Hello RickCarpenter --
Welcome to CandlePowerForums !
:welcome:
I'm very familiar with the TerraLux TLE-5 (MiniStar2) 1watt Luxeon upgrade module.
I've found that the NiteIze 1watt Luxeon upgrade module is
equal or superior in every respect to the TerraLux TLE-5,
yet the NiteIze lasts an hour longer on a set of batteries.
That is, lasting roughly 6 hours, rather than 5.
If, indeed you want MORE runtime than that, at a lower light output,
i can recommend the TerraLux TLE-10 upgrade module.
This is also known as the TLE-20 module, when it is packaged
along with a "PR-2" type bulb base.
Regardless of what it's called, TLE-10 or TLE-20, it'll last twice as long
as the Luxeon upgrades, on a set of batteries.
TLE-10 (20) uses a one-half-watt Nichia Rigel emitter.
Natually, the TLE-10 is
not as bright as its Luxeon counterparts,
but i've found it to be plenty bright enough for many of my uses,
when it's gotta' run All Night Long.
You will find
all 3 of these Upgrade Modules available at
Battery Junction,
an excellent place to do business with. :thumbsup:
May i suggest that you
avoid the NiteIze 3-LED upgrade module,
which is often available on local store shelves, for about 6 bucks. (US)
Why ?
Because the TerraLux TLE-10 upgrade is superior to it, in every respect.
Believe me, i've compared 'em.
(OK, i admit, it does COST a bit more than the 3-LED module)
Hope this information is helpful to you.
