I compared this light to a 2-D cell Magnalite which weighs about the same (1.5 lbs w/battery.) As one would expect given the difference in voltage (12v vs. 3v), the DeWalt appeared to be several times as bright as the Magnalite and has a beam 3-4x as wide.

I only gave the light three stars because (1)It is overpriced, even w/ Amazon's discount (2) Replacement bulbs are also expensive, although they do include a spare, and (3) You cannot focus the beam - a wider "flood" beam would be preferable to the more intense spot for many applications.

If all you want is a general-purpose lantern, there are several 6v dry cell units available which represent better value. However, this one will utilize your existing batteries & charger, and with its solid base and tilting capability can be configured to illuminate the typical work site better than most of its competitors.

BRIGHT AS HECK! AWESOME! (Rating: 5.00)
Review : If you are sick of constantly buying batteries, and never having a flashlight handy, buy this gem. It's awesome, especially if you already have sunk a few hundred into other dewalt products and wish you could use those batteries for something else! It's bright and takes a beating!

DeWalt DW904 Flashlight (Rating: 3.00)
Review : The DW904 can be an excellent accessory to have, but I much prefer the Dewalt flexible models to the pivoting type flashlights because they really handle daily on the job abuse better and also have the added advantage of a long rubber covered flexible neck to wrap around objects for better positioning. My preference is based on heavy use of both types of the 12V, 14.4V and 18V models. Most of the flexible models I currently own are several years old and have had many times more use than the pivoting models ever will, for a good reason. Although they have been pretty well beat up, all are still working fine and I could never say enough good things about them. The on-off switch on all models is fairly well protected but can occasionally get stuck in one position because of heavy dirt or mud buildup. The switch can be freed up easily with the aid of a stiff parts cleaning brush once the mud has dried.
If you do a lot of work in crawl spaces or other areas where dirt, mud, sand and grit can get ground into the pivot joint of the DW904 flashlight, it can eventually cause excessive wear at the joint and damage to the spring loaded electrical contacts located there, causing the light to malfunction without warning at a most inopportune time. One day, I had just such an experience using the 12V DW904 while replacing the motor on a circulator pump located about sixty feet back inside a crawl space under a hotel. The crawl space had absolutely no area lighting of its own and none of the natural light that you sometimes get through vents, so the DW904 was literally the only source of light to be had. About halfway into the job, I was in the process of adjusting the flashlights head to better light the work area, when everything suddenly went pitch black. At first, I thought,...okay..., maybe the bulb had just burned out. I'd had to change the bulb in the dark once before so I new it could be done. Feeling my way around the flashlight, I carefully unscrewed the lens and replaced the bulb with a spare bulb stored inside the flashlights head. The bulb wasn't the problem. I remember thinking, ... "Heeere Lassie!"... because there was no way I was going to be able to navigate my way around obstacles and get out of the crawl space without seeing where I was going. Fortunately, I had a two-way radio with me and was able to get hold of someone up above to grab another flashlight and come down to where I was working.
I don't think this situation was brought about by any flaw or defect in the DW904 so much as that it is just not designed for any type of use that exposes it's pivot joint to continuous abrasion from sand and dirt. The older Makita 9.6V pivot type flashlights I used years ago where also susceptible to the same problem, although none of them ever went completely and totally dead on me like the Dewalt did. You could usually bang the Makita against a floor joist a few times and it would come back to life, at least temporarily.
Overall, if you plan to use your flashlight only in clean, dry locations, the DW904 should be a good choice. On the other hand, if you plan to consistently use your flashlight in damp, dirty environments and other high abuse areas, as most tradesmen normally will, then one of Dewalt's flexible flashlight models is definitely a better and much more appropriate choice.

Excellent flashlight (Rating: 5.00)
Review : DeWalt is known for great power tools, and this flashlight is no exception. It is powered by the same 12-volt rechargeable battery pack that powers other tools in the 12-volt cordless series. The light is extremely bright, and it swivels from straight to angled position. Because it's pretty heavy with the battery pack, it sits solidly in position if you set it down. It's not economical to buy just the light if you don't have, or aren't planning to buy, other DeWalt 12-volt cordless items, because the battery pack and charger are pricey when bought by themselves. But most of the tools in the series come with an extra battery pack and a charger.

Perhaps it's yellow because it's a lemon (Rating: 2.00)
Review : I would have given this product 4 or 5 stars until I read a certain review on this site. I was very happy with the performance of my DW904 12-Volt until it went dead on me a week ago. Just as this reviewer I speak of said, "Oh I'll just replace the bulb", but that didn't do it. Thinking that maybe the switch went bad I took the light apart and bypassed the switch but still no light. I promptly threw it in the trash in disgust because I really hadn't used it that much and I NEVER abused it. Even so I planned on buying another DW904 thinking that mine must have had a defect, but now after reading that another person has had the same problem with his, forget it. I'll probably order a Milwaukee flashlight for I had recently purchased their cordless 14.4 to replace the noisy 12 volt Dewalt I have. (The one that the flashlight came with)
