OPUS LED Capsules

Capsule bulbs are ideal for times when you need a high-intensity bulb in a small space. Most capsule bulbs are halogen, and with a ban on many halogen bulbs due to take effect this September, it may be time to consider upgrading your current capsule bulbs to a more efficient LED lamp. Our new OPUS LED capsules are made of glass like traditional halogen capsules, but they require approximately 90% less energy to power.

OPUS LED capsules are ideal for both residential and commercial use:

  • Residential: Ceiling lights, desk lamps, side table lamps, pendants, cabinet lighting, and accent lighting.
  • Commercial: Medical, stage, studio, and other specialty equipment, as well as decorative light fixtures.
