Easy Understanding of Light Bulb Measures

 


Have you ever ordered a light bulb only to discover it doesn't fit inside your fixture?

Have you upgraded to LED and discovered nothing fits at all? 


If you're looking for any type of alternative to the bulb currently being used, there are many considerations to properly sizing a light bulb.  RealLighting has easy tips to help you manage the rounds and abouts of light bulbs. 

When looking at the measurements of a light bulb, the standard terms in the lighting industry refer to these measurements:


Maximum Overall Length in Inches = MOL

For MOL, you want to measure from the tip of the base to the top of the bulb, including any reflector.

 


Distance From the Light Center = LCL

This is not half the distance of the MOL!  This is looking at where the luminaire is inside the glass and measuring from that halfway point to the bottom of the base.

 


Maximum Overall Diameter = Dia

This looks at the diameter from widest point to widest point.  You are not measuring the circumference of the bulb.  Just a single side.

 

If you do not possess the original bulb number, having the above identified numbers will assist the staff at RealLighting in providing you with the appropriate bulb.  It's also important to know the wattage, color temperature and voltage.

The MOL, LCL, and Dia are even more important when you’re upgrading to an LED product from a standard incandescent, halogen, metal halide, etc. bulb.  In most cases, LED bulbs are larger than their standard light bulb equivalents.  This is especially true with Corn Cob (LED replacement to Metal Halide/High Pressure Sodium).

If you’re considering upgrading to LED bulbs, read more about preparing your job site for LED upgrades, or contact RealLighting today for professional and knowledgeable assistance on getting the right LED bulbs for your interior or exterior spaces.
