For The Builder & Developer

For the past twenty-five years we've built our business on excellence of service to our builders and developers.  Extensive product knowledge is the key to successful value engineering for best savings. 

Our experienced material handlers will expertly organize product for delivery.  We deliver house packed and marked for location.  Chain and wire are installed in proper lengths for quick installations of chain hung fixtures.  We specialize in custom homes, tract housing, and multi-family housing.

...The Interior Designer

Our spacious and newly remodeled showroom and wide variety of high-end to mid-range products make selections convenient and pleasant. 

Our staff can help you with your lighting design and help you find products to harmonize with your design environment. 

Our vast vendor resources combined with our product knowledge will save you time and give you a wider variety of selections within your range of interest.

...The Electrical Contractor

We have a larger, broader variety of quality in inventory than warehouse stores, or electrical wholesalers because lighting is our only business. 

Our staff can help you with design and build projects, or energy saving retrofit projects.  We can assemble chain hung fixtures with specific lengths of chain & wire for fast installation. 

Our larger projects give us buying power and keep our prices competitive.  

...The Homeowner

Our showroom is a great place to get new ideas and our experienced and friendly staff can help you with your selections and assist you with your lighting design ideas. We have an impressive inventory for most budgets. 

Our large projects leave us with many quality fixtures we sell at close-out prices.  We also have beautiful discontinued show pieces offered at substantial savings.
