In a car you can.

Very Funny Ian.

Are you sure this is a M-400 not a M-250?

@Jace the Earliest M-250's that have M-400 Housings,250 Watt Lamps and Polycarbonate Refractors?

Yep but overtime refractors gets replaced and can get replaced with glass....and only those without the thumb latch like the above could be a M-250..

Ian said its a 400w so its a M400.

im sure it's a M400 but how could you tell the diffrence through the glass?

If it has the smaller 175w or 250w lamp inside, chances it may be a M250, especially if it is the oldest model in silver without the thumb latch.

Unfoutunatly, we won't know unless the light is opened up. It's not common for utilities to do this, but it may have a cram lamp.

There's no such a thng as a MV cram lamp from my knowlege....plus...its actually kinda easier than you think....you have to look carefully....the M-250 has LOOOONG socket inside....

Yes there is. I used to own one. It's only made by Plusrite.

Most likely a utlity wouldn't use a Plusrite anyway...its one of the worst quality lamps out there.... plus if it was 175 or 250 watt...it would be centered in the reflector because of longer socket....and yes you'll be able to see through glass....you need an experienced eye...like me! If it was a cram lamp MV....it would totally be off centered on the reflector

I kinda recall seeing a 175w mercury cram lamp before but I can't seem to find any info on it.

Alain has a 175 Watt MV Cram Lamp,its an ED-17 Envelope with a Medium Base i believe.

I have 150 watt HPS cram lamp and 175 watt MH cram lamp and some other wattages of MH cram lamps...but I haven't seen any MV ones.

Actually Jace, I wouldn't be able to see through the glass because my vision is blury without my glasses. If you want to know what my vision looks like, look at a few of my pictures in the gallery. I actually see the lights on the pole in person just as blury as when on the website.

Nice sense of humor....

But I must admit.....it's harder to see on GE refractors than the OV-25 refractors because the OV-25 refractors has much clearer spots on the sides....

Your camera probably needs glasses

You know, I actually tried to take a picture using my glasses over the camera lens, but it focused in on the glasses. It was a cool pic though. My OV10 lens is virtually see-through. Even before I opened it, I knew there was a coated BT lamp inside.

You probably just need to learn how to do a focusing on cameras....you need to do a half press on the camera (press lightly on the shutter) it would do a focusing measurements.....then when the picture looks good on the screen....SNAP IT!

I'll try that. thanks.
