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 A19, T10, chandelier, etc. Use caution with any type of lamp that is not specified 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 screw-in medium base and candelabra base ‘incandescent’ sockets, as well as GU24 twist-lock ‘fluorescent’ sockets (ie, lampholders). 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.

LED Filament – LED technology has come such a long way that it can emulate the vintage filament-style incandescent lamps of yore. These lamps can be dimmable, wet rated, and come in virtually every incandescent shape from A19 (standard household) to tubular to globe to Edison (ST), etc.

2-Pin & 4-Pin Base LED Plug and Play & Bypass – For fluorescent fixtures requiring replacement bulbs, LEDs can be used with the existing electronic ballast (if still working) – PL Plug and Play – or the ballast can be removed or bypassed – PL Bypass. These are widely available in LED equivalencies from the fluorescent standards wattages from 13 to 42W.

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 120-277V line (ie, universal) voltage.  LED engines offer double the life span over LED bulbs (> 50,000 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, variety of round, rectangular, and linear shapes, and suitability 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) ( who make lamps that are advertised for an approximate life of 20,000 hours.

GU24 Base – GU24 base is also known as Twist-Lock, has a bi-pin connector and is shorter than typical medium base lamps. GU24 is only available in LED and CFL, and is therefore an ideal lampholder for fixtures that may not accept incandescent due to local ordinance.  We offer this lamping for most of our fixtures and recommend using lamps with a correlated color temperature of 2700K for best results.

Self-Ballasted, Compact Fluorescent (CFL) – Self-ballasted, compact fluorescent lamps (CFLs) 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.
