Xtrem Lighting Kit
Deluxe Dual Module Series
This lighting kit is very flexible in how it can be installed in different models and to accomplish realistic lighting that is far brighter
than regular LED kits. The Luxeon LEDs are the key to getting this high visibility and excellent performance. The lighting kit requires a battery to power the LEDs
and some planning is necessary to ensure that your battery has enough power for lighting and any other scale accessories you may be using on your scale model. |

The following is a guides to help give you a better idea of what is still needed to install the lighting kit and how to decide the battery capacity that matches
the lighting configuration you have designed.
Calculating power consumption and battery capacity:
The power consumed depends on the number of LEDs attached to the module. The Luxeon LEDs are very bright and can consume a large amount of power when the solid LEDs are used continuously.
The general formula for capacity: (LED Consumption Rate) x (Number of LEDs) x (Hours of Use). Let's base our examples on providing enough power for 2 hours of continuous use which is usually
sufficient for a day at the flying field.
Each flashing LED consumes an average current of 40mA.
Each solid LED consumes an average current of 200mA.
Example 1. Typical Installation:
2 flashing Red, 2 solid Red/Green navigation & 2 solid White landing lights (intermittent).
2 Flashing LEDs x 40mA = 80mA x 2 (hours of continuous use) = 160mA.
4 Solid LEDs x 200mA = 800mA x 2 (hours of continuous use) = 1600mA.
Total capacity: 1600mA + 160mA = 1760mA. Choose a minimum battery capacity of 2100mA.
Example 2. Full Installation:
5 flashing, 2 solid Red/Green navigation & 2 solid White landing lights (intermittent).
5 Flashing LEDs x 40mA = 200mA x 2 (hours of continuous use) = 400mA.
4 Solid LEDs x 200mA = 800mA x 2 (hours of continuous use) = 1600mA.
Total capacity: 1600mA + 400mA = 2000mA. Choose a minimum battery capacity of 2400mA.
Luxeon LED installation:
The solid LEDs consume a lot of power and generate heat. It is manditory that these solid LEDs which are normally used continuously be installed with a heat sink. This is to ensure
that the LED operates within its normal temperature range. Solid LEDs used without a heat sink will burn out quickly. A little planning is required to install the solid LEDs into the
fuselage. Each solid LED installation must accommodate its heat sink. The simplest method is to mount each solid LED on a small piece of Aluminum sheet measuring 25mm x 15mm x 1mm
or an Aluminum tube measuring Ø5 x 20mm. If an adhesive is to be used, make sure it can withstand a minimum temperature of 100°C [212°F] and improves heat conduction
to the heat sink. Do not mount the bottom surface of the solid LED to the fiberglass fuselage directly, the LED will burn out and you will need buy another LED lead and replace it.
We have seen good performance from a typical installation and no deterioration of the fiberglass when a proper heat sink has been installed flush to the inside of the fuselage first
with the LED on top. Clear lenses have not been a problem when installed over the top of the LED. Flashing LEDs do not require heat sinks.
In all lighting installations, care should be taken to plan the wiring layout inside the fuselage, including all lighting and any scale accessories that will be included. Secure lighting
wires to avoid them from chafing against the fuselage, especially when passing through openings. Several common plastic coverings are available that will insulate the wiring from the inside
of the fuselage and can be removed later if wires need to be added or removed. Similarly, small plastic tabbed clamps can be fixed in several places to the fuselage to hold your wiring
in place.
