Lampholder search

January 8, 2015

New on is the ability to use a search breakdown to find the lampholder you need, tired of going to a website or catalog that has a category called “fluorescent lampholder” just to find 300 units with no grouping?! Now on Semperlite you can search based on the following categories:

1. Lamp base

2. Mounting style

3. Lamp axis

4. Overall height range

5. Shunted or unshunted

6. Wiring method

Just use this link

Also please keep checking back, as we are now working on adding additional categories like, what write gauge they will accept, what wattage range, voltage range etc.


Anthony refrigeration ballasts discontinued

January 8, 2015

Recently Anthony International has started shipping out Fulham brand ballasts even though they ate giving you a part number like “60-76678-0003”. Be aware that if you have an anthony ballat that needs to be replaced try and avoid a anthony they ate in business to sell freezer doors, not ballasts or lampholders.

BC Lighting makes 3 ballasts that will replace any a Anthony ballat you may have and the price will be at a huge discount when compared to anthony.

Shunted vs. Unshunted Lampholders

March 12, 2010

Shunted Lampholders – will have 2 holes (or accept 2 wires) on the unit.

Unshunted Lampholders – will have 4 holes (or accept a total of 4 wires) on the unit.

Shunted Lampholders are to be used with Instant Start Ballasts, and Unshunted Lampholders are to be used with Rapid Start Ballasts.  An unshunted lampholder may be converted to a shunted lampholder by taking a short wire and stripping both ends. Next take one end of the wire and insert it into one hole on the left side of the lampholder, taking the other end and stick it into one of the holes on the right side of the unit.  Thus, making a jump from one side to the other, and now it becomes a shunted lampholder.

Please go to and search for your shunted or unshunted lampholder.
