‘Tis crap if it’s anything like the 5 Ti’s that I got in a buddle deal (4 out of 5 with problems) or the dead Saber that I just got in. Screw me once, shame on you. Screw me twice, shame on me. Screw me three times… no frickin’ way.
Really? These companies need to stop producing over the hill , ancient XP-E LED’s. Why not stick with R5 , XP-G2 in these small AAA lights, they’re meant to be” floody” lights.
OK, that makes more sense of a recent email I got from ThruNite service. They are replacing my damaged in transit TN30 and including a free Tis for the delay. I originally thought it was a typo, but two different emails said similar things.
My Tis arrived today, along with (finally) my TN30NW.
The TIs is identical in appearance to the old model Ti. It is single mode, and appears to have a different driver or contact plate in the head.
The emitter appears to be the same as the old one, as is the reflector. I did not disassemble the light.
Strangely though, it has a smaller brighter hotspot and throws further. I compared it with two of my old Ti, which are very similar to each other on high.
I am at a loss to explain the difference. I used fresh Eneloops in all lights.
It’s nice and simple and is probably all most people need on a keyring, although I really like having several modes to choose from to suit the situation and to conserve batteries.
Youre talking about emitters and reflector being the same, yet Tis throws further than Ti?
Sounds to me, that it has something to do with reflector, it might be deeper/redesigned?
You should take apart Tis and Ti and compare reflectors :D!
Perhaps its driver is much simpler than that of Ti and with that also thinner, thus making it possible to make reflector deeper.
I had 1 Ti with a well centered emitter, and all 5 from the ‘bundle’ deal had off-centre ones. The well-centered emitter had a tighter hotspot. There was also significant variation in output across all of them, probably due to variations in forward voltage between LEDs meaning higher/lower current drawn with the semi-regulated boost circuit used.
