• Power output: 70W
• Base type: RX7s
• Color temperature: 4200K
• Color rendering index: 90-100
• Dimensions: 22mm x 119.63mm

How to use

Installation should be performed by a qualified professional to ensure compatibility with the existing lighting system. The lamp must be inserted into a compatible RX7s socket within a fixture designed for metal halide lamps. Ensure the power is disconnected before handling the lamp. Because this lamp requires a ballast, verify that the ballast specifications match the lamp requirements to prevent damage or failure. Avoid touching the glass bulb with bare hands, as oils from the skin can cause hot spots and reduce the lifespan of the lamp.

What to consider before purchase

• Verify that your existing fixture is compatible with the RX7s base.
• Ensure your lighting system includes the necessary ballast for metal halide operation.
• Confirm that the 4200K color temperature meets your specific lighting requirements.
• Check the physical dimensions of your fixture to ensure the 119.63mm length fits correctly.

Usage recommendations

For optimal performance and safety, always operate this lamp in a fully enclosed luminaire equipped with a protective glass cover. This prevents potential damage in the event of a lamp failure and ensures the lamp operates at the correct temperature.
