The handle doesn’t adjust at all. I noticed when I removed the reflector, the LED is connected to the back of it and and directly behind the LED has some type of heatsink that is in the same shape as the rear of the reflector sitting in mid air. But from what I can tell, the heat isn’t transferred anywhere and not connected to the aluminum body. A strange design, but it seems to operate very well. I’d say the heat is obsorbed into the reflector and this heat sink. I’m curious to see how it performs if the becomes saturated with heat. I’ll give that lux measurement another try and see what I can come up with. Thanks.
I’d love to see how the mtg2 works with a 95mm reflector. The star for the XM-L in it now looks 20mm to me. The internal setup of this light is different than I’m used to seeing, how the LED connects to the driver and such. Perhaps I’ll post some photos later today. I was a bit surprised this light is powered by a 4 volt, 7500mAh lead acid battery. A bit higher capacity than the 6500mAh in the description, but that’s fine. It actually never said anything about it having a Li-ion, so at least it’s a very safe light to use as is. But it’s going to get 4 x 18650 Redilast 3100’s wired in parallel as the first mod for it and see how that works.
Andi, then you’ll want to see these photos of the internals.
Evidently, this light uses a different way of conducting heat by conducting it into the large cavity behind the reflector. Not a great way to do it especially since the body is aluminum and could have aided in heat dissipation. But from using the light, I’d say the manufacturer decided to take advantage of this very large aluminum reflector in addition to that heat sink mounted at the rear of the reflector, and both serve to absorb heat. I have used the light on high mode for a while, but didn’t notice the reflector becoming saturated with heat at all.
I’m sure that’ll change once I get to upgrading the driver to turn it into even more of a thrower. I’m hoping you’ll be able to come up with an idea that’ll work well. It’s a great little light and very well made, including very nice silicone wiring of sufficient gauge that does not require replacement.

closed design, unlike this flared version.

Thanks, really like such a format light. Could you measure at 15-20 metres and see what’s the lux reading? (I can convert it for ya) That’d give us a more accurate figure.
I wanted to get this 19.5cm ext diameter T6, but i am not sure if the reflector is optimised. Not cheap too, so decided not to take the risk.
Take your HD2010 and ceiling bounce it. Take the lux reading.
Take this light and ceiling bounce it. Take the lux reading.
Not sure what’s the OTF output lumens of the HD2010 though. You have other lights like SWM T40CS? You can get a pretty ok OTF lumens by relatively comparing them.
I’ll get the lux reading tonight for you. As for this 7.5 inch reflectored light, I’d say it’s driven the same as the Projector light, but has an even larger reflector. Damn that’s big…LOL. Good candidate to upgrade the lead acid battery in it for a nice li-ion too. I saved that link for a future purchase.
I really love the light and build quality inside and out is really amazing considering the price. They actually used the same large diameter silicone wiring I use to upgrade the lousy 30 gauge wiring in most all my Chinese lights. One upside of the lead acid battery is you get proper output from the XM-L, but you don’t have to worry about any unsafe battery conditions. But as I mentioned in an earlier post, I’m still upgrading the battery to some Redilast cells.
I originally purchased 2 of these light, one from BangGood.com (gold color) and one Red one from an Ebay seller. Not having dealt with either vendor before, I just assumed they’d both be damaged when arrived, but having two, I’d be able to fix one with parts from both and the reason for having two of them. As it turned out, the one from BangGood was shipped in the original box and very well packaged and arrived MINT. However, the Red version from the Ebay seller was taken out of its original box and placed in a box smaller than what the light required. Although it somehow didn’t arrive damaged, when I opened the box, it was in some sort of moon-light mode, which it doesn’t have. It could have even left the factory in this malfunctioning condition. It was the lowest moon-light mode I’ve even seen. So it obiously had or developed a short somewhere.
It wouldn’t turn off and could actually have been in this mode for weeks, so the red one I needed to take apart and fix the issue, which I did. So it’s the red version that’s getting some upgrades while it’s apart.
To play it safe, just purchase from BangGood, they seem very into having some BLF business.
As for the 19.5 cm ext diameter searchlight, the issue is that the reflector is not really deep. Yeah i know that the diameter is the main factor in determing throw (focus whatever)….but if you see most of the usual aluminum body T6 lights, the reflectors are of a certain profile (quite deep) which is somewhat similar to the aluminum body searchlight that you have just purchased.
That Zuke 2933 searchlight’s reflector profile is really like those HID/halogen searchlight. So seriously i do not know if it’d throw even as well as your light.
I do see your point with reflector depth and fully agree. Still, I was very surprised to see the beam profile was quite tight down-stream when compared to some of the lights I used in my beam shots in an earlier post. If powered the same as say, a TN31, would it throw as tight and as far, I can’t say, but I think it would make a great experiment for sure and still be inpressive.
The only thing I’m not sure about because I haven’t actually removed the LED and driver, I’m not exactly sure how the LED receives power since the wires are not mounted to the top of the star as a typical light would be. I’ve never had a light in this configuraton where the wires are obviously underneath the LED somehow. But one thing for sure, as soon as I get the battery upgrade done and works correctly, it’s going to get a driver upgrade and one of my XM-L2 installed. Just a matter of time now.
