Overview

The Ushio BC8945 is a 30-watt incandescent light bulb designed specifically for healthcare, medical, and scientific equipment. It features a clear glass envelope that allows the full, unfiltered output of the filament to reach the target area — a critical requirement in instruments where light quality, color temperature, and consistency directly affect diagnostic accuracy or experimental results. The BA15d double contact bayonet base locks securely into compatible sockets, resisting loosening from vibration or repeated equipment handling.

Rated for 115/125 volts, the BC8945 operates on standard North American line voltage commonly supplied to medical and laboratory equipment. As an incandescent bulb, it provides instant-on illumination with no warm-up period and delivers a continuous spectrum of light, characteristics that some medical applications require over LED or fluorescent alternatives. Users should keep replacement units on hand, as incandescent filaments have a limited operational lifespan and this specialty bulb may not be readily available at general retail outlets.

Pros & Cons

👍 Pros

  • Clear finish delivers unobstructed light output for precision-critical medical and scientific instruments
  • BA15d double contact bayonet base provides a secure, vibration-resistant connection in equipment
  • 30W rating offers adequate illumination while keeping heat output manageable
  • 115/125V range accommodates standard North American voltage without a transformer

👎 Cons

  • Incandescent technology is less energy-efficient than LED alternatives
  • Finite filament life means periodic replacement is necessary in high-use equipment
  • Specialty BA15d base limits availability compared to common household bulb types
  • Generates heat during operation, which may be a consideration in enclosed or heat-sensitive equipment

Frequently Asked Questions

The BC8945 uses a BA15d double contact bayonet base, which is a standard fitting found in many medical and scientific instruments. Verify your equipment's socket type before ordering.
The bulb is rated at 30 watts with a voltage range of 115/125 volts, making it compatible with standard North American line voltage in medical and laboratory equipment.
The clear finish provides unfiltered, direct light output without the diffusion that frosted bulbs introduce. This is important in medical and scientific applications where precise, unobstructed illumination is required.
This bulb is engineered for healthcare, medical, and scientific equipment. While it may physically fit some household fixtures with a BA15d socket, it is purpose-built for specialized applications and is not intended for general residential use.
Bulb lifespan depends on operating conditions and duty cycles within the specific equipment. As an incandescent bulb, it has a finite filament life and is considered a consumable replacement part.
