Advantages
Of Light Fixtures Using Medium Base Incandescent Sockets |
|
|
| The choices of
screw-in LED lamps is rapidly expanding while, at the same time, prices
are becoming more affordable. LED lamps are poised to replace the
venerable incandescent lamps. With
millions of "incandescent" light fixtures in use, the Edision medium
base screw socket (E26) should be around for quite some time.
Incandescent light fixture can utilize by far the widest range of lamp
types, shapes, beam spreads, clear or frosted, wattages,
colors or color temperatures, clear or frosted, etc. for maximum
flexibility whether it be incandecent, CFL, or future LED. |
| Specifying E26 sockets in custom light fixtures While
we are not a big fan of compact fluorescent lamps, if you want to save
energy now, use self-ballasted compact fluorescents now until the right
LED lamp becomes available. | | Lumenelle's "incandescent" fixtures
are optimized to minimize the effects of the different "light centers"
between compact fluorescent lamps incandescent lamps. In addition, they
are also designed to accommodate the additional space requirements due
to the integral ballast. |
| There are
two common types of compact fluorescent lamps - PL type and self-ballasted.
At the present time, Lumenelle prefers Self-Ballasted Compact Fluorescent
Lamps for the reasons shown below. |

|
|
Lamp wattage can
be easily chosen. Readily available lamp wattages range from 4 - 54 watts |

|
Variety of shapes
and styles available as well as decorator styles for when lamp will be
visible. |
|
Difficult to change
lumen output of fixture after installation. |
|
|
Self-ballasted CFLs
all screw into the common medium base socket allowing change of lamp wattage/lumen
output/ color temperature easily whenever desired. |
|
Difficult to accommodate
situations requiring uneven fixture spacing. |
|
|
Self-ballasted CFLs
are available in a wide variety of lamp wattages. Individual fixtures can
easily use different wattages and/or beam patterns to balance the required
lighting. |
|
When a ballast fails
under warranty, the fixture has to be removed and returned. |
|
|
The lamp and ballast
are an integral unit. Every time the lamp is replaced, you get a new ballast. |
|
When a ballast fails
out of warranty, the ballast has to be repaired by a qualified electrician. |
|

The lamp and ballast

|
If the replacement
ballast is not identical to the one as manufactured, the UL listing becomes
void. |

|
Typically, CFL sockets
are plastic. Eventually, many will become heat embrittled. |
|
|
Porcelain socket
will not become brittle with heat and age as plastic sockets may. |
|
Limited retail sources.
Some types are only available from electrical distributors. Home centers
stock only the most popular part numbers. |
|
|
Self-ballasted CFLs
can be purchased almost anywhere that sells incandescent light bulbs. |
| Future LED direct replacement uncertain. (Powering LEDs from a fluorescent ballast is complex.) | | | Future LED replacements for a multitude of incandescent lamp types certain. |
|
|
| Lumenelle also recognizes
that there are applications where PL type compact fluorescent lamps are
required. Lumenelle can also provide light fixtures that use PL type compact
fluorescent lamps. |
