Two Hills Studio offers a variety of metal finishes, glasses, micas and acrylics for use in our lighting and other decorative metal work.
Labeling – Lamps (bulbs) are not provided with our fixtures. Each fixture is labeled with the maximum wattage allowed. In some cases the exact type of lamp is specified such as A-19, A-15, candelabra-base, etc. Do not attempt to use any type of lamp that is not recommended and do not exceed the maximum wattage. Failure to do so may result in a risk of fire.
LED – Light Emitting Diode Lamps using LED technology have come along way since entering the consumer marketplace and offer extremely long life with very low energy usage and can be used in standard medium-base and candelabra-base ‘incandescent’ lampholders (ie sockets). Most of our light fixtures are specified for use with LED bulbs. LED bulbs are not all alike, especially when it comes to dimming. If you require dimming bulbs, be sure to check the manufacturer’s or vendor’s dimming compatibilities.
Integral LED – Integral LED engines, also known as retrofits, forgo a traditional ‘bulb and socket’ for a self-contained lamp comprised of LED chips on a board with an integrated driver powered by 120V or 277V line (ie, universal) voltage. LED engines offer double the life span over LED bulbs (> 54,000 hours), a variety of power/wattages and lumen options, great energy efficiency, and standard TRIAC/ELV dimming. They also offer considerable design flexibility with their slim profiles and also suitable for fully enclosed fixtures.
Incandescent – One of our trademarks is the dramatic light patterns that our fixtures provide. For incandescent fixtures with punching or open notches for light patterns, we recommend the use of clear lamps (not frosted) for the best results. For longest lamp life, we recommend using lamps rated at 130 volt which are often advertised to provide approximately 5000 hours of life. There are also lamp manufacturers such as Litetronics International, Inc. (708-389-8000) (www.litetronics.com) who make lamps that are advertised for an approximate life of 20,000 hours.
Self-Ballasted, Compact Fluorescent – Self-ballasted, compact fluorescent lamps can also be used in our fixtures that are wired with standard medium-base or candelabra-base lampholders. We recommend using lamps with a correlated color temperature of 2700K for best results. Please note that, while very efficient, these types of lamps do not produce the sparkle or crisp light patterns in our fixtures with hand-punched holes or open notches on the sides.
GU24-Base Compact Fluorescent – We offer this lamping in most of our fixtures and recommend using lamps with a correlated color temperature of 2700K for best results.
4-Pin Base Compact Fluorescent – For fluorescent fixtures requiring the ballast to be a part of the fixture, we use only electronic ballasts, which require 4-pin lamps. These may include a separate ballast inside the fixture or a GU24-base ballasted lampholder. Most compact fluorescent lamps have an advertised life of approximately 10,000 hours. Only use lamps with wattage matching the labeling on the fixture. Note that on fixtures which have two lamps powered by one ballast, both lamps must be operational for either to work. If one lamp fails, the other will not function. We recommend using lamps with a correlated color temperature of 2700K for best results.
