Great post clockclimb,very informative.One could consider turning the heat sink into a bug zapper unit :thumbsup:,but realistically I know that is not going to happen.
Other than Rayovac Extreme 300. what other brand/model of lantern out of the box w/ same spec (300 lumen)?
I just modded one of the new 240 lumen models from amazon. They have tweaked the heatsink a little. The fins are now veritcal instead of horizontal, and the fins kind of wrap around the 24mm mcpcb. I prefer the old heatsink personally.
What modifications did you perform? I would like to replace the LED with a warmer version, any suggestions?
Hi,
Question. If I were to use 3 x AA Eneloops with D-sleeves and assuming fully charged at around 2,000 Mah, does that mean that I can expect just under 2 hours on high and around 4 hours on low? Not too up to speed on "battery math".
Thanks!
I want to entertain an idea and see if its even workable with this new modded Lantern. Credit goes to Poppy for the idea. In addition to this rayovac mod i would like to solder the ground wire from a male USB plug to the negative post (pre-Clicky switch) and the positive usb wire to the positive post of the lantern. would i then be able to plug it into my 4*18650 battery bank which can provide up to 2A to power the lantern? Also Thanks to Netprince for answering my questions in helping me along the way.
EDIT: just triggered another idea. if it works i should also be able to plug it into my samsung smartphone 2A wall charger no? as it also supples 5V usb spec.
Finally completed my upgrades to the 3D and Mini Sportsman Lanterns. Thanks again to Poppy for the USB idea. it's such a cool feature to have now.
3D Sportsman Mod
Emitter: Cree XM-L2, 16mm Round MCPCB Copper Direct Thermal, T5, 5C1 (4000K) from illum Supply (Should've gone with 20mm board but the tint is perfect)
Driver: 4xAMC7135 (1.52A) 3/5 Mode Driver (Nanjg 101-AK-A1) from illum Supply
Reflector: Took it from my cheap cree XML T6 zoomable flashlight
GITD 14mm silicone tail cap from BG (a little too big)
Reverse Clicky switch from BG
Added standard Male USB plug. Terminated the data wires.
Notes/Comments: Kept the stock diffuser and drilled holes in it for more air flow. I highly suggest using a reflector as others before me have. It really cuts down on the horizontal glare and helps redirect a lot of the light downwards. Using a 20mm star would've been better. Disclaimer: I use the USB power option with the batteries removed as it is wired pre-switch. My assumption is that it would add the USB(5V) and 3D(4.5V) making it 9.5V which would kill the LED?? If you choose to do this mod I would be very mindful and only use one or the other for powering it. Someone more knowledgeable, please correct me if I am wrong as I am just guessing.
Great mods, through and through!
If I read your post correctly, and you soldered your USB wires to the battery box, without disconnecting the original wires that go to the battery box, THEN you soldered the USB input in a parallel configuration, and THAT would NOT add the voltages.
I wouldn't run the lantern with both, the batteries, AND the USB power bank at the same time. I believe that could cause a problem.
EDIT: Clarification, I would not have both sets of batteries connected to the lantern at the same time.
