Why Orange MH lamps don't contains tin halide « on: April 19, 2026, 07:56:24 AM » Author: dor123
Pink metal halide lamps often have tin halides to filter the indium line making the lamp redder.
Why orange metal halide lamps like the BLV ones don't have tin to filter the blue and green mercury lines so that the color would be oranger?

I have still not yet found firm evidence of tin being used in pink lamps - do you have a spectrum or some other material that proves this?  I would expect tin to desaturate the colour due to its very broad spectrum, more than it saturates it by blue absorption.

Here is the spectrum of my Venture MH-DE 70W/UVS/PDX lamp: https://www.lighting-gallery.net/gallery/displayimage.php?pos=-231287
I think that the halide that account for the vapor afterglow is tin, because of the continuous radiation and the fact that tin absorbs the blue part of the spectrum.
