Hi PedalinBob,
The reflectors in the new model are identical to the reflectors in the old model. I have interchanged the reflectors among my old and new models and did not notice any significant difference, both in terms of their operation with respect to the distribution of light and/or their interaction with switching the lights on and off.
I like the compactness of the older model, but the new model is, probably, structurally superior and would be easier to grip in slippery conditions or underwater. It also has a much better battery compartment.
:devil: The body and battery compartment are identical to that of the Impact XL. In fact, it might make sense for Princeton Tec to sell one body and sell the PR Led bulb as a separate item. When the MAG Led PR "bulbs" come out, I plan to try one in a Tec 40.
I wish that the non-grip section on the new Tec 40 were opaque rather than semi-translucent. It reminds me of a toy squirt gun. It looks like the black model is the only opaque model in this new line. [The new one that I have is red.]
[[MODERATOR: Is it appropriate to request that the title be changed to "TEC 40 discontinued at REI - on sale for $10" if there is no objection.]]
