There are several kinds of halogens that have a tubular capsule which is sometimes used in other products, but also are a standalone lamp.  That's the case with this lamp and others within this category of single ended halogen.  For most people, this double contact or DC base halogen is often referred to as a push and turn base.  The base isn't like a screw-in base at all, it has smooth size and a couple of nubs at the bottom which hold it in place.  What's nice about this type of lamp is the way it rest securely in the socket with no chance of it falling out.  Among all these, this type may be the widest category and encompasses everything from low wattage bipin lamps to higher wattage bulbs.  Like all halogen bulbs, they are filled with a special gas that actually rebuilds the filament and provides longer average lifespan than normal incandescent bulbs.  These halogen lamps burns about 10 percent brighter, whiter, and hotter than normal incandescent bulbs. 

When trying to identify your DC base halogen, one of the best places to start is at the base of the lamp, the part where it makes it's electrical connection.  All single ended halogen have one of several bases which would be a minican (MC or E11), DC base (double contact bayonet) or Candelabra (E12).  These are the lamps which typically have a higher wattage but some are lower as well.  These voltage is almost always 120 volt or 130 volt for longer life.  If you have flood light fixtures, sometimes these are used because of the the small space and large amount of light they produce.  The places where all these have been used over the past 30 years are typically those applications where a greater beam control is desired and lots of light.  DC base halogen light bulbs are available in wide variety of bulbs and wattages as low as 50 watt all the way up to 1000 watts.  Of course, the lengths in different wattages would also vary slightly.  In our shopping cart, we have them listed with a DC designation such as the following, 75Q/DC, 100Q/DC, 150Q/DC, 250Q/DC and 500Q/DC. 

Like all halogen bulbs, these should not be touched with your skin in any way and sometimes the packaging comes with a foam or paper wrapper to prevent this. If they are touched, the life span of the bulb will be greatly reduced as a result of a reaction of the glass. In case you ever do touch a bulb, wipe it thoroughly with a soft cloth. Bulbs that are covered, like the PAR and some of the MR halogen bulbs, are okay to touch, since you are not touching the actual bulb but a heavy, thick glass that covers the light bulb.
