One thing I noticed is that the Meritline Sipiks used to have Cree Q3 emitters. Seems that they've recently switched to Cree Q5 emitters, which are what's used in the TT lights. Wonder if the differences you noted were due to comparisons of lights with two different emmitters?
One other...
The coupon is dead, now $7.10 each (still a great price).
Today (might be today only) you can get a 3 pack of what looks like the same thing over at Meritline for $19.99 ($6.66 each, free shipping). States that it has a Cree Q5 emitter and puts out 280 lumens, but as we've heard, that's not a...
I was thinking that the 3 AAAs were likely configured in series and therefore delivering in the range of 3.6 - 4.5 volts as compared to 1.2 - 1.5 volts from a single A, and therefore more power (brighter), but at the expense of run time. Now I'm wondering if I was missing something. Does the...
Thanks MrTeal. Looks like we've finally got someone who knows what they're talking about as compared to, say, me, who's working off of assumptions and impressions : ).
So what about a relative comparison of brightness for a similar flashlight using a single AA battery vs. 3 AAAs? I'd wager...
Likely, if all other things are relatively equal (see #31 above). But AAAs are gonna be much more expensive over the long haul unless you've got rechargeables. My experience is that the AA model is great and plenty bright enough - unless you see it next to a similar AAA model, after which...
Just to clarify, my point is that I'm pretty sure that the 3AAA batteries are connected in series, so you're driving one of those flashlights at ~3.7 volts (with 1.2V rechargeable AAAs), same as if you used a 14500 battery in a similar single A model light.
But the power (watts) question...
The more I think about it the more confused I become regarding possible differences in light output between the two. Same voltage (let's say 3.7 with the more powerful 14500 battery), slight difference in output for the Q3 vs. Q5 emitter, but the TT one is 7 watts vs. I calculate 3 watts for...

I missed that. But from what I've read, a Q5 isn't necessarily 'better' than a Q3. A Q5 is slightly brighter, but the Q3 apparently has a more neutral tone, which some experts seem to prefer. A quote from someone on a candlepowerforums.com thread discussing the issue:

Dealextreme.com has it for $9.20 shipped (SKU 39585). Meritline has it on sale fairly often in either the black or silver model for as low as $8 shipped. Both ship from China so it takes awhile.
This is a great little light with a AA but not as bright as with a 14500 battery. If the merchant...
SuperSix- Asking for and sharing information isn't the same as thread crapping. Do us a favor: read back through the comments and point out all of the ones you feel are thread crapping. I think there's a lot more hypersensitivity going on here than thread crapping, lol. I saw one post that...
