Any1 can identify this lamp?

Hi everyone,

I'm looking for the light source for my project, but I've had some trouble knowing how to translate "Metal halide" to spanish (If anyone knows please tell me!)

Another thing (The real reason for this post).

I was looking in a lot of stuff my dad keeps in the garage, and I found a "reflector" (I think), and I am wondering if I could use it as the light source.

I don't much about this stuff, so I am unable to identify what kind of light it uses, but it has a sign begind the "light bulb" (Its not ordinary incandecent) that says "Max 500W".

I attached an image of it in this post, if anyone knows what this is, and if I could use it as the light source I would be most grateful!

New info

Ok, i finally figured out how to remove the light bulb, and it says it's 300W, but I don't know what type of bulb is that, and if it could be used for building an LCD projector (I'm planning to use a 5 or 6inch LCD projection Panel).

So, I remain without knowing if it could be used, please help!

It's a 500W or 300W (250W ?) halogen lamp.
Don't look directly at it when plugging it in and don't touch the lamp. If you did, clean it with alcohol or something similar before reinstalling it.

Just out of curiosity, why do I have to clean it with alcohol if I touched it?

Also, it actually said 300W, would it be suitable for a DIY projector?

Thanks!

I don't think a 300W halogen is what you need for this project. You're better off importing a metal halide setup from the US.

I know nothing about projectors, that's why I answered only a part of your question.
When you touch the lamp with your fingers the grease or sweat or whatever hangs on your fingers 😀 will stick on the lamp.
The heat developed while burning is so high that the "whatever hangs on your fingers_and also_on_the_lamp" will burn into the glass and shorten the life of it.

Here is a good and more technical explanation of what I mean to explain.

Halogen Worklight

Here is a thread with the experiences of others using this type of light.

If you do a search for "shoplight" or "worklight" you will find others as this would be the common names for it.

I have used a light like this for an exposure unit in screen printing and they produce a ton of heat. Sorry, I don't mean to sound discouraging.

One question though: I read the main critic towards using that kind of lamp was the heat it produces (I let it on for a couple of minutes and yes, it was hot). Also, because light would not hit the LCD as paralel rays.

Question:

If I found a way not to worry about the heat, and use a fresnel lens placed between the light source and the LCD, wouldn't the fresnel make light hit the LCD as paralel rays? If so, at what distance should I put the fresnel from the LCD, at the focal point?

Thanks!

That sounds right.
