OSRAM LED Gas Discharge Lamps

OSRAM LED Gas-Discharge Lamps — LED replacements for HID / HQI systems

LED gas-discharge lamps from OSRAM are designed to replace older high-intensity discharge (HID) and gas-discharge (metal-halide, mercury-vapour, HQL) lamps in large-scale luminaires. They offer reduced energy consumption, lower maintenance, and adaptation to modern driver/gear standards while leveraging existing fixtures.

OSRAM LED Gas-Discharge – Use-cases and practical insights

Gas-discharge lamps (HID types such as metal‐halide, HQL, mercury/vapour) have been widely deployed in warehouses, high bays, street lighting, outdoor canopies and industrial halls. Their drawbacks: high wattage, long warm-up, high maintenance, and declining availability. LED gas-discharge replacements from OSRAM allow you to retrofit existing luminaires (in many cases) or spec new ones with significantly lower OPEX.

Practical situations:

• Replace an existing 250 W HQI lamp in a high bay with an OSRAM LED equivalent designed to provide same lumen output with <100 W.
• Upgrade outdoor floodlighting from 400 W metal-halide + ballast + ignitor to LED module with simplified gear.
• Use in industrial plant areas where maintenance access is costly; longer life LEDs cut intervention cycles

OSRAM LED Gas-Discharge – Key Parameters & Why They Matter

• Wattage reduction: LED replacements often consume ~30-50 % of the original HID wattage. This directly reduces energy cost and cooling load.
• Luminous flux equivalence: You must compare “lumen output” of the LED to the existing HID lamp’s delivered lumens. Some LED replacements publish “replaces 250 W” etc.
• Beam/distribution & CCT/CRI: Many HID lamps have broad beams; LED replacements must match or improve optics and colour temperature to avoid changing visual ambience.
• Driver/gear compatibility: Existing HID luminaires use ballasts, ignitors (for arc start) and controlgear. LED replacements may bypass or replace these. Incorrect driver switching causes failure or flicker.
• Thermal & lifetime: LED modules still generate heat. The fixture’s thermal path must support the new module. Lifetime ratings (e.g., 30-50k h) matter because maintenance access is often expensive in these applications.
• Standards & phasing: Many gas-discharge lamps contain hazardous gases or are being phased out; LED replacements remove those constraints

OSRAM LED Gas-Discharge – Buyer Checklist & Common Mistakes

Checklist:

• Confirm that the replacement LED module matches the delivered lumens of the existing lamp (not just wattage).
• Inspect the existing fixture gear: is there a ballast + ignitor? Will it be bypassed or reused?
• Check thermal condition: ensure the fixture’s temperature limits allow the LED module’s Tc rating.
• Verify optical distribution: if the original lamp had directional or flood optics, ensure the new module matches beam angle or use supplemental optics.
• Plan for maintenance access: one of the main LED benefits is reduced relamp; ensure the driver is accessible for long life.
• For large installations, standardize the LED module across assets to simplify spares

Common mistakes:

• Installing an LED replacement without bypassing the old ballast → extra failures or incompatibility.
• Choosing a lower wattage LED that leads to under-lighting relative to the original HID lm output.
• Ignoring fixture thermal clearance: LED modules are sensitive to heat, so poorer thermal conditions shorten life.
• Failing to update controlgear (dimming/photocell) when the system changes from HID to LED.
