Tempered glass for MH lens...
 

Anyone know where to find glass for my 250 MH light? I had a thin non-tempered one and surprise-surprise, it cracked from the heat. The lens is approx: 15" x 8.5".

Thanks for any input

I had to find glass as well for the bogus light that was sold to me. What you can do
is go to your local glass shop and see if they have high heat glass in stock. Otherwise
they more then likely have to order tempered for ya.

Any glass shop should be able to get 3mm tempered glass cut to the size you need, phone around and find the best deal. Some will apply a minimum charge so it could vary.

Oh yea they can get it....it will most likely have to be ordered though.

Think it has to be ordered,you can't cut tempered glass.

You might want to check for something special about the glass, simply replacing it with regular glass that you get tempered may not be that simple.

HQI lamps have a UV filtering quartz outer glass, so you don't need to have a quartz glass lens. You needed a quartz lens with the old Osram Powerstar lamps.

I was under the impression the HQI or DE bulbs don't have the UV filtering outer glass and require tempered "low emissivity" glass. It's the Mogul or SE bulbs which have the UV filtering outer glass and don't require any additional requirements for a glass shield.

They can be found in any glass shop ( 20 / pane). Actually DE have the UV filter. The extra glass shield is to protect you from an exploding DE.

My Mh have Low E tempered glass on them and are DE.
