Why the Osram HBI short-arc indium lamp didn't made it to the market? « on: June 19, 2025, 07:08:49 AM » Author: dor123
Before Osram made the HMI short-arc dysprosium lamp, they made an experimental HBI short-arc indium lamp, which had great advantages like no UV radiation.
Why The HBI didn't made it to the entertainment industry, and the dysprosium HMI lamp did this instead?

Because HMI had better colour rendering, efficacy, life, consistency and optical performance

@James: How dysprosium have better CRI, life and optical performance? At the very high pressure of the indium, the spectrum should be a molecular continuous spectrum, with only dips in the blue by the cold indium vapour pressure.

Bad efficiency, particularly due to high leak of energy into useless near-IR I guess...
