Diffent types of Light

There are many different types of light available for use. The main three I will be talking about are; Incandescent/Halogen, florescent and L.E.D. 

Warm white vs. cool white
Warm white light recreates the look of incandescent light bulbs (a yellowish look), where as cool white is very white.

Incandescent/Halogen light bulbs are the standard light bulbs that have been used for years and are still being used. Halogens save a little bit more electricity than incandescent bulbs but are still the least efficient than the other two. These lights are very inefficient, they use a lot of energy to produce light. In a place like a car this may not matter, because the electricity is available as long as the vehicle is running.

Fluorescent light bulbs are more efficient and a way of reducing electricity cost.  This type of bulb can save up to 80% on light bulb cost, but they contain harsh chemicals that can be dangerous if the bulb is broken. Available in warm white and cool white. These bulbs are typically not found in most cars.

L.E.D. bulbs are the most efficient light bulbs of the three. They are relatively new, so they are the most expensive. These light bulbs can save up to 90% of light bulb electricity cost, and they last the longest. They are also safe for your home and shock resistant, so they are more durable than other bulbs for use in cars. Available in warm white and cool white.

For home use, I would recommend using L.E.D. light bulbs where ever possible, and fluorescent for when you can not use L.E.D. This light set up will be the most efficient and provide a great light output for the cost. You may have to pay extra, but they save you money over time.

For car use, I would recommend using L.E.D. in every place interior and exterior, except for headlight use. L.E.D. will give you more light output than the stock light bulbs while still using less electricity and are instant on/ instant off which makes other drivers see your lights sooner, which results in safer driving.

How To Clean And Maintain Your Paintball Marker

Cleaning notes: This is a general explanation for use with most paintball markers. If you are looking for an in depth do it yourself gun specific cleaning this is not for you.

Caution before you start, remove ammo and propellant. For example remove the co2 tank and paint balls. It is also a good idea to keep the gun on safe.

If you have ever used your paintball gun during a full day of play or even one game in some cases, your gun may have been shot, gotten dirty, or have broken paint inside it. This guide will help you clean your gun for storage or in preparation for the next game. NOTE: paintball guns should be cleaned after each day of use so that the internal parts do not get gummed up or stuck, and then would be in need of repair.

1.) First of all to clean the outside of the gun, you will need to clean any dirt or paint off of the outside of the gun using a damp paper towel (caution: if your gun has electronics do not get any water near them), then follow up and dry with a dry paper towel.

2.) Once the outside of your marker is clean, proceed to remove the barrel and squeegee or clean by sliding a wet paper towel down the barrel followed by a dry one. It is much easier to use a squeegee and I recommended you do so, it is also great to have one on the field when you brake paint in the barrel while playing. (NOTE: some guns may have the ability of cleaning the barrel without removing it from the gun (For example, through the hopper feed neck.)

3.) Next with the barrel off, use a paper towel to clean the area where the barrel screws on to the marker, and the front of the bolt. Some guns it is very simple to remove the bolt completely and clean the entire upper part of the marker.

4.) After, remove the paintball hopper and check to see the inside is clean, if not clean with water and set aside for it to dry, speed up drying with a dry paper towel. With the hopper off, use a paper towel to clean the neck where the hopper slides on, the top of the bolt, and the bolt area when it is in the cocked position.

5.) Lastly, put about five drops of paintball gun oil in the hole where the co2 tank screws on and then fire a few shots. What this will do is lubricate all of the moving parts and finally your marker is ready for storage, or you have just prepared it for another round of play.
