    Hi BB
    The optics shine the light side and down -great for reading ect. on a table -the diffuser is blinding all the time,moreso after the LED upgrade and shines much less downwards.

    I'll be trying the LC1 medium Cree optic and Cree LED tonite and also a recently arrived Khatod 17mm stippled reflector and Seoul LED.

    Hopefully these 2 will give a wider beam pattern -but we'll see.

    Hi Mark
    Thanks for the heads up on the optics and dome - you are really stocking a great variety lately.
    The LC1 optics are a welcome addition to the Cree range and i'm very impressed with their performance compared to others i've tried.

    Cheers
    Dom

    The difference between that and a Q5 would be negligible in this application.

    Thanks! I ordered the stuff today, 10200 optics and the R2's (price difference was cents), can't wait to mod!

    Hi Osci
    Just a note with that optic if you won't be using the holder that comes with it.
    It rocks on the Cree dome -so you will maybe have to put a small weight on it while it dries -unless you can level it without it tipping to the side.
    You could even use some sticky tape to keep it centered while the silicone dries.

    Cheers

    Well - i tried the Khatod 17mm Seoul stippled reflector and it looked crap -so i won't post that.

    One thing i found is that you can use the optic out of the EOS headlamp on the Seoul -almost identical beam to the Seoul 10deg optic.

    The Cree LC1-M optic i tried is very nice -comparable to the Carclo 10200 -maybe a little less bright.
    Very happy with it all the same.


    I actually soldered the Cree in without disassembly - getting lots of practice

    I have added a pic to the room shot post #26 and one to the table shot post #17

    Cheers

However, that light would be wasted outdoors. For example, night time on an outside picnic table.

    Obviously, the optic/reflector focuses much light directly sideways. But the question is, does the optic help throw more light downward to help light up a table surface?
    I have some pictures taken from a much higher angle of the table top showing how each lights it up. I will post them later from work. It should help you see the answer to your question.

    Here are the pictures as promised. As before, color balance, exposure, focus, etc were all constant across this set of picture. The exposure is not the same as either of the previous two sets of pictures.

    Baseline:


    Stock Low:


    Mod Low:


    Stock High:


    Mod High:


    Hope this helps.

    Now the most important question is; would either of you fine gentlemen be willing to do this mod for those of us with no modding skills whatsoever??

    One thing i noticed with the Ledil LC1-M Cree optic is it has the most artifact free beam of all the optics tested and throws more light downwards and a fraction less upwards.

    This if probably because it has an overall longer length than the others.It also has a nice flat on the emitter side which sits and glues well to the Cree emitter ring.

    There are now 2 places to get this from.

    Brum should have more in stock soon i think.

    I tried a Q5 WG in one of mine, had high but low flickered so I put Lux 3 UWOK's in a couple of these and I am happy.

    Very informative thread.

    Menards (in Ill-annoy and other states) has extended their sale on these lanterns; $6.99 at the store, plus $3 each rebate (limit 2, coupon in the store, rebate is a store credit).

    The one by me rearranged their flashlight section and the Sylvanias were definitely de-emphasized; they used to be up top but are now at the bottom (and sold out... wonder how that happened...) rather sounds like the person who was told these were going away soon was given the straight scoop.

    Guys, thanks for the extra pics and info! Both of you are doing some great stuff here.

    Sounds like the LC1-M is exactly the ticket for my intended "outdoors" mod.

    Well I received the R2's and the Optics, I was sort of expecting more for the cost of the optics, they're only plastic, anyway, I modded my first lantern, it took a few goes to properly solder the R2 to the base, the "-" had enough solder to re-solder but the "+" I had to add more solder, the silicon is currently drying so I'll get to test it tomorrow night, I was sort expecting the R2 to be brighter, though maybe because it's running off 4AA and not a CR123. I'll take some pics tomorrow.

    All optics for flashlights that I've ever dealt with are plastic. I wouldn't call them "only" plastic though - it is often the best material for the job.

    I was sort expecting the R2 to be brighter, though maybe because it's running off 4AA and not a CR123. I'll take some pics tomorrow.
    4x AA is more voltage than a CR123 certainly. And regardless of the battery that feeds it, the buck circuit is going to determine the brightness of the emitter by controlling the amount of current that it sees.

    Problem is that there isn't enough heat sink to drive the emitter much harder. Wouldn't be all that difficult to do - just wouldn't be prudent!

    Have any of you discovered the super secret red lantern mode/mod?
    If you have you know what I speak of but may never admit it.

    I have tried a Cree in 3 different lanterns and low flickers in all, p4/q5 it makes no difference.

    Weird... I've only tried the SSC P4's, but I've mod'd 6 lanterns so far and haven't had any flicker.

    So this device hasn't got a regulator like some of the torches do? So once the batts get to a certain voltage then it switches off?.

    Hi Beamhead
    Love the secret red mode - have to try that yet

    Here's a few pix of how i do the Cree -haven't had any blinking
    low mode yet so must be doing something right.Can't think of a reason why yours would blink though

    This is just showing how i have the Cree just over the pads -not enough to short on the middle emitter pad.


    Build up a bit of solder on the emitter to make it easy to bridge to the board pads


    Centre the LED,tin your iron,hold the ring near the unsoldered corners with
    your pointy pliers -a little downwards pressure and job is done in a couple secs.


    Cheers
    Dom

    It's got a LED driver circuit. I would say it's regulated from the output graph I saw posted here.

    Just a note if using the LC1-M optic.
    These are a bit longer and heavier that the Seoul optic so they will knock off with a good bang on the side of the lantern.

    Could be an idea to use the holder with them for more stability.

    Also a good thing to do is give the bottom of your optic and the emitter a clean with some isopropyl alcohol before siliconing.

    Cheers
