Lumintop could easily manufacture an extension.. I don’t think it will cost much..

why limit to 18650 only, how about 21700 or even 26650? tube size may be bigger, so is the capacity.

Because 18650 battery carriers are already designed.. less work..

I actually saw one guy from blf was going to design an extension for the blf gt… I don’t know what happened..

Yep… Thumbs Up And at this point in time 18650 is far more popular than 26650 which is far more popular than 21700.
That may or may not change in years to come… time will tell.

Here is a link to the 3rd battery carrier design for the blf gt.

I rather see lumintop make an extension.. so all the pattern will match up.

I am just about ready to Sign up for one conversion kit
(still trying to figure what I want / need to order)

hopefully the neutral tint will be in the 5000k-5500k range?
with a “wow light beam” (or should I choose the cool white for this?)

I would add an extra bat carrier
-* if* a battery tube coupling can be purchased (so I can actually use it/ lol)

do I need a spare reflector and lens?
not sure why people a getting them? (or will these just collect dust in a box like my short tube w no coupler?) Facepalm

if we change our mind can we add parts later as needed?
(I really don’t know enough to make the best informed decision and this will be my first mod – but I can solder! )

I wish they would offer the engine and button section
( so I could simply switch back and forth if desired )

will this mod still throw the light for approx. a mile ?








if ya can’t fix it with a hammer,
you’ve got an electrical problem

Some people want an extra reflector and lens. If you dont, that is okay.

Orders can be changed later.

The throw distance is ANSI-FL1 rated 1400-1500 meters. This is conservative and is also dependant on the emitter chosen. With a sliced dome it should be well over 1 mile. A CW emitter might even bump it up even farther.

Has anyone with a GT70 prototype compared it to the Thrunite TN40 or a BTU SuperShocker? I would be very interested in such results.

@ Giggle Monster Team:
Just out of curiosity: Why did you choose to use an FET driver for the BLF GT70 and not a boost- or buck driver? Personally, I like the idea of constant output when voltage decreases. For sure, the FET will deliver the highest performance when pushing the light to its limits but this can only be done once with fully charged cells.

Both of those lights have significantly smaller reflectors which means their hot spot is bigger which means less throw.

The TN40 has 4 x XPL, which is basically very similar to the 4 die xhp70, but it has much less output which gives it much less throw.

TN40 = 1150 meters
Shocker = 750 meters

Here is what TA said in another thread about this driver.

Very nice numbers Newlumen. It seems the TA driver pushes harder than Vinh’s driver that makes 5500 lumens and 480kcd with the 70.2 GT.

Skylumen may be using a Buck driver. In which case it will have a lower max output in order to have any regulated runtime at all. This is why I ditched the idea of a buck driver after a month or so of work on one when I ran some early tests.

The regulated runtime would be so short and you would be giving up performance everywhere else, it just didn’t seem worth it. So me and Del decided to just go with an FET driver which led to a whole lot more prototyping and testing to get this driver.

I think we all wish manufacturers would sell products at prices below their cost to make and ship them, but that’s how companies go out of business. Shocked

So if you got a GT at $115, consider yourself lucky. Deals like that are rare. Now Lumintop has to make up for lost profits. Crying
Lol

Amen… Thumbs Up . The first 500 price of $115 in the original GT Group Buy was a rare amazing gift. The next tier price of $158 was pretty much a gift too. Beer

But like you said basically…. a company cannot survive if they do not make money. It is simply math…… Wink

Maybe they could…if everyone here signed some kind of a 10-years-total-care-agreement with Lumintop, obligating to buy at least one of their upcoming flashlights. Silly

As was pointed out above it basically boils down to the FET driver offering better overall performance for this light.

It will be brighter then the buck driver for any given input voltage from the batteries and since this light will virtually always be used at high power, the FET driver makes more sense.

The buck driver would be a better option if this was a light that would be run at low power levels for extended periods, as that is the only place it would see a benefit (and the benefit would only be a bit longer run time).

I have been on various flashlight forums for around 10 years. I’ve learned quite a bit about presales and group buys. If you want the best price get inline early because the price always goes up. This doesn’t matter if it’s a custom maker or a well known manufacturer. But know the risks. Besides dealing with unknown manufactures or designers, not the case here, you risk getting a dud or worse, an unsafe light. But there are other things the early adopters often lose out on such as improvements in binning, features, safety, quality controls, and extras included with the light. Some people are willing to wait for the final form and wanting to possibly get the absolute best version. It’s all calculated risks and what works best for your budget.

Just a question. The conversion kit should ship via regular China Registered Mail or Prioritiy right? Don’t want to repeat what happened with my GT.

There’s no replacement for displacement.

If that is all you are ordering, yes it will not be shipping with DHL, it would be far to expensive.

I want to change my emitter from neutral to cool. I want maximum brightness. Do I need to do anything?
