Why Switch from High Pressure Sodium (HPS) to LED?

The transition to LED lighting provides immediate and long-term financial and performance benefits compared to outdated HPS technology. The key advantages of an **HPS to LED conversion** include:

• Massive Energy Savings: LEDs consume **60-75% less power** for equivalent or better light performance, driving down utility costs.
• Extended Lifespan & Reduced Maintenance: Enjoy up to **50,000+ hours** of use (compared to 10,000-24,000 for HPS), virtually eliminating the need for frequent bulb changes.
• Superior Visibility (High CRI): LEDs offer a high Color Rendering Index (CRI) of 70-90, significantly improving safety and visibility compared to HPS's poor 20-30 CRI.
• Instant Operation: LEDs provide **instant full brightness** with no warm-up time, enhancing security and responsiveness.
• Easy Retrofit Installation: Many options are direct **ballast bypass** and feature standard E26 or E39 mogul bases, simplifying the **HPS LED retrofit** process.

HPS Wattage to LED Equivalent Conversion Chart

Use this guide to determine the most effective **LED equivalent wattage** for your existing HPS lamps (50W, 100W, 250W, 400W, 1000W, etc.). Our recommendations focus on achieving optimal visual lumens and maximum **energy efficiency**.

Note: LED lumen output is highly efficient (100-150 lm/W). The conversions factor in the superior visual acuity and light distribution of modern LED lighting.

HPS to LED Conversion Tips & Best Practices

Crucial Steps for a Successful LED Retrofit

Before installing your **LED replacement bulbs**, follow these professional tips to maximize efficiency and longevity:

• **Ballast Bypass is Key:** Always **remove or bypass the existing HPS ballast**. Running the LED directly on line voltage (Ballast Bypass) ensures maximum energy savings and prevents ballast failure issues.
• **Check Fixture Rating:** Ensure your fixture is rated for use with **enclosed LED lamps** if the area is sealed or non-vented.
• **Select Optimal Color Temperature (CCT):** Choose 4000K (neutral white) or 5000K (daylight white) for best visibility and safety. Avoid the traditional orange hue of HPS.
• **Calculate Your ROI:** Use our calculator (link) to determine the exact **Return on Investment (ROI)** based on your regional energy rates and usage hours.
