Inexpensive PR drop in for PT Tec 40?

gunga · Jan 17, 2007

Hello.

I'm wondering if there is an in-expensive drop in for the 4 cell PT tec 40?

I suppose it is a lot like an Impact XL except for the bulb and rubber exterior.

The SMJ LED PR drop in looks ideal but only works for 2 cell lights.

Any thoughts?

The nite-ize C/D pr bulb is inexpensive: http://www.niteize.com/productdetail.php?category_id=28&product_id=127 ~$10 in stores, all the other drop-ins are triple that price or more.

Anything brighter?

I heard those run for days but are super dim...

There are plenty others that are brighter but are not in the $8-$10 price range

The PT40 isn't good for a high-current LED conversion because the bulb is completely encased in plastic, and there's very little metal contact for heat dissipation.

I have a Tec-40 and a Tec-20. I tried the SMJLED-PR in the Tec-20. Wasn't impressed at all. There was basically no throw and all the light just culminated into some floody, bluish circle that wasn't really useful.

I have other lights the SMJLED-PR excels in for what they are (Coleman 2D floating, for example.), but the Tec 20/40 just isn't one of them.

With that said, If Princeton-Tec find a way to utilize a new Cree (without being too under driven) in a Tec-40 body, I'll be all over it.

I wonder what they did different with this model (named: The Shockwave) that has 3x3watt LEDs to deal with the heat:

And wonder if similar can be used in their smaller models...

I think that PT relies on the light being submerged in water to dissipate heat in the Shockwave.
