| DEAL XTREME LAMP, AGAIN HI GUYS, THIS IS A COLLABORATION FROM CHEVROFREAK The problem with the Deal Extreme modules is that none of them use thermal regulation to reduce the drive current to the LED to control the temperature of the lamp. LED's do not like high heat. It reduces their efficiency, shortens their lives, and can cause the tint of the light output to change. The Nitrolon body of the G2 acts as an insulator rather than a conductor, so that heat just stays inside of the lamp and cooks the LED. These modules are better suited for use in aluminum bodied flashlights like the 6P. They'll work alright for short bursts in the G2 (I'd say a max of 5 minutes) but extended use is not recommended outside of an emergency. Surefire recently released a G2L and 6PL that uses their P60L LED module. It has a sensor under the LED to cut the current back when the LED gets hot, in order to prolong life. Well, the G2L has only been out for a few months now and Surefire has already made a change in it. They swapped the Nitrolon bezel out for an aluminum one in order to help dissipate heat. Since they did this with a light that uses a thermally regulated module, it makes you wonder just how incredibly hot the non-thermally regulated modules actually get. Actually, I don't have to wonder since I tested a Deal Extreme 4068 module in a G2 and after just a few minutes it was too hot to hold in my hand, and the tint of the beam had shifted blue. It was perfectly fine in an aluminum bodied flashlight, though.

| TACM III TACTICAL LIGHT WITH REMOTE SWITCH Hi guys, This light has been in the market for several years; it is a great little light and produces 105.5 lumens. I have five of them installed in various long guns that I use for home defense or plinking at night. The pressure pad switch is very responsive and the length of the cable have served me well for all of my applications, I have them in a Mossberg 500, a Ruger Ranch in .30 Russian a Mini 14, a Maddi 7.62 by 39 and a .Mag Tech .22 caliber. I like them for the long guns because they have an excellent range, due to the bigger reflector/lamp assembly than usual (bigger than the Surefire P-60 or 61) and the fact that it is smooth (in my old models) so the throw is much better than is possible in the Surefires using the P series lamps. Why this little company is not better known, it is a mystery to me, the lights are smaller, lighter (made out of stealth plastic material) and more powerful than normal for this size and weight. They have resisted well many rounds of even shotgun slug, and in the almost fifteen years that I have them, I have yet to burn a lamp. TACM III ATTACHED TO THE MADDI BY A WEAVER RING ![]() THIS IS THE TACM III DISSASEMBLED ![]() For pistol work I will still prefer a Surefire with the bigger flood to clear rooms, I am inclined toward the Surefire Centurion III with the P-61 lamp. But for when the gun is a rifle or shotgun the little TACM III have more range due to a more concentrated beam. Here is my usual beam shot from 26 yards, with the camera at 12 feet from the deer, you can compare it with the others lights in my thread. ![]() Cheers Watchmaker

| THE BEAR CUB SMALL LIGHT BIG PERFORMANCE Not long ago to get magnum illumination out of a flashlight, I had to drop down the tube, six of the big D batteries on a Maglite 6 D size. That the light weights three pounds one ounce and measures 19 ½ inches was just incidental to the use if I wanted to get a really good, powerful beam. Later Surefire come up with small lights that could take two and three or four small but powerful 123’s camera batteries, some of those lights, come up and surpass the 181 lumens of the big Maglite 6 D. I am thinking now of the specialty tactical light than Surefire have as the M-4 that uses four of the 123 batteries for 225 lumens for one hour run time. Incidentally the M-4 is not precisely inexpensive, costing $330 USD from Surefire or their dealers. The only problem is that the little 3 volts batteries are quite expensive, and using four of them for one hour run time can cost you $8.00 for that hour. And that is if you buy them at discount over the Internet, when purchased in the camera stores (such as Wal Mart) the little 3 volts batteries cost as much as $4 each. So a light of the size of the Surefire M-4 (9 inches long) was highly desired if it could be made to run on rechargeable batteries, to avoid the big battery expense of the M-4. Enter the Bear Cub, a nine inches light, with a 13 oz. weight that is rechargeable and uses Lithium Ion batteries. This little light makes 220 lumens for 90 minutes of run time, and then recharges its two batteries with a fast charger that is included, in three and a half hours. The Lithium Ion batteries can be recharged up to 1,000 times and when they eventually get depleted can be replaced with $30. HERE IS A PICTURE OF THE BEAR CUB LIGHT, NEXT TO THE SUREFIRE M-4. ![]() AND HERE NEXT TO THE MAGLITE 6 D ![]() And here a couple of beam shots at 26 yards for comparison. MAGLITE 6 D ![]() BEAR CUB ![]() Yes the little rechargeable Bear Cub is characterized for an intense white light, and a run time of 90 minutes, all in a small size that can fit in any glove compartment or trench coat pocket. Best Wishes Watchmaker

