Hi, I'm new to Hammer and I'm making a TF2 map. I am ok at detailing maps, but I want to know three things on lighting. I highly appreciate it if someone can help me:

1. How do you make these beams come from the lights? Is there an effect tool, or do I use "light_spot"?

2. How do you make lights for props? For example: The underground computers from 2fort.

3. How do you create a light texture like this?

I've provided images numbered to my questions:

1) It's the point_spotlight entity.
For the 2) and 3), this VDC article will probably provide you with some basic knowledge: Glowing Textures

Ok so I tried what Kobolite gave me, which was the lighting library, and it didn't work. I copied and pasted one of the lights and I got no beam. Is there a setting that I disabled by mistake?

The env_sprites, on the other hand, worked fine.

I'm pretty sure I did, I took the model and the light_spot. I'm not sure what the point_spotlight is.

Oh I see now, I took a light without a point_spotlight, but I've found some other ones with one. Thank you so much.

Quick answer and info taken from sdk_ctf_2fort (the official .VMF file):

1) light_spot + point_spotlight combination
2) light_spot + point_spotlight combination
3) a brush face textured with lights/white001

If you wish to know the values and such:
1) light_spot - "Outer (fading) angle" : 70 /// point_spotlight - "Spotlight Length" : 256 | "Spotlight Width" : 64
2) light_spot - "Inner (bright) angle" : 35 | "Outer (fading) angle" : 46 /// point_spotlight - "Spotlight Length" : 150 | "Spotlight Width" : 80
