  Introduction:
TerraLUX TLE-20 new generation Nichia Regel warm white LED based MiniMag AA and MiniMag AAA bulb replacement module. TerraLUX TLE-20 has relatively higher light output as compared to original filament bulb. Nichia Regel LED due to it's warm tint closely matches the color rendering quality of incandescent bulb, yet offers a whiter beam of light. For the same type of batteries TerraLUX TLE-20 will run considerably longer than the incandescent bulb in both types of MiniMag Lights. As the LED replacement is a solid state device, there is no filament to burn out or no glass to break. This makes your beloved MiniMag AA or MiniMag AAA sturdier and last longer without worrying for replacement bulb. Over the period of operation, the incandescent bulb will turn dark due to deposition of tungsten on inner walls of glass bulb in comparison the Nichia Regel warm white LED will remain in good condition for considerably long duration. The Nichia Regel LED operates at higher voltage than original incandescent bulb. For this purpose, Terralux has employed regulated step up electronic circuitry to drive the LED. TerraLUX TLE-20 package includes two custom reflectors, one for MiniMag AA and another for MiniMag AAA. The replacement of incandescent bulb is a simple two step process which involves replacing original reflector with custom reflector and replacing the incandescent bulb with LED replacement. TerraLUX TLE-20 module has gold plated contact pins for better connectivity.

TerraLUX TLE-20 Nichia Regel LED: Here is a closeup picture of the module. The Nichia Regel warm white LED is placed perfectly in center directly. Plastic enclosure encapsulates entire circuitry and protects the inner contents. As the LED is relatively low power consuming device, the need of active heat sinking is not required.

Installing TerraLUX TLE-20 Nichia Regel LED on MiniMag AA: On the back side of packaging instructions to install the LED module are available. Here is the picture for your easy reference.
TerraLUX TLE-20 Nichia Regel LED Instructions

Installation is very simple process. Please note that we have used MiniMag AA flashlight to demonstrate the LED replacement. Same instructions apply to MiniMag AAA LED replacement. So, with the instructions as above, let's begin installing the TerraLUX TLE-20 Nichia LED Replacement. Picture here shows dissembled view of MiniMag 2AA. Open up the head and the bezel as shown below, replace the old reflector with the custom reflector from TerraLUX, reassemble bezel ring back. Next step is to install the TerraLUX TLE-20 Nichia Regel LED Light Module. This is even simpler step. Just remove the old bi-pin incandescent bulb by pulling it out and replace it with the new LED replacement module.

If it does not light up, remove, rotate by 180 degree to reverse the direction of pins and re install. There, you see light. You might have noticed that the light corona is very pleasant warm in color as against the surrounding.
Caution: Do not look/stare at LED directly! It's extremely bright and may cause temporary or permanent eye damage.

Beam Shots:
The beam from TerraLUX TLE-20's Nichia Regel has definite hotspot with soft edges forming corona. The side spill is also relatively bright. Overall, the beam quality is excellent good. Under extreme wide focus mode the beam develops inevitable donut shape, however for medium wide focus the beam is very acceptable. In fact, the beam of TerraLUX TLE-20 LED Replacement is the best of the other LED replacements available from TerraLUX. The Beam shot Matrix shows TerraLUX TLE-20 installed on MiniMag 2AA flashlight with Alkaline and Sanyo Eneloop NiMH Rechargeable batteries. All beam shots are taken at f/8 aperture with varying shutter speed.

Utmost care has taken to ensure that the light measurements are accurate. Click here to read more about Gossen Mavolux 5032 USB Light Meter.

MiniMag AA Alkaline: Before performing runtime test, we first did test for MiniMag 2AA with standard incandescent bulb. As expected, an exponentially dropping light output starting from roughly 6 Lumens out front. The light output for MiniMag AA on standard incandescent bulb reaches 1 Lumen mark in just about 4.5 Hours.

TerraLUX TLE-20*: So how will the TLE-20 perform against standard incandescent bulb? To test this out, we used THE same Alkaline battery as previous test, but after exactly 24 Hours of the test. i.e. we performed Alkaline test on TLE-20 with an highly depleted Alkaline battery. So what are the results? Well, the light output still starts at 10 Lumens and TLE-20 runs for well over 6 Hours 30 Minutes to 50%. The out front light stayed above 5 Lumens for the first 5 Hours on a depleted battery.
