Emergency Solutions for LED Retrofit - IOTA Engineering

  • Linear, compact, or U-bent LED lights
  • Directly replace existing fluorescent lamps
  • Require AC input voltage

TLED Lamps are designed to convert the AC voltage coming from your fluorescent ballast to DC current. This allows you to simply replace the flourescent lamp with the TLED lamp without having to remove or re-wire the existing AC ballast.

Godson Tech contains other products and information you need, so please check it out.

Many IOTA Emergency Ballasts have been tested and verified compatible with select TLED lamps from major manufacturers. Use this reference to find a UL Listed and compatible Emergency Ballast for your TLED application.

  • Downlight or linear lamps
  • Feature internal drivers
  • Accept AC line voltage

Type B lamps feature a built-in driver that accepts AC line voltage. These lamps replace the fluorescent lamps and the fluorescent ballast to retrofit your existing fixture to LED.

Since Type B lamps are wired directly to the line voltage, they require an auxiliary source of line voltage as their emergency solution. IOTA offers several emergency inverter options to deliver line voltage to your LED retrofit fixtures.

  • LED tubes or arrays paired to an LED driver
  • Directly replace fluorescent lamps and ballast
  • Require DC input voltage

LED Retrofit Kits are designed to completely replace the fluorescent technology in your fixture. The driver/lamp combination included in the kit makes use of the fluorescent fixture in isolation.

Selecting the Optimal Emergency Driver Wattage

When selecting an emergency LED driver for your fixture, a common question is “how many lumens will it deliver?”  When commercial lighting was dominated by fluorescent technologies, emergency lumen performance was dictated by the fixed electrical characteristics of the fluorescent tubes/bulbs. With the advent of LED technology, our new solid state lighting loads are no longer ‘fixed’ electrically and in fact can be an almost infinite number of voltage and current combinations. Rather than the lumen performance being a trait of the lamp, it is now a result of all of the components used to create the luminaire and is described as efficacy (ie. delivered lumens per watt). From an emergency lighting perspective, calculating lumen performance is now simply a matter of multiplying the efficacy of the fixture by the wattage supplied in the emergency mode.

IOTA® constant power emergency drivers are rated by wattage, allowing you to quickly and efficiently determine which emergency drivers are right for your luminaire’s efficacy. Using a 100 lumen per watt baseline as a common efficacy, multiplying the emergency driver wattage by 100 provides a general lumen output: ILB CP07 = 700 lumens, ILB CP10 = lumens, ILB CP12 = lumens, etc. 

Read our Contractor Emergency Lighting Insider to understand more about the ease and the two primary advantages of IOTA's patented Constant Power emergency driver design.

Also available is our convenient Constant Power Lumen Reference Chart that quickly identifies available CP models per desired lumen performance categories.
