Shown
to the right of this paragraph is a comparison diagram of our small
light
bulbs as they related to one another and a reference coin. Shown
in the chart below are photos of each of the miniature bulbs we
currently
carry followed by a chart listing all of the bulbs currently available
from RailTronics. These bulbs are great for various
lighting purposes on your layout including your structures, number
boards
in your (N scale) locomotives (use the .75 mm Ultra Small bulb),
passenger
coach lighting and many other uses. Since these small bulbs
operate
with 1.5 VDC they start operating almost right away! The Super
Micro
Bulbs are also available in the colours Amber, Green and Red which will
allow you to use them in many more places on your
layout.
Refer to the notes below for how to hook
these
light bulbs up using a resistor (click here to see our resistor
selection)
to prevent destruction. You can also use these bulbs with diode
(click
here to see our diode selection) based constant lighting circuits.

The 1.5 VDC bulbs
should
only be hooked up to a single 1.5V battery (ie. AA, AAA, C or D) or to
a 1.5VDC supply (available separately). Please note these are DC
voltages, do not connect these bulbs to AC voltage.
If you wish to use a higher voltage supply you must connect the lamp via a series resistor or it will be instantly destroyed. For example using a 12V supply a 700 ohm 1/4 W or higher resistor is required. For 16V supply a minimum 1k ohm 1/4 W resistor should be used. A diagram is provided below which illustrates these two examples. If you wish you can also obtain resistors from RailTronics, click here for more information. Alternatively you can also place bulbs in series however if one fails it's that old Christmas tree problem, which bulb is dead? If you have any questions please call us or send an e-mail.

Shown below are a number of lighting kits which will find application
on
your model railroads in many places. These kits use the miniature
light bulbs shown above and add a few extra parts to make them into a
complete
lighting system which just requires your assembly and installation on
your
layout or in your structures.

Shade Lamp - This lamp is
typical
of outdoor/security lamps found on all types of buildings. You
will
also find application for this lamp as a hanging ceiling lamp in many
industrial
structures, garages and sheds. The lamp is constructed of stamped
brass and pained "Industrial Green" on the outside and "Reflector
White"
on the inside. Equipped with a 1.5V clear micro bulb (see E-LmCSM
above). The diameter of the lamp is 5/16". For use in all
scales
HO and larger. You have probably seen these bulbs used in many
magazine
articles and in NMRA contest models!

| Same as below without brass tube | Frosted Globe Lamp - This
lamp is
a frosted globe of 6 mm diameter with a 1.5V clear micro bulb (see
E-LmCSM
above) installed. You can use this lamp in scales from HO through
to
S. In HO the globe size is roughly equivalent to an 18" globe.

Frosted Globe Streetlight Kit
- This
kit comes with a 1.5V clear micro bulb (see E-LmCSM above), a 1.5"L x
1/16"
diameter brass tube, a drilled 6 mm frosted Globe Lamp (as above) and
instructions.
Simply glue the bulb into the globe, run the wires through the brass
tube,
place on your layout and connect to 1.5V supply. Use on all
scales
HO through S.

Oldtyme Gas Streetlight Kit
- This
kit consists of a clear 1.5V micro bulb (see E-LmCSM above), a 1.5"L x
1/16" diameter brass tube, a tapered transparent lens, a plastic cap
and
instructions. Install in the same manner as described above
(Globe
Streetlight Kit). The lens, with black cap measures 3/8" high and
3/16" square at the top. Use on all scales HO through S.
