FLEX TEK 12V LED LAMP

Flex Tek 12V LED Lamp, retail $TBA (www.flextek.de...)

Last updated 02-19-09




The Flex Tek 12 volt LED Lamp is just that: an LED lamp that can be operated from any convenient source of 12 volts DC. Although this is mainly intended to be used in vehicles like cars, trucks, vans, SUVs, RVs, camping trailers, etc.; this light can also be used to illuminate museum exhibits thanks to its total lack of UV radiation (see the spectral chart farther down this web page for proof of that).

It features 8 warm-white 3mm LEDs in a CNC-machined aluminum housing, prepped with approximately 40" (~100cm) of color-coded wires to supply power to the device.


SIZE



To use this light, find a place you wish to mount it, and fasten it to that surface with the included wood screw. The top of this screw is a #10 Torx head; here is a photograph of it so you can find & use the correct tool:



Connect it to a source of 12 volts DC: solid red wire to (+) positive and the wire with the black stripe to (-) negative.

If you desire an on/off switch, you'll have to procure it elsewhere and install it in the circuit yourself. The switch should be wired in series: between the (+) positive lead of the fixture itself and the (+) positive of the power source.



Since this product uses any source of 12 volts DC (such as from a vehicle, trailer, or boat battery) or AC adapter that can furnish at least 100mA at 12 volts DC, this section is really not necessary.

Current consumption measures 87.9mA on my DMM's 400mA scale.



The light output by this product is in the form of a medium flood; with an approximate viewing angle of 50°. The color appears to be a warm, distinctly yellowish-white.

This appears to be a very durable product; it is made from CNC-machined aluminum. With permission of the manufacturer, I administered that terrible "Smack Test" on it; ten whacks against the corner of a concrete stair, and I found the expected damage: some light gouging in the bare aluminum where it was struck; no optical or electrical malfunctions were detected.

I normally don't perform "The Toilet Test" on products that are meant to be mounted somewhere and then not {vulgar term for having had intercourse} with, but I was given explicit written consent (not implied oral consent) to do that test, so here goes...BRB...ok, after letting it sit submerged for two minutes in the cistern (toilet tank) at a water temperature of 47°F (9.4°C) and a depth of ~12" (~30cm), I douched it off under the faucet to flush away any chlorine from the in-tank bowl cleaner, dried it off as best as I could with some bungwipe, and no malfunctions were detected.

Although it is *NOT* rated to be submersible, it is water-resistant enough that occasional splashes of the wet stuff won't damage it.

This lamp is suitable for use with alternators.

The lamp is available in two colors: a pleasant warm-white for general illumination purposes, and in red for night time chart/map/table illumination.

The English version of this product's web page is, in my opinion, clear and easy to understand.

Remember, wider viewing angles always, ALWAYS, ALWAYS equal lower mcd values.

These spectrographic charts prove beyond a shadow of a doubt that there is no UV radiation (generally defined as radiation below 395 or 400nm) in the light generated by this product. So it is OK to use it for lighting museum installations.


TEST NOTES:
Test unit was sent by Flex Tek on 03-24-06, and was received on 03-30-06.

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