  • This lamp is intended for use in open luminaires (fixtures) ONLY.
  • Recommended for use with 50-60Hz AC magnetic transformers or regulated DC power supplies/drivers only. Not recommended for use with high-frequency electronic AC transformers, as this usage will either create non-functional lighting, or if functionality occurs initially then internal MR16 LED bulb damage may result in premature product failures. Use of high-frequency transformers will void the warranty.
  • These models are for use with standard ON/OFF switches only, not with a dimmer. Use with any type of dimmer, relay or other current/voltage control circuit device will void warranty.
