What is a dichroic filter?

I wasn't sure either, so I looked it up..! Apparently, it's a filter designed to selectively pass light of a small range of colours while reflecting others.

I love these lamps, they are so well made, the build quality is amazing. I have a couple of Iwasaki MH lamps, they're almost works of art

What is a dichroic filter?


The dichroic filter is the iridescent coating you see on the arc-tube shroud. What a dichroic (dye-crow-ick) filter does is pass one color and reflect the polar opposite. Think of the Selective Yellow head lights than France required up until 1993. Initially, they used cadmium to create the yellow filter, but when they realized that it was a carcinogen, they had to come up with an alternative, and the dichcroic filter was created. (They were most commonly found on halogen lamps.)

Here's a picture of an H3 halogen lamp intended for fog light use that has a dichroic filter: https://www.lighting-gallery.net/gallery/displayimage.php?album=4812&pos=3&pid=142849

Your mission - should you choose to accept it - is to save unique and rare HID lighting before it's all scrapped.

I once had a car with a couple of French H4 headlamp bulbs. They simply had a plastic yellow cover over the standard H4 lamp. You could actually take them off and put them on new bulbs to save having to buy them ready fitted, which tended to cost more (and not easy to find in the UK).

Yep, I've seen pictures of those reusable yellow glass H4 balloons. (Do you really think that they were plastic? )

Definitely, I broke one

I quite liked them, they were easier on the eyes in fog. Less light output, certainly, but easier to drive with.

Yep...I'm currently using Osram Allseason Super H4's in my truck for the same reason...and I also like they way they look!
