Light Biscuit, retail $200.00 (www.inretech.net)
Manufactured by InReTECH (www.inretech.net)
Last updated 03-27-08

The Light Biscuit is an insanely bright "biscuit" - a beefy, squat aluminum cylinder that has nine (9) Luxeon K2 LEDs with collimating optics over each lamp.

It has a rather thick (0.375" (10.0mm)) GE Lexan window ("lens") protecting the LEDs, so it is useful in areas subject to minor to at most moderate vandalism; it should quite easily survive an attack by some wastoid wielding a wooden baseball bat with no damage; an aluminum baseball bat might cause only minor scuffing with the same type of damage to the bat itself.

Colors available are:

Cool-White 4500k (Stocked)

The Light Biscuit is intended to be used on any source of 12 volts DC that can deliver at least 2 amps (2,000mA).

The product comes prepped with 36" (91.40cm) of fairly heavy-guage color-coded wire terminated in polarised (red & black) APP (Anderson Power Pole) connectors.

The Light Biscuit on this web page is a prototype, and will not be available to the general public until 05-01-08.


To use the Light Biscuit, just connect its power cord to any source of 12 volts DC that can deliver at least 2 amps (2,000mA).

The APP connectors are polarised by color: red = (+) positive, black = (-) negative.

Although this prototype unit has no mounting holes, production units will have the following threaded holes:
12x 6-32 holes on the back for self-tapping screws
One Tripod mount

The Light Biscuit is designed to be connected to a source of +12 volts; the power source you choose must be capable of delivering at least 2 amps (2,000mA) on a continuous basis.

Since there are no batteries to fool with, I don't have to tell you which part to remove, throw in the dustbin (garbage can) and then rather emphatically tell you not to.

This is a prototype unit and needs external regulation; that will be provided in production - most likely a "bump in the cord".

Current usage measures 1.81A (1,810mA) on my DMM's 10A scale.
I used the DMM's 10 amp scale to help minimise shunt resistance error.

Photograph of me using only the Light Biscuit for illumination; the camera's speedlight (strobe) was NOT used at all.
Note the sunglasses; I did not feel like frying my poor old eyeballs just for the sake of a photograph.

The Light Biscuit is meant to be used as a fixed light source, not as a flashlight meant to be carried around, thrashed, trashed, and abused; I won't throw it against the wall, stomp on it, try to drown it in the {vulgar term for feces}bowl or the cistern, run over it, swing it against the concrete floor of a patio, bash it open to check it for candiosity, fire it from the cannoņata (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a scanner-type device on a platform with a large readout, with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; and the cannoņata is only used to shoot piņatas to piņata parties away from picturesque Piņata Island), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that I might inflict upon a flashlight.
So this section of the Light Biscuit's web page will be substantially more bare than this section of the web page on a page about a flashlight who's sole purpose in life is to be a flashlight.

Temperature of the hefty aluminum body measures 146°F (63.3°C) after 20 minutes of operation.
I applied a matte-finish adhesive tape to a fairly large section of the light's aluminum body (on its base) prior to reading the temperature to help ensure a more accurate temperature value.

Beam photograph on the test target at 12".
Measures 2,790,000mcd (with an If of 1.81A) on a Meterman LM631 light meter.
This is an artificially low value because the emitting area is much larger than many other lights.

The unit is spec'd (specified) to deliver 2,250 lumens, however I am not equipped to measure light in lumens.
You need an instrument called an "integrating sphere" for that, and I do not own or have access to one.

Distance to target was greater than usual (~5 feet instead of ~3 feet), as the
power cord would not reach the tripod I normally use as a light "firing point".

Test unit was sent by M.B. of InReTECH on 03-08-08, and was received on the afternoon of 03-20-08.
