JTSPOTLIGHT FOR 12 VOLTS

JTSpotlight for 12 Volts, retail $14.95 (http://www.jtspotlight.com...)
Manufactured by Weiugo Solutions, Ltd. (12v Spotlight)
Last updated 01-10-10




This is a small, rather bright LED flashlight with a little twist: it is specifically designed to be recharged by plugging it into the female cigerette lighter receptacle (sometimes called an "accessory jack") in automobiles using a standard +12 volts negative ground electrical system.

It comes in a mostly metal body (the end window and the insulating washer are the only two nonmetal components readily visible on it), it produces light with a 0.5 watt white LED (a model # W92050C Seoul Semiconductor Z-power LED) and an acrylic TIR optic, and it is powered by a NiMH battery safely tucked away inside.

A red LED comes on (located behind the optic where it can readily be seen but is not obnoxious) whenever the product is charging.


SIZE



To use this flashlight, first unplug it from your auto's cigerette lighter receptacle, and give the bezel (head) approximately 1/7th of a turn clockwise (as though tightening it).

To turn it off, give the bezel approximately 1/7th of a turn counterclockwise (as though loosening it).



There are no disposable batteries to deal with in this product, so I don't have to tell you which part to remove, flush away, and then tell you not to.

Just plug it into your automobile's female "siggeret" "lyter" receptacle. Charging is indicated by the front-end of the light glowing red.


This photograph shows the red "charge engaged" LED behind the optic assembly.
It's obvious, but not at all obnoxious.

The only thing in the instructional material regarding charging is to be certain the bezel (head) is firmly set to the "off" (or "chrg" as it's marked) position; the product apparently does not charge while it's on.

There is no indication of how long the product should charge - either from a partial discharge or a full discharge. It is said that the product requires 7 hours for a complete charge cycle (from a fully discharged battery to full charge).

The instructional material states that this product might not fit *ALL* lighter sockets; an adapter (that includes two female cigerette lighter receptacles) is available if necessary.



This flashlight appears to be reasonably durable, and it is. When I performed that terrible smack test on it (ten whacks against the concrete floor of a patio: 5 smacks against the side of the bezel and 5 smacks against the side of the tailcap), only some rather minor damage was found. There is some extremely minor gouging to the bare Metalguilmon - er - the bare Metalcalmarimon - um that's not it either...the bare Metalparrotmon...er...uh...wait a sec here...THE BARE METAL (guess I've been watching too much Digimon again! Now I'm just making {vulgar term for poop} up!!! ) on the side of the bezel where it was struck.

No optical or electrical malfunctions were detected.

This flashlight is splash- and water-resistant at very minimum; and though it almost passed "The Suction Test", it did not actually *PASS*. Some leakage was detected from the tail end (where it plugs into the "siggeret" "lyter" receptacle), but this leak is minor.
So, splash- and water-resistant, yes.
Submersible, no.
The packaging claims "submersible", but I think this is a bit of horse puckey. :-/

The packaging also states that the product is RoHS-compliant, which simply means that there are no substances that would be toxic to the environment (such as cadmium, lead, mercury, or other heavy metals) when the product ends up in the landfill - which will very likely be a rather long time.

This is quite a high value for such a small instrument.

TEST NOTES:
Test unit was purchased on the 12v Spotlight website on 02-25-08 and was received on the afternoon of 02-27-08.


UPDATE: 04-24-08
I have heard from the manufacturer that this product is IPX7 certified (underwater 3 feet for 30 min), so the leakage in my particular unit is (according to them anyway) just a fluke. So I'll repeat "The Suction Test" on it and return it to their US warehouse if leakage is still detected...BBS...ok, leakage was still detected, so I'll be sending this unit back shortly.

Best guess here is that there is supposed to be an O-ring between the bezel and barrel, and that somebody forgot to install it on this particular unit; as the bezel has a kind of "rough" feel when using it to turn the product on & off.


UPDATE: 04-24-08
No, you aren't seeing things.
Yes, a same-day update.
I've been given the address I should send my defective unit to; it'll be boxed up (if I can find a suitable shipping container!) and should be on its way later today. Therefore, that dreadful "*" icon will appear on this website until it gets returned.

If the replacement unit passes "The Suction Test", the rating I gave the product will go up; it may even make it into "The Trophy Case" on this website.


UPDATE: 04-30-08
The replacement arrived at 2:22pm PDT yesterday; the unit passed "The Suction Test" that I administered.
Therefore, I've upgraded its rating and placed it into "The Trophy Case" on this website.
I've also removed that dreadful "*" icon from its listings on this website.


UPDATE: 05-19-08
This page also has a very nice review of the Spotlight; I believe this person owns or has access to an automobile too.


UPDATE: 05-20-08
When I measured the charging contacts for voltage, I measured +0.000 volts here; as a result, carrying this light in a pocket with coins & keys presents absolutely no risk of shorting anything out.

Reported to be waterproof & submersible to at least 3 feet


CONS:
You need an automobile to make use of this product
The sample I received is ***NOT*** waterproof (see 04-30-08 update above)
