Q. My Viridian is not functioning correctly. What should I do?

A. First, like most electronic devices, many problems can be fixed by simply removing the battery and replacing it-effectively restarting the unit. If this doesn't work try replacing the battery with a new one (Viridian batteries can be purchased here and here). If that doesn't work, please contact us via phone or email so we can service your unit.

Q. What is the difference between the Viridian C5L and new Viridian X5L?

A. The biggest differences between the C5L and X5L is light output and size. The C5L is roughly half the size of the X5L. However, the X5L features a 160 lumen tactical light (190 on strobe mode) while the C5L features a 100 lumen tactical light (140 on strobe mode).

Q. What is the difference between the Viridian X5L Gen 1 and Viridian X5L Gen 2?

A. The biggest differences between the X5L Gen 1 and Gen 2 are the distinct design differences, battery usage, and light output. The X5L Gen 2 has a much sleeker design than the X5L Gen 1, the Gen 1 uses one CR2 battery while the Gen 2 uses one CR123 battery. The light output is almost doubled on the Gen 2 from the Gen 1-from 100 lumens to 160 lumens. The X5L Gen 1 was discontinued in late 2010. The Gen 2 can be seen here.

Q. How far can you see a Viridian green laser during the day and at night?

A. It all depends on outdoor lighting conditions and what surface you are shinning the laser on but at a minimum you will be able to see a Viridian green laser sight at 25 yards during the day and up to 100 yards. At night, you can see the laser up to two miles.

Q. What maintenance should I do with my Viridian?

A. Front Lens Cleaning: Use a moistened cotton swab to periodically clean the front lens of gun powder residue. This step is important to prevent any degradation in the quality of the green aiming point and/or beam.

A. Exterior of Unit: Clean the Viridian by wiping with a soft, damp cloth. Standard gun cleaning solvents may be used to clean stubborn areas.

A. Electrical Contacts: For cleaning of all electrical contacts, use a cotton swab dipped in alcohol. To remove heavy build-up on the contacts, carefully rub with a standard pencil eraser (be sure to thoroughly remove eraser residue).

Q. How long should I expect my batteries to last?

A. For Viridian's that run on 1 CR2 3v laser run time is 4 hours on constant laser, 7 hours on pulsing laser and 60 minutes on laser and light. For Viridian's that run on 1 CR123 3v, laser run time is 7 hours on constant laser, 10 hours on pulsing laser, and 80 minutes on laser and light.

Q. How do I change the batteries in my:

A. Gun Specific Viridian-Use a pen to depress tab on bottom of the unit. The battery door will pop out. Make sure the negative side of the battery is facing into the Viridian when you put the battery door back on.

A. X5L Gen 1-Press the edge of the light carrier in and turn counter clockwise. Replace battery and insert light carrier back into the unit, push in and twist clockwise.

A. C5 Series-Use a coin or flat head screwdriver and turn battery door until it loosens. Make sure the positive end of battery is facing into the unit when battery door is replaced. Also make sure threads of battery door are lined up correctly to prevent cross threading.

A. X5L Gen 2-Turn the tactical light lens counter clockwise and remove. Insert CR123A 3v battery positive side first. Replace tactical light lens and turn clockwise until it reaches its stopping point. To ensure proper connection, the battery door must be "very tight".

A. X5L RS-Turn the tactical light lens counter clockwise and remove. Insert CR123A 3v battery positive side first. Replace tactical light lens and turn clockwise until it reaches its stopping point.

Q. What kind of batteries should I use in my Viridian?

A. If you have a gun specific or C5 series Viridian you can use any NON-rechargeable lithium CR2 3 volt battery. If you have an X series laser (X5L Gen 2 or X5L-RS) you should use NON-rechargeable lithium CR123 3 volt battery. We recommend using Viridian Tactical Energy Batteries. They can be found here and here.

Q. Can I use re-chargeable batteries in my Viridian?

A. No. You should not use rechargeable batteries in your Viridian. We recommend you use Viridian branded batteries that can be found here and here.

Q. How do I adjust my Viridian for Windage and Elevation?


  1. Set up a target with a clearly visible aiming point.
  2. Mount the Viridian onto the weapon's accessory mounting rail (see "Mounting" procedures).
  3. Turn ON the Viridian.
  4. While aiming the pistol through the iron sights, use one of the two provided adjustment wrenches (smaller sized) to adjust the visible green point of the Viridian. Turn the windage and elevation wrench to superimpose the Viridian's aiming point over the weapon's iron sight aiming point.
  5. Aim and fire a three round shot group into the center of the target's aiming point.
  6. Compare the impact point of the shot group to where the Viridian's aiming point was on the target to ensure they line up.
  7. Make the necessary adjustments to the Viridian to ensure its aiming point and the shot group are aligned.
  8. Turn the unit OFF.

Q. Which way do I turn the allen wrench to adjust the laser left, right, up or down?


Windage - To adjust the laser to the RIGHT, turn COUNTER-CLOCKWISE. To adjust the laser to the LEFT, turn CLOCKWISE.

Elevation - To adjust the laser LOWER, turn COUNTER- CLOCKWISE. To adjust the laser HIGHER, turn CLOCKWISE.

Q. At what distance should I sight my Viridian in at?

A. If you are using your Viridian for in-home protection we recommend you sight your Viridian to the distance of your largest room in your home. If you plan to conceal and carry your Viridian, you should sight your Viridian to a normal handgun range (7-12 yards).

Q. What is parallax error OR "Why isn't the gun and laser dot aiming at the same point no matter the distance the handgun is aimed."

A. You will see a minor difference at varying distances. You will want to zero it in for whichever distance it will get used most. A good rule of thumb - if you are using your Viridian for in-home protection we recommend you sight your Viridian to the distance of your largest room in your home. If you plan to conceal and carry your Viridian, you should sight your Viridian to a normal handgun range (7-12 yards). Fortunately, since the laser is designed to emit as close as possible along the line of fire, it should not make too much of a difference. This minor error is referred to as "parallax error" and the math follows as such. If your target is half the distance from where you are zeroed in (i.e. zeroed in at 20 feet but facing a target at 10 feet) your shots will hit 1 inch higher than your green laser aiming point would indicate. The converse is also true.

Q. Why was my credit card charged before my order shipped?

A. Our secure order processing system does not store your credit card information and is not capable of deferring credit card charges. Credit cards are charged immediately upon purchase.

Q. Why was my credit card declined?

A. Upon clicking on the "Place Your Order" button at the last step of checkout, your order and credit card information will be processed. If your credit card is declined, a message will appear on the page with the reason why it was declined. If it is declined as a result of an AVS mismatch, please verify that the billing address information you are entering on the website is an exact match to the billing address information on file with your credit card issuing bank. If your card is declined as a result of the card code mismatch, please ensure that you are correctly entering the 3 or 4 digit code that appears on the front or back of your card (varies by card type). If your transaction is otherwise declined, please ensure that you have sufficient funds available in your account to complete the transaction, or contact your bank to inquire about any holds that may have been placed on your card.

Declined transactions may appear on your billing statement as pending transactions. Within 5 business days, your bank will remove these pending transactions from your account. Because the transactions were declined, they will never be posted or permanently charged to your account. Unfortunately, during that time that the bank is processing the pending transactions, those charges will be deducted from your account balance. These funds are not being held by, and may have their pending status removed only by your bank.
