Ushio PulseStrike 70 W ED17 Metal Halide

The Ushio PulseStrike ED17 metal halide bulb delivers 6000 lumens at 4200K from a 70 W high-intensity discharge source. It fits a standard E26 medium screw base and offers a rated life of 15000 hours. The lamp is designed for commercial and industrial flood lighting as well as stadium and sports facility applications where consistent color performance is required.

PulseStrike arc tube thermals and warm-up

The formed-body arc tube follows the natural arc stream curve to allow higher fill gas pressure, reducing electrode evaporation and wear. This design cuts warm-up time to 2 minutes versus 4 minutes for standard probe-start lamps, a 50 percent reduction. Hot restrike capability improves to 4 minutes compared to 15 minutes, a 75 percent improvement, while maintaining universal burn position.

Upgrade from probe-start metal halide

This lamp replaces standard probe-start metal halide bulbs in existing E26 fixtures where faster cycling and longer lumen maintenance are needed. The jump is worth it for installations that suffer from long warm-up or restrike delays, or where electrode wear shortens service intervals. It is not suited for fixtures requiring a different base type or wattage, or for applications needing instant-on lighting without any warm-up period.

Questions about this item

How do I install the E26 medium screw base MH70/U/MED/40/PS bulb and what step is often missed?

Screw the ED17 bulb into an E26 socket rated for 70 W pulse-start metal halide; the step often missed is verifying the ballast is pulse-start compatible, otherwise the arc will not strike.

What maintenance or replacement will the 70 W PulseStrike lamp need over its 15000 hour life?

No routine maintenance is required; plan to replace the lamp once output drops near the 15000 hour rated life, as electrode evaporation eventually ends the arc.

What limit appears first when the MH70/U/MED/40/PS runs continuously in a flood fixture?

The 4200 K colour stability holds well, but lumen maintenance declines after thousands of hours; the 15000 hour rated life is the first hard limit reached under sustained use.
