70w MH lamps installed in flood lights on a car sales and on a farm here and they seemed to outlast 'White' and any other color MH lamps. The pink MH lamps lasted a good 8-9 years on the farm and car sales here before going dim then totally. EOL

The white ones usually uses rare-earths, thallium and sodium. This one have indium-sodium-lithium. Some pink MH lamps don't have lithium or have small amount, but this one have very large amount of lithium.

I should really get some coloured halides while I still can tbh.

Pink MH lamps were available up to 400W, Green MH lamps up to 2000W and blue up to 3000W.

I wonder if you removed all the halide salts out of one of these, you would have a mercury lamp you could use on SON gear? Smile

I imagine that would affect the arc voltage a bit?

@AngryHorse To be honest with the space in a 70W Mh lamp I would expect a lamp voltage of around 30-40V
