We think everyone can agree that lasers are an asset to any event and are one of the greatest effect fixtures you can have on your rig. Nowadays, lasers can include multiple patterns, feature a ton of effects, and project beams in bold colors such as red, green, blue, magenta, violet, cyan and yellow. The first step to creating a great laser show is knowing how to properly use them.  See below for some helpful hints to remember when it comes to operating lasers.

Safety First
Light emitted from lasers is a thousand times more concentrated than light from any other kind of light source. This concentration of light can potentially cause eye injuries, so whatever you do, don’t shine the laser directly into someone’s eyes. Lasers sold in the US must comply with FDA/CDRH standards and don’t require a variance. As you set them up, make sure to follow ALL instructions listed in the individual user manuals provided with each fixture and you won’t have anything to worry about.

Haze and Fog Complete Me
Adding haze or fog to your event will drastically increase the effect of your laser by making all of the beams visible. You’ll be able to create mid-air beam looks that will span the entire room and can be moved and zoomed to fit the venue perfectly. Just a little bit goes a long way, so don’t feel the need to completely fog out the room and overwhelm your guests.

Effects Galore
With laser sky effects, laser webs, star fields, and swirls, there are so many different types of lasers on the market to choose from.  You can choose from ultra compact, plug-and-play lasers which project red and green effects, lasers that project a rippling aura effect, or color-mixing lasers that mix to create yellow, cyan and magenta beams and are operated using DMX.

Selecting the perfect laser will depend on the size of your venue and the type of event you are hosting. Regardless of the fixture you choose, if you combine it with haze or fog, you will give your audience an awesome light show they’ll be sure to remember. In case we didn’t give you enough information, here’s one more fun fact of the day – LASER stands for “light amplification by stimulation emission of radiation.”
