OK first post for me and I wanted to share my not great ceiling shots
using the MTG 2 leds in the search for a good fairly narrow beam for use on the mountain bike
I have copied this post from over on MTBR as a slow and lazy typist
so hope it works
OK so copying the post did not work so here is a linky to the thread
Hey troutie, you may need to post the photo’s to photobucket then use the href link to get them up here. :bigsmile: please do get them up though as there’s a few of us interested in the mt-g2.
Nice, I can’t wait to get one of these in the host I have, and 3a high will give plenty of run time. The 50mm reflector, meant for an sst-90 should work ok too.
You have to be in the post editor to see the tree. Go to the bottom of the screen and look for 'Post a new comment' or hit the reply button and you should see the screen below. The tree is just below the first smiley face:
great job on the beamshots, looks like the Iris would make a lovely flood beam and the 80mm cutter monster seems like it would have a relatively tight beam and decent throw. Looking forward to your standard fireroad shots + lumenhound.
Welcome aboard Troutie! Thanks for posting all your reflector combinations with beam shots. It looks like it might be difficult to find a reflector that can properly focus the MTG2. With your test bed, have you experimented by slightly lifting the reflectors to see if shimming might provide a better focus? On the trail, it probably wont matter with the sheer amount of lumens produced.
Niwalker have a new NWK1000 light scheduled for March that uses a MT-G2 emitter. Beamshots from niwalkerlight.com
Here’s one:
I remember reading somewhere that the reflector work involved with the MT-G2 is more than half the battle - hardly surprising given the size of the thing
I have a host that I and a few others have high hopes of, its intended for a 9a sst-90, I’m just planning on 3.5a, as I want run time as much as sheer brute lumen power. :bigsmile:
Woody what would you estimate the beam angle to be from that 1metre wall shot
Flashpilot Thanks
yes I did try a bit of uppy downy with the reflectors to see their best position
hey may have a sweeter spot if I could have gone deeper in to the reflector
the iris looks good and is a fit with no modding
the 80mm one is sweet butbdoes have a large corona which for the bike is good .
I don’t really know - the Niwalker link includes other white wall shots, including the NWK1000UT (Ultimate Thrower) with the XM-L emitter, so that might give you a better idea.
