HID to LED conversion: A Smart Upgrade to Save on Energy Costs (2025)[Pros and Cons]

Switching from HID (High-Intensity Discharge) lighting to LED lighting can be a wise move for many businesses, whether you need powerful illumination for parking lots, warehouses, or sports facilities. Yet, with various retrofit options available and the potential upfront costs of conversion, you might wonder: when is the best time to make the switch, and is the investment worthwhile?

LED lighting is widely recognized as an energy-efficient, low-maintenance solution, but each method of conversion has unique advantages and considerations. Here, we explore key questions to help you decide if switching to LED lighting is right for your needs.

Key Considerations When Converting HID to LED Lighting

  1. Energy Savings
    LED lighting offers considerable energy savings over HID lamps. LED lamps operate with lower wattage to produce the same or greater light output, leading to lower energy costs. Calculating long-term savings against the upfront investment will help ensure LED lighting is a cost-effective solution for your facility.
  2. Maintenance Reduction
    HID lighting is often installed in hard-to-reach areas, which may require boom lifts or other equipment for replacements, adding to maintenance costs. LED lamps, by contrast, have a much longer lifespan, meaning fewer replacements and lower maintenance expenses over time.
  3. Consistent Light Quality
    HID lamps can lose brightness and quality quickly, while LED lighting maintains consistent brightness throughout its lifespan. This makes LED lighting ideal for spaces that need steady, high-quality lighting over long periods.

HID to LED Lighting Retrofit Options

If you’re ready to consider an HID to LED upgrade, here are four main retrofit options, each with its pros and cons. Jump to each for specific details. You can click on the name to jump ahead to the pros and cons:

Plug-and-Play (UL Type A)

This is the simplest retrofit solution, allowing you to keep the existing fixture and ballast, requiring only a straightforward swap of the HID lamp with an LED lamp.

  • Pros: Easiest to install with no rewiring needed; generally the most affordable HID-to-LED lighting upgrade option.
  • Cons: Since the existing ballast is retained, compatibility issues can arise, potentially leading to flickering or reduced lamp lifespan. Enclosed fixtures may also cause overheating, creating additional safety concerns.
Ballast Bypass or Direct-Wire (UL Type B)

This method removes or bypasses the ballast entirely, allowing the LED lamp to connect directly to the fixture’s power source.

  • Pros: Eliminates ballast compatibility issues, reducing potential maintenance costs. The energy savings increase, as the ballast is no longer drawing power.
  • Cons: Requires rewiring, which can add installation costs. Fixture design differences may impact the LED light output, though newer LED lamps are often optimized to work around this.
LED Lamp and Driver (UL Type C)

In this approach, the HID ballast is replaced with an LED driver, enabling compatibility with higher-output HID replacements.

  • Pros: Ideal for areas that require high-output lighting. Provides the energy savings and efficiency associated with LED lighting, without the expense of a full fixture replacement.
  • Cons: Installation costs are higher due to the need for a new driver, and this option may require professional installation.

Full Fixture Replacement

Replacing the entire HID fixture with a new LED lighting fixture provides the maximum benefits in terms of energy savings, performance, and longevity.

  • Pros: LED fixtures deliver optimal lighting quality and are designed specifically for your application, ensuring the best illumination. They have the longest lifespans—often up to 100,000 hours—and warranties that ease maintenance concerns.
  • Cons: Higher upfront costs for both materials and installation. However, the long-term savings and reduced maintenance make it a worthwhile investment for many facilities.

Adding Lighting Controls for Greater Efficiency

Pairing LED lighting with lighting controls is an excellent way to further reduce energy consumption. Unlike HID lighting, which can take time to reach full brightness, LED lighting is compatible with responsive controls that allow for immediate adjustments, enhancing energy efficiency.

  • Motion Controls: These sensors detect movement and activate lighting as needed, which is ideal for security or low-traffic areas.
  • Dimming: For settings like retail spaces, dimming controls enable variable light levels to meet different needs while conserving energy.
  • Daylight Harvesting: Adjusts lighting output based on the amount of natural light, further reducing energy costs.
  • Photocell Controls: Automatically turn lighting on at dusk and off at dawn, optimizing energy use.

While controls can increase upfront costs, the long-term energy savings often justify the investment.

Conclusion: Is Upgrading HID Lighting to LED Lighting the Right Choice?

Upgrading from HID to LED lighting is not a one-size-fits-all decision, but it can provide substantial benefits in energy efficiency, lighting quality, and reduced maintenance. For many facilities, the conversion from HID to LED lighting not only lowers operating costs but also enhances overall lighting quality, making it an excellent choice for businesses aiming to improve their lighting systems. By evaluating your specific lighting needs and considering the above options, you can identify the best HID-to-LED lighting retrofit for your facility.
