TerraLUX MaxStar5 Module, retail $26.99 (www.ledsupply.com...)
Manufactured by TerraLUX (www.terraluxcorp.com)
Last updated 02-02-07

The MaxStar5 is a ***VERY*** high output retrofit "bulb" designed to be used in a Mag-Lite (3, 4, 5, or 6 C or D cells). It features a new Luxeon V K2 U Bin LED, and it is designed to be used in a flashlight with a metal bulb holder, not a plastic one (see below). The Mag series are perfect candidates for this, because they have metal bulb holders.

Regarding the two photographs above: the first one is of the module itself, and the second is of the finished flashlight.
The flashlight itself was host to an InReTECH Trilight III adapter; that's why it may look so familiar.


This retrofit requires you to have a 3, 4, 5, or 6x C or D cell Mag-Lite.
To install this retrofit, just follow the easy instructions directly below:
  1. Unscrew the head, and set it aside.
  2. Unscrew the collar that holds the light bulb in (as you would for replacing the bulb), and remove the bulb. Do not replace the collar you took off when you removed the old bulb. Throw the collar & bulb in a drawer or somewhere else you can find them in case you ever want to go back to a regular bulb.
  3. Put the MaxStar5 module in the bulb opening, and screw it into the bulb holder (clockwise) until it stops turning.
  4. Screw the head back on.
  5. Do not aim at face. Place on a hard surface. Light fuse and get away.
The beam is adjustable from spot to flood, just like an unmodified Mag-Lite, by turning the bezel (head) clockwise or conterclockwise.
Pressing the rubber button on the barrel turns it on and off.

To change dead batteries, unscrew & remove the tailcap, dump the dead batteries in the nearest garbage can (or the dead battery box, if your community has a battery reclamation program), load the new ones in button (+) end first, then screw the tailcap firmly back on. See, that was easy, wasn't it?

Current measures 545mA on my DMM's 4A scale, when used with 4 D cells.

As a flashlight, the unit is sturdy, and is of a proven physical design. Mag Instruments (of which TerraLUX has *no* affiliation!) has been making flashlights for years, and they have a long track record for durability. This LED module appears that it should live up to those standards, and allow you to get many more useful years out of your Mag Lite.

This LED light bulb replacement in NOT a toy. This product dissipates around 2.5 watts of power which when confined to a small volume will generate high temperatures. This LED light bulb must only be used in a high quality flashlight in which the bulb holder is ALL METAL. Do not use in a flashlight or other appliance made from plastic. Damage to the flashlight, the bulb, and the user will result. We strongly recommend its use in Mag Instruments products as they have the necessary construction features for the high heat output of the MaxStar2. Read the instructions carefully before use. TerraLUX and LED Supply will not be responsible for the damages resulting from improper use and deployment in inferior appliances. Follow the directions included with the product.

The module uses "PowerPush" technology, which is a regulator circuit to help ensure the LED intensity remains stable as the batteries discharge.

The unit can be used as an "electronic candle" by unscrewing & removing the bezel (head) and then standing the light on its tail. The light will lose water-resistance in this mode, so please do not place it directly under the drip in a leaky tent, or you might be rather sorry.

Test unit of this and another TerraLUX product were sent by Z.T. of www.ledsupply.com on 01-29-07, and were received on the afternoon of 02-01-07.

Product was made in the United States. A product's country of origin really does matter to some people, which is why I published it on this web page.
