FireFly FF-371 Digital Lightning Simulator with Internal Audio

In stock
The most advanced lightning simulator, the FireFly® FF-361, has been retired to make room for the new FireFly FF-371. The FF-371 retains all of the features of the FF-361, and adds a newer, faster processor, radically increased memory, a full-color LCD display, a user-adjustable audio delay, and user-adjustable hysteresis to create the new leader in lightning simulation.


We took the popular FF-361 back to the drawing board. The new FF-371 features a new higher-resolution full-color display and a new, faster microprocessor. We also added a selectable audio delay, so the lightning flash can precede the thunder as in real life if you desire. Also new in the FF-371 is the addition of hysteresis. It’s a selectable delay on the decay of the LED. While not an issue with incandescent lights, most LEDs react nearly instantaneously. That’s good for a quick flash, but lightning decays over a few milliseconds. In real life, it builds up, then decays rather than going from 100% on to 100% off. This will help with realism when using LEDs, especially quick reacting ones.
The FireFly® FF-371 retains the FF-361’s multiple internal audio tracks. You can still quickly choose between two (2) continuous loops and three (3) triggered tracks. There’s an internal timer, with both timed and random options. Then we added a timed option on the external trigger. Place your trigger sensor where you want it, but delay the thunder and lightning until the visitor advances into your scene. We’ve added some really sophisticated audio switching for those of you using your FireFly® for special effects other than lightning. The new unit includes a complex test routine that will not only confirm proper operation of your FF-371, it will also test the compatibility of third-party LED fixtures. And for you power users, we also added thermal protection to shut the unit down in the unlikely event that it would overheat.
If all that isn’t enough, even though there are some very powerful and complex options available, the FF-371 will work right out of the box. If you get lost or confused with the settings, simply do a factory reset and you’re back up and running within seconds. Plug in some lights…  connect your audio system and plug the FF-371 into an ordinary wall outlet and the storm will begin in seconds. If you have customized your system, it will remember your settings, even when powered down or unplugged. User manuals, audio tracks, and some bonus music tracks are all included on a custom USB flash drive.


FireFly® model FF-371 is a premium microprocessor-controlled three-channel lightning simulator which offers two channels of lightning, plus a third dedicated dimmer channel. Two channels can be used for lightning effects plus one channel can be connected to house lights, porch lights or even a lamp in the window for dimming effects. When there is a close “lightning strike”, not only do you see the lightning flash, but lights connected to the third channel will dim and flicker as though power is about to go out. New on the FF-371 is a jack for pulse width modulation (PWM) control of low-voltage lights. With PWM lights, you won’t need to run 120-volt extensions to your lights. Low-voltage lighting will make a safer haunt experience.



A maximum of 3,000 watts of lights can be connected to the FF-371.



Not only will the test routine confirm proper operation of the FF-371, it will also test compatibility of connected lights in two ways. First each light will individually ramp from off to full brightness to confirm that they dim appropriately. Next, each light will be rapidly pulsed to confirm they have adequate response time for lightning simulation.



No more special cables or adapters required when doing special effects with the FF-361. You can easily choose the audio source for each channel independently. Even if you choose monaural audio for your lightning simulation, the FF-361 will still pass stereo audio through to your speakers.



The internal audio tracks use lossless (uncompressed) 16-bit audio sampled at 44.1KHz for true CD quality, resulting in far better audio than MP3 or other compressed files.



To protect the user as well as connected equipment, the FF-351 utilizes an isolated switch mode power supply as well as solid state optical isolation to separate high voltage circuits from audio and control circuits.



FireFly® was designed to support a wide variety of lights. For best results, we recommend our ProLight™ 400 high-power LED light, which we designed specifically for lightning simulation. The intense white light and quick reaction time of these lights is unsurpassed in simulating lighting. FireFly® also supports  some dimmable LEDs, conventional incandescent, and Halogen bulbs. And with the new PWM channel, you can use compatible low-voltage lights a s well!



In order to insure that lights fire quickly and offer the appropriate dynamic range, adjustable threshold controls are accessible via the Menu button for easy end-user optimization.



At any time, FireFly® controls can be restored to factory default via the Menu control.



The FF-361 uses digital phase cut dimming so that the intensity of the light directly corresponds with the amplitude (volume) of the thunder.



Lights Alive provides an unprecedented three (3) year limited warranty on all FireFly® models. We will repair or replace (our option) any unit that fails within three years of the purchase date due to defective materials or workmanship. This warranty will not apply to units that have been modified or that have been subjected to physical abuse. For warranty service, simply call or email Lights Alive for a return authorization number, then return the unit, prepaid, to Lights Alive along with your proof of purchase. Please insure your package as we cannot be responsible for damage incurred during shipping. We will promptly repair or replace your unit and return it by the most economical means. If you prefer expedited shipping, please contact Lights Alive for shipping costs.



Regardless of its age, Lights Alive currently offers 50% of your documented purchase price toward the purchase of any higher model FireFly lightning controller. Simply call or email us for details on how to return your existing unit. We’ll send you an invoice for the new model and ship it to you immediately upon receipt of the upgrade costs. This offer may be modified or discontinued without notice and is good only for upgrades purchased directly from Lights Alive.



FireFly® FF-371 has built-in 16 bit, 44.1kHz CD-quality audio, which can be played continuously (“looped”) or triggered externally for “lightning on demand.” In the event a user wants to use their own audio, FireFly also operates with standard line-level audio via a conventional 1/8” stereo jack. Various adapters and cables are available from Lights Alive or through your local electronics store. Please consult with Lights Alive if you have connection questions.



FireFly® is proudly designed and manufactured by Lights Alive in the United States.



FireFly is housed in a stackable case, making it easy to stack multiple units into a single neat unit.
