FAQ – Foreverlamp High Bay LED Lighting
- Is the light output of the Foreverlamp LED replacement lamps equivalent to the Metal Halide or High Pressure Sodium lamps it replaces?
Yes. The Foreverlamp LED replacement lamp series will replace 1000W, 400W, 320W, 250W and 175W metal halide (MH) or High pressure sodium (HPS) lamps and deliver the same light levels that the MH or HPS fixtures were originally designed to deliver.
- Will the lamps suffer from lumen depreciation like in the case of metal halide lamps?
An added benefit of the Foreverlamp LED replacement lamp series is that it maintains a much more consistent light output level over its lifetime (50,000) + hours than that of a MH lamp, which suffers from rapid lumen loss.
- Does the Foreverlamp LED replacement lamp require the starter used by the MH lamp?
Pulse-start ballasts have a starter that fires when the ballast sees an open circuit. This starter then shuts off as soon as the lamp starts conducting voltage. The Foreverlamp series conducts voltage immediately upon power being applied so the starter is not used by the Foreverlamp LED replacement lamp series.
- Are the Foreverlamp LED replacement lamp suitable for installation with electronic as well as magnetic ballasts?
No. The Foreverlamp series is only suitable for use with pulse- or probe-start magnetic ballasts, using E39/EX39 mogul base, or in the Foreverlamp fixture with electronic driver.
- Can I connect the Foreverlamp LED replacement lamp directly to a line voltage?
No. The Foreverlamp series cannot be directly connected to line voltage – it receives its power through the installed magnetic ballast.
- Is there a way to identify what kind of ballast (CWA/reactor) is used on an existing fixture?
A method to identify the kind of ballast, is by measuring the ballast’s output open circuit voltage. The CWA ballast’s open circuit voltage is always higher than 280V, usually around 300V, and the Reactor ballast’s open circuit voltage should be the same as line voltage since there is only one coil.
Another way to identify the ballast type is by checking the input cables; the reactor ballast will have 2 wires- the line (120/277) and com, the CWA ballast will have multiple wires- line (120,208,240,277) and the com.
- Is the Foreverlamp LED replacement lamp series damp rated?
- What is the temperature range in which I can use the Foreverlamp LED replacement lamps?
The Foreverlamp series can be used in a temperature range of -20C to +55C.
- Can the Foreverlamp LED replacement lamp be installed in lensed or enclosed fixtures?
No. The Foreverlamp series must only be installed in an open fixture with air flow.
- Can the Foreverlamp LED replacement lamp be used in environment containing dust, dirt, chemical solvents etc.?
No. The Foreverlamp series must only be installed in such environments.
- Foreverlamp Certifications and Testing?
The Foreverlamp is UL listed and UL recognized. Foreverlamp maintains appropriate LM80, LM79, ISTMT, and TM21 laboratory testing results, available upon request.
- Will the Foreverlamp LED replacement lamp extend the life of my installed ballast?
The Foreverlamp LED replacement lamps require much less work from the installed ballast than the metal halide lamps they replace, so the ballast operates at a much cooler temperature. Initial examination indicates that installation of the Foreverlamp LED replacement lamp may actually extend the life of the ballast by 2-3X. The starter which is the most common component to fail in a metal halide system is not needed to operate the LED replacement lamps. Therefore, a defective starter will have no effect on the operation of the lamps
- What happens if the ballast fails?
If the installed ballast fails, it would need to be replaced to continue to operate the Foreverlamp LED replacement lamps.
- What LED chips are used in the Foreverlamp LED replacement lamp?
Nichia, a world leader in LED chip design and manufacturing makes the LEDs used within the Foreverlamp LED replacement lamps.
- Will the Foreverlamp LED replacement lamps and fixtures qualify for any rebates?
Yes, please contact your local utility provider directly for further details on incentives available in your marketplace. Some utilities provide direct rebates and other custom rebates.

- Foreverlamp LED lamps are functionally dependent on the ballast/capacitor
The ballast and capacitor can be considered as a part of the circuit. However, when an ignitor exists, that is not part of the circuit and is not needed. In fact, if the ignitor goes bad it has no impact on the lamp operation.
- Is the Foreverlamp LED light output dependent on the condition of the ballast/capacitor like a standard HID lamp?
Yes, the LED’s light output is a linear relationship to its driving current, so, if the capacitor somehow causes lower current, the LED lamp derates accordingly.
- Will the Foreverlamp LED lamp be damaged, reducing its useful life by running a worn/crystallized capacitor?
When the capacitor short circuits, the output current from ballast is about max 9-10Amp, Foreverlamp’ s LED MCPCB heats up rapidly, and triggers the thermal-protection in the lamp in less than 10mins. The thermal protection will cycle the lamps off until the short circuit is cleared. There is no damage to the lamp when this occurs. This isn’t a common issue with dry type capacitors, more of an issue with oil filled.
- Do you recommend replacing ballasts before installing Foreverlamp LED lamps? Not needed. As a trouble shooting step check the line voltage at each fixture to account for voltage fluctuation (under or over nominal). If everything is normal nothing more is done, if not, the issue is dissected (typical would be ballast, capacitor, or socket) and fixed then.
Also, very rarely is the ballast (core and coil) bad, it is most common that the capacitor has expired.
