Dimming
Warranty policy on the dimming of Venture Lighting International metal halide lamps:

SCOPE: Venture Lighting metal halide lamps can only be step or bi-level dimmed by switched reactance methods, including capacitance or inductance changes to the ballast. Line voltage and electronic dimming systems are not covered by this policy.

WARRANTY POLICY: Venture Lighting International, Inc. agrees to extend a limited one-year warranty on lamp life to lamps operated on dimmable control gear, provided the following conditions are met:

1) A lamp must never be started by a ballast operating in the dimmed operating mode.

2) During any lamp start (cold or hot restart), the ballast must meet all of the requirements for starting and sustaining a lamp described in ANSI document C78.13xx for that lamp.

3) The lamp must be allowed to warm up for at least 10 minutes after the lamp has started (20 minutes for lamp wattages greater than 450). Only then can dimming begin.

4) For system design purposes an ANSI reference lamp cannot be dimmed below 50% of the rated lamp wattage at:
a) 90% input voltage for CWA ballasts
b) 95% input voltage for lag ballasts.

5) Operating position requirements are
• Base up ±15°, only, for probe start or pulse start lamps designated as U, BU, HBU
• Vertical ±15°, only, for pulse start lamps designated as U, V
• Base down ±15°, only, for pulse start lamps designated as BD, HBD
• No Horizontal dimming.

6) The ballast input voltage must be kept within the accepted line voltage range for the ballast type (±10% for CWA ballasts and ± 5% for lag ballasts) at all times in dim and full power modes

7) The dimming device should not allow the ballast current crest factor to exceed 1.8.

(CSA). Damage by misuse or abnormal conditions of storage, installation, maintenance or operation, including, but not limited to, excessive temperatures or evidence of partial or complete disassembly beyond normal maintenance or expansion procedure void this warranty in its entirety. The conditions of any tests performed concerning any ballast product claimed to be defective in accordance with the terms of this warranty shall be mutually agreed upon in writing between the original purchaser or first end-user and Venture and Venture may be represented at any such test.

No implied statutory warranty of merchantability or fitness for a particular purpose shall apply beyond the afore-mentioned warranty period. This warranty excludes other warranties, expressed or implied and is the exclusive remedy of the claimant. Venture shall not be liable for any special, indirect or consequential damages. Venture's liability on any claim of any kind, nature or description arising out of, resulting from or concerning any aspect of this warranty agreement or from the product or services furnished hereunder shall not exceed the price of the specific ballast or ballasts which give rise to the claim. For warranty service or repair, the buyer shall prepay all shipping charges to Venture and Venture shall pay shipping charges to return the repaired or replaced item to the buyer. However, the buyer shall pay all shipping charges, duties and taxes for products returned to Venture from a country other than that of the United States of America.

Product replacement/liability limits
The foregoing warranty shall be the sole and exclusive remedy of the purchaser and Venture's sole and exclusive remedy to the purchaser. NO WARRANTY OF FITNESS FOR ANY SPECIFIC OR PARTICULAR PURPOSE IS MADE OR IS TO BE IMPLIED. NO OTHER WARRANTY APPLIES. Venture will not, under any circumstance, whether as a result of breach of contract, warranty tort or otherwise, be liable for any costs or damages, including lost profits or revenues, incidental, special or consequential damages.

Some states or provinces do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. This warranty gives you specific legal rights and you may also have other rights which may vary from state to state and province to province. No distributor, salesperson, dealer, retailer or other representative has the authority to change or modify this warranty, either orally or in writing, in any respect.