| THE BOREALIS FLASHLIGHT 1050 LUMENS Three years ago the Borealis flashlight was conceived to be the most powerful military/police flashlight in the world. At 1050 lumens the beam of light is very similar to a two million candlepower spotlight, all that power cased in a 12 ½ inches long, 28 oz. light, that will run for 50 minutes before needing a recharge. Then the light uses a fast RC charger that does the job of recharging the high current batteries in 90 minutes. Three years ago everybody was in awe of the Surefire M-6, a military/police light that makes 500 lumens for 20 minutes run time on six disposable 123’s batteries, at a cost of almost $12 per twenty minutes run. When the agency pays for the batteries, all is well, but for the civilians that wanted to have those mega lumens of light, there was no option. Black Bear Flashlights wanted to produce a rechargeable light that surpassed the M-6 and still be affordable for those with mortgages and families, and the result was the Borealis 1050 lumens flashlight. The light was conceived to make use of a well known flashlight shell that is available anywhere, that way after years of hard use, the shell can be replaced for less than $20 USD and in ten minutes of the owner’s time. The super-bulb that is almost 3 ½ amps needs some very powerful batteries; those nine AA batteries of high current are housed inside a Rolls Royce battery carrier that has also a charging port on the negative side. Plugging the RC fast charger in this port for 90 minutes, will recharge the powerful AA Nimh batteries. THE ROLLS ROYCE BATTERY CARRIER AND THE RC FAST CHARGER ![]() The Borealis also has some especial components to cope with the increased heat from the bulb. A ceramic switch/bulb holder, a solid aluminum reflector and a Pyrex lens, take care of the high temperature issue. The BOREALIS is the highest intensity incandescent flashlight available in the market. Some HID’s lights throw more lumens, but those are considered searchlights and not flashlights; as a HID can take as much as 30 seconds to start up, they are NOT instantaneous as the incandescent flashlights are. HERE ARE SOME COMPARISON BEAM SHOTS AT 35 YARDS WITH THE MOST POWERFUL MILITARY/POLICE FLASHLIGHTS. THE CONTENDERS FROM LEFT; MAGLITE 3 D, MAGCHARGER, ULTRA STINGER, SUREFIRE M-6, AND BOREALIS ![]() MAGLITE 3 D (the most popular police flashlight) ![]() MAGCHARGER ![]() CONTINUE IN NEXT POST

| ULTRA STINGER ![]() SUREFIRE M-6 ![]() BOREALIS RECHARGEABLE ![]() Black Bear Flashlights spends several hours on each light working on fixing all the internal resistance issues and pro-gold all contacts and components for an increased conductivity. This results in their trademark of intense WHITE light as more voltage reaches the super-bulb. This bulb is not a flashlight bulb, but one made for powerful medical instruments. THE BOREALIS ROYAL MODEL, WITH THE NEW LOW PROFILE STAINLESS STEEL CRENELLATED BEZEL AND QUICK DETACH SWIVEL. ![]() Police officers have adopted the Borealis for its tremendous throw and flood capabilities; hunters have abandoned their spotlights for the easy carrying of the Borealis, and civilians looking for a powerful light for the car or for home defense are flocking to the Borealis flashlight. Respectfully Watchmaker

| THE COAST MINI LIGHT I discovered this small light a few years ago in the fishing aisle of a Wal Mart store, it was perfect for tying small flies to the end of my 5x tippet when fly fishing in the dark. Clipped to the pocket of my fishing vest the neck could be positioned as desired for the light to fall in on the fly, it took just a few days to realize that was ideal for writing tickets or for navigating with map and compass in the woods or when doing as a co pilot in the car. ![]() The instructions said something like 90 hours of light, it most be right because in four years of using it a lot, I haven’t yet put new batteries on it. The batteries are four of the AG 5 button cells, not exactly a household item, but available in Walgreens or Eckers. The light is a kind of flood, not too intense as to make you lost your night vision, but enough for the chores I mentioned. The little light also has a ring to hang it from your neck or attach it to your key chain, but my preferred method is to clip it to the shirt pocket, there is so small and unobtrusive that is hardly noticeable. Or you also can clip it to the bill of your cap, like that I have recently exchanged a faulty wall switch, and it is much better than holding a bigger light in your mouth. I think that I pay for it near ten dollars, well worth the price if you like me are a user of lights. Cheers Watchmaker

| ULTRA FIRE FMR1 REBEL LUXEON 200 LUMENS ONE CR 123 A BATTERY I bought this light from Deal Extreme for $23.24 shipped. I was very curious to try one of the Rebel 200 lumen new Luxeons and I think this is the best way to try one inexpensively. The light has a click on, click off switch and five modes of intensities. The low mode is 30 lumens and is said to last for 24 hours. Another is 100 lumens for six hours, and the 200 lumens mode is three hours; then you have a strobe mode and an SOS mode. I used a new Battery Station 123 and in the high 200 mode it lasted for ½ an hour, and it gets hot very quick. I don’t know if the poor run time is the fault of the battery that was under-charged, or if the light will perform the same with others 123’s, but that is the results I got. ![]() Due to the small head, the flood effect is quite pronounced and the throw is poor for a 200 lumen light, but I was expecting it to be that way based on experience with other small headed keychain-type lights. ![]() Two hundred lumens in a two inch head of an incandescent will put a level of illumination that is tremendous in comparison to the small head of the Rebel 200 lumens. So we are in a time when we can no longer make an assessment based on the lumens figure, that is when the comparison pictures that I have been taken show the value, as the viewer can see for himself how the different lights with the same value in lumens output perform in real life. If I consider the low price I like the little light in general, excepting the side switch that can be a little hard to find in a rush, as it is kind of recessed in the head of the light and difficult to find by feel alone. I will have preferred a tail switch such as I have in my Fenix L1D, but it is a tremendous price difference between the two lights, so all things considered I think that the Ultra fire is a great value, and I can put up with the side switch. After trying to like the clip for a couple of weeks, I ended throwing it away, it is too flimsy and I will not trust it to keep the light in my pocket. The light is regular anodized, but had stood well the use in my pocket with keys and coins. Here is my usual 26-yard beam shot against my deer head with the Ultra Fire 200 lumens ![]() And here is a beam shot with the 220 lumens Bear Cub rechargeable that sport a two inch head and have a range of 150 yards. ![]() All the best, Watchmaker
