I understand that this insert is not going to allow this light to compete with a Sten or Scurion or other 300 plus dollar high output lights. A souped up Mustang will not compete with a Ferrari on a road course. I cannot think of any other lamp in the price range that will allow you to run at 200 plus lumens for extended periods of time like a Sten, Rude or Scurion . I am sure somebody will correct me if I am wrong and maybe I am. Keep in mind this is a 80 dollar insert, it will not compete with a 375 dollar light. It is a VERY nice option for somebody who does not have several hundred dollars to spend on a light that has a Duo sitting around collecting dust. Like you I use the high for temporary spot only, just like the high is designed for on other lights in that same price range.

On paper it's capable of putting out this many lumens for ~3 hours with a set of Eneloops, but I don't think there's any sort of thermal regulation that reduces the power to maintain a reasonable temp. Apparently the lamp started smoking after awhile (not sure how long). Anyone else have any experience with this?
When I do use it I generally expect to run it on medium (~130 lumens) for general caving, and use the high for spot-lighting domes and such, so heat dissipation may not be an issue. If this is a limitation though, it might be good to communicate it.

Used Duo off eBay and a Custom Duo full face insert should keep you under your budget. It's one of the best lights there is for the price

Princeton Tec Apex is absolutely your best bet. It's not perfect -- tremendously wet passage will test its less-than-stellar record of waterproofness -- but you can't beat its bang-for-buck in terms of light output, versatility, battery life and cost.

Do not forget you have to put a battery in that thing and Oh Yea, you have to charge that battery. I do not think they come with battery and charger. Or you can feed it 123s $$$$. I am hard pressed to believe that with one bulb it has the same optics.It is my understanding you have to change the lens to change from a wide spread to a spot , with the custom duo you have both at the same time. 10 bucks for the 18650 and another 10 for the charger( 10 bucks sounds very cheap for a quality charger) you might want to bump that up to 120.00. For me there is just something about using eneloops and a La Crosse charger that I already own that just appeals to me. Also I know that the CD will also run off good ole fashioned AAs that you can find anywhere . Also Marduke, I could not agree with you more on the battery use of The Apex. That thing eats batteries first and ask questions later.Caver John wrote:Spark st/sd series lights, @ $100, noted it's 20 more than the insert but...
Lots o light!
I was thinking the same thing as the person who experienced smoke with the Custom Duo is someone who knows a lot about lights ?? This person must of missed that and the fact that many other lights in this price range (Apex, Fennix ect) are not designed to run on the high setting for extended periods.Must not of bothered to check your site before performing such a test. I will admit that there are many on this forum who know more than I , BUT I know a good one when I see one.bif wrote: As a consequence, the higher power modules have always had a loud health warning (communicated on the website) regarding sustained use on the hghest setting.

Oh, and the battery life (really system efficacy) is about a 1/3 of something like an updated Duo or a Fenix.

I don't disagree with any of these points -- and I use a Stenlight exclusively -- but we're comparing a $90 light (Apex) to a $200 light (Petzl Duo 5 is $109, plus the CustomDUO full-face ugrade is $92 in USD right now). That's not to mention Princeton Tec's lifetime warranty, of course.
Repeat: the CustomDUO upgrade ALONE, without a headlamp to put it into, costs more than a new Apex.
But you guys can pretty much keep your cheap plastic commodity-grade lamps anyway... I'll keep my Sten.
