Seeing as how all of your other points are just your personal opinion, while the thing you concede is the only factual aspect of your argument, I'd say your defense just got blown.
What is one person's high price is another's reasonable one. We are already talking about a $60 6P light and a $55 drop-in module, for a total price of over $100. It's not as if the OP asked for some bargain basement solution for some cheap DX clone.
If you want to debate pricing, I've gotten a KT1 on the CPF B/S/T forum for $50. I can build a tower for $40 in parts. And I have. I cited the $100+ cost for an assembled tower to provide a worst case costing. Thus, my total pricing is $90 for the proposed solution, with a very strong price/performance ratio.
What is the tail current draw for the Dereelight drop-in? What's the lumens? What's the lumens stability vs time (i.e., heat buildup resistance)? What's the hot spot lux? I get ~0.5A for the XP-G using 2xLi-ion, getting perhaps about 250 lumens, 20,000 lux@1 meter, and long run time in return. I don't have an integrating sphere but measuring hot spot lux vs time for my KT1 THs has shown a lux drop of about 4% after about 25 min of continuous operation and holding that for the next 30 min.
I think you just love to argue and bring up ridiculous points for the sake of arguing.
the most important "fact" of my argument was that he didn't ask for a turbo head kit. He asked for a
drop in module if he couldn't modify or adapt the M60 for more throw. So I conceded that the turbo head will fit when I previously said it "may not" and to you that blows my entire "defense" out of the water as if it was even important. Its not. Its a side issue to something which points out to me again, you just love to argue for the sake of arguing. I pointed out a viable easily obtainable module he could drop in to his light and improve his throw. That is also a fact. Whether he likes it or not or its the best possible module is a matter of opinion, but pointing it out that's there to be had is a fact.
You brought up the numbers for the potential cost of the turbo kit, not me, now you are changing them. Regardless, I will concede up front before you even go there, that you got them at the price you stated and they could be had for that price by diligent searching on the marketplace forums over time. Its still not the same as buying a complete DBS V3 that will do all of that for $99.00. something he doesn't have to hunt and hope he can get it "used" on the marketplace and put it all together himself and then hope it works. As to the lumens and lux and all that. You are stating specifications and making references to something the OP did not state as requirements again to just drag more arguing points of yours into something. I never mentioned any specific values or argued that the example you were given was good bad or indifferent.
the DBS V3 will definitely outthrow the Malkoff M60 ( his reference unit) and has more than 20000 Lux at 1 Meter. I believe the V3 with the latest R2 pill will outthrow your turbohead kit as well. I have not measured its lumens ( no one asked for more lumens or even used it as a reference) or its run time on a set of batteries nor do I care. The DBS V3 can be had with various pills to run it on either 1 X 18650 or higher voltages which will reduced current draw and increase run time. The Dereelight modules also come in various voltage drive configurations so the OP can simply pick one of his choosing.
He could go buy the Tiablo A9 for less than your option and still have a complete flashlight with more throw. He could get it with the optional aspheric lens head and definitely have more throw and still be at or around $90. You could have mentioned that.
My 3 options are easily obtainable and viable options that don't require putting a turbo head on his 6P and trying to find one at a discount price that may not be available on the marketplace to make it cost effective, plus other parts. But hey, its just personal opinion. Or is it a fact that these options exist, and are more cost effective then your recommendation as you originally stated. And I nor any one else stated going the ultra cheap DX route. Again, you just love to argue.
So I am sure you will argue with this, but I am done. He as viable options.
And just for the record he is of course welcome to buy the KT1 or 2 turbo head kit and try to fit into it whatever he wants, its a free country, not saying he can't, just wondering why spend the money for those parts when he could have a complete second flashlight for less money and accomplish his stated goal.
somebody asks for help to fix a flat tire and you probably want to tell them how to build steel belted radials and where they could buy rubber. :thinking:
good luck morris.
