ROP heat

I really like the ROP for its simplicity, but....I'm worried about the heat. I've done some searching, but really can't find anything concrete about using the ROP high bulb in the stock Mag bulb holder/socket. While I'm sure it's not much of an issue for just playing around, I want a light I can use for 40 min or so without melting down, not a showoff toy. Perhaps a relatively tight fitting reflector would minimize heat from the element, but how hot does the PR base get?
 
I've never run mine for more than about 15 minutes, but I haven't had any problems.

One of Download's MagCTowers would definitely help, though I haven't tried them myself.
 
from everything I've read, and I have two ROP's myself, I'd advise using at least a metal reflector and a UCL lens or Borafloat. Otherwise you run the risk of melting either or both. Look on kaidomain.com for this http://www.kaidomain.com/ProductDetails.aspx?ProductId=1739
and this http://www.kaidomain.com/ProductDetails.aspx?ProductId=2131

This site has some pretty good stuff and I've bought from them before without problems. You can also look aorund in the MP for some custom made reflectors by any one of several members. You won't need any switch upgrades. As far as the temp goes, not sure how hot it gets, but I wouldn't leave it bezel down on anything while it's on.Hope this helps! Good luck and have fun building it.

I understand about the lens and reflector, my concern is only about the bulb holder/socket. Yes, I agree about the MagC Tower, but that doesn't help in a D-cell Mag.
 
I use my RoP exclusively on the high bulb, though usually not for more than 15 minutes or so at a time, and I have not had any trouble.
 
My favorite light is my 2C ROP with 2 AW C lithium cells.I have never had a problem with heat,even after running it for 45 minutes.Since a 2D is bigger you would dispense heat better.
 
I've run my Eneloop/Fivemega ROP-hi (Kai reflector) for a continuous full battery discharge once. No damage that I could find.
 
A ROP is a hot-wired flashlight. "Revenge of Pelican."

Here is my 2D Maglite ROP. I use the Pelican 3854-H bulb (the pointy one). This is the flashlight/project that put the flashaholic hooks deep into me while it introduced me to this terrific forum a while back.

The reflector is orange peel aluminum. The lens is heat resistant glass.

I've ran the ROP on eneloops for 20-25 minutes with no issues...now with the 1185 you will smell something funny around 20-25 minutes
 
My 1185 smokes dark newsprint paper in less than a minute. It never quite catches fire, however. Don't fall asleep with it on while reading under the covers!

I have a 6D ROP high - good solid torch with plenty of light, blows away the standard bulb by a very large margin. Currently using some 10 year old 4000mAh Ni-Cd cells, but I have four fairly new 10000mAh NiMH cells so I might buy 2 more and use them.

I also have a 2D ROP Low - very useful torch with good light at a nice colour (fairly white), power comes from a 2xD Li-ion pack from KD. Should run for a couple of hours. The Li-ion pack fried my spare ROP High bulb, but the ROP Low is a bit more tolerant of the voltage.

Both work well the ROP Low gets a little warm, but it isn't much to worry about. The ROP high gets warmer and would definitely have the potential to damage the standard reflector and lens if used continuously for too long. I use an aluminum reflector & glass lens in both ROPs.

Beamshots! A showdown would be entertaining. Isn't it dark there yet:grin2:.

Currently 11am, middle of summer - wont be dark for quite a few hours.

There isn't really that much to compare - the high is a bit brighter, but the low is more than bright enough for most uses and draws half the amps (giving twice the run time). In my case the ROP low is only 2D size so it is more convenient to carry & use - I have always liked the feel, size & weight of a Maglite 2D - now with the ROP low giving me a strong white light (compared to the standard Mag bulb's weak yellow light) I like it even more.

I'm off camping next weekend and will take the ROP low for my bright incan, I'll take a few LEDs for medium and low light. It's only overnight so run time shouldn't be an issue.
 
Maybe i'm the only one but my tower melts around 10 minutes of running time. The tower liquidifys around the bulb holder. I am running elite 1700s in a 2D and mine draws 4.40 amps.

Example of the little plastic piece inside the bulb holder that mates with the spring:

Wow davidt, that's what I feared about making a ROP! Photos are worth a thousand words.
