Product Description
High-intensity 100W short-arc mercury illumination for fluorescence microscopy, UV curing, and laboratory optics.
SOSCleanroom
Overview

The Osram / Sylvania HBO 100W/2 is a high-pressure short-arc mercury discharge lamp engineered to deliver extremely high radiance from a compact arc, producing strong output across the UV and visible range. This “point-source” behavior makes it a trusted workhorse for fluorescence microscopy, UV curing, and laboratory/analytical illumination systems that depend on repeatable optical coupling. SKU: HBO100W/2 (69217).

Key Highlights
  • Power: 100W (nominal)
  • Electrical: DC operation; lamp current 4.3–5.6A
  • Nominal system voltage: 20V class (typical operating design point)
  • Output: nominal luminous flux 2200 lm; multi-line spectrum (UV + visible)
  • Optical geometry: Light Center Length (LCL) 43.0mm
  • Bases / polarity: SFa9-2 (anode) / SFa7.5-2 (cathode)
  • Dimensions: 90.0mm length; 10.0mm diameter
  • Burning position: s90 (anode underneath)
  • Average life: 200 hours
  • UPC: 4050300507095
Typical Applications
  • Fluorescence microscopy and UV-enabled imaging
  • UV curing and photopolymer processes
  • Laboratory & analytical instruments, fiber illumination, and solar simulation
Handling & Safety Tip 
Short-arc mercury lamps produce intense UV radiation and operate at high internal pressure (when hot). Operate only in a purpose-built enclosed housing with proper shielding/interlocks. Allow full cool-down before handling. During installation, use clean nitrile gloves and a lint-free wipe to keep the lamp envelope and bases free of oils and debris.
Industry Update:
In July 2025, ams OSRAM announced an agreement to sell its Entertainment & Industry Lamps (ENI) business to Ushio, with closing expected by the end of March 2026. During and after a transition, customers may see changes in branding, labeling, packaging, and distribution. Best practice: qualify replacements by the manufacturer code and critical specs (HBO 100W/2, 69217, DC, bases/polarity, LCL 43mm, and s90 orientation) to ensure continuity.

Engineering Deep Dive: How Short-Arc Mercury Lamps Produce Usable UV/Visible Light
1) It’s a plasma point-source, not a filament. Inside the quartz burner are two closely spaced electrodes. When a high-voltage ignition pulse initiates conduction, an electric arc forms and a plasma column is sustained between the electrodes. Because the arc gap is very small (“short-arc”), a large fraction of the electrical power is concentrated into a tiny volume—creating extremely high radiance and near point-source behavior. Optical systems can efficiently collect and focus that light with reflectors and condenser optics.
2) Warm-up is a controlled pressure transition. At rest, mercury exists partly as liquid droplets. During run-up, the arc heats the burner, mercury vaporizes, and internal pressure rises dramatically. Higher pressure changes the discharge characteristics and stabilizes the lamp into its designed operating regime. This is why arc lamps require the correct ballast/driver and igniter matched to lamp type and power.
3) “Multi-line spectrum” is the practical advantage. Mercury plasmas emit discrete spectral lines in the UV and visible. In fluorescence microscopy and UV-enabled instruments, filter sets and dichroics are often selected around strong mercury lines (commonly referenced excitation bands include 365, 405, 436, 546, and ~579 nm), enabling high excitation efficiency where those lines align with the chemistry or fluorophore.
4) DC polarity + burning position control stability and lifetime. This model is specified for DC operation and uses different bases for anode vs cathode. DC systems can provide strong arc stability and predictable electrode wear—but only when installed correctly in the specified s90 orientation (anode underneath). Incorrect polarity/orientation can accelerate electrode erosion, destabilize the arc, and shorten life.
System Integration: What Actually Determines Performance in the Instrument
  • LCL (43.0 mm) is a primary fit constraint: housings/reflectors are designed around where the arc sits in space; shifting LCL reduces coupling efficiency and uniformity.
  • Arc stability shows up at the image plane: arc wander can present as flicker or intensity modulation in microscopy/inspection.
  • UV/heat management optics matter: most systems rely on filtering and heat rejection to protect downstream optics and deliver the correct spectral bands.
  • Cooling is part of the electrical design: airflow and housing temperature influence arc stability, pressure, and service life—treat cooling as a requirement, not an option.
  • Hot restart is limited by pressure: after shutdown, internal pressure can remain too high for immediate re-ignition; many systems require a cool-down interval before restart.
Safety & Handling (Non-Negotiables)
  • Enclosed housing only: high luminance, UV radiation, and high internal pressure (when hot) require operation only in purpose-built enclosed lamp casings.
  • Mercury hazard: if the lamp breaks, mercury can be released—follow facility spill response and disposal procedures.
  • Allow full cool-down: never handle a hot lamp; avoid shock, vibration, and rapid cooling.
  • Control UV exposure: maintain shielding, interlocks, and appropriate PPE for any service event.
Industry Update: ENI Business Transition (Closing Expected End of March 2026)
Keep the manufacturer ordering code (HBO 100W/2, 69217) in your maintenance records and qualify alternatives by DC electrical requirements, bases/polarity, LCL, and burning position to protect optical performance and service continuity.
Cleanroom Considerations (Best Practice)
  • Service like a controlled maintenance event: stage clean nitrile gloves, a cleanroom-grade lint-free wiper, and a compatible swab for socket/contact cleaning.
  • Minimize debris: keep packaging fragments out of housings; remove any loose fibers/particles before re-energizing the system.
  • Protect reflectors and UV optics: avoid touching optical surfaces; use low-lint technique to prevent haze and particulate deposition.
  • Recommended consumables: cleanroom-grade lint-free wipers and swabs (Texwipe options are commonly used in controlled environments) help reduce residue and particulate risk during lamp changes.
