B-Lite Agro 3K CMH Lamp - 500W - 3100 K

Warm 3100 K Ceramic Metal Halide Light for Indoor Cultivation - 500W

Growers who want a balanced spectrum for vegetative growth and flowering often struggle to find a lamp that renders plant color accurately. The Agro 3K uses a ceramic metal halide arc tube to produce a 3100 K output with a CRI above 90, so you can judge plant health by eye. It is rated at 60000 lumens after 100 hours and 950 µmol/s of photon flux.

This single 500W lamp suits a hobbyist replacing a lamp in one fixture, or a regular indoor grower adding a lamp to a compatible ballast. Commercial growers can order one at a time to test it in their rooms before buying more.

Key Features & Benefits

• 3100 K color temperature — a warm spectrum suited to cultivation lighting.
• CRI above 90 — plant color looks natural, which makes inspection easier.
• 30000-hour rated life — fewer lamp changes over time, measured at a 10-hour start cycle.
• Open or enclosed luminaires — fits a range of fixture designs.
• Quartz glass bulb and PCA arc tube — a ceramic arc tube design built for high-output operation.

Who Should Use B-Lite Agro 3K CMH Lamp

Use it if you run a compatible 500W ballast and want a CMH source for indoor cultivation. Check your ballast type before ordering.

Frequently Asked Questions

Q: What ballast does this lamp need?
A: It works with an ANSI C182/0 or an electronic ballast. Confirm your ballast is rated for 500W CMH before installing.

Q: How should I mount it?
A: The burning position is horizontal. Mount it in that orientation for correct operation.

Q: Does the lamp need a break-in period?
A: The distributor notes a seasoning period of roughly 100 hours. A slight pulsation during that time is common until the lamp settles.

Q: Can I run it 24 hours a day?
A: The distributor warns that double-ended metal halide lamps are not designed for 24-hour operation, which can shorten lamp life. Use a timer to keep a regular light cycle.

Q: What does CRI mean?
A: CRI is the color rendering index. It rates how naturally a light shows colors, and a value above 90 indicates strong color accuracy.

Q: What safety steps apply?
A: Unplug the fixture before installing, and wear eye protection because the lamp emits intense UV. Keep it away from flammable materials and replace it at the end of its rated life.
