[♛ FreemeGB-NOV] Haikelite HT70 4*SST70 6500k 17000 lumens 18650 Flashlight - ALIVE!

Well that all depends on who the manufacturer and/or builder is. Most are a little off, but I have not experienced such Over inflated numbers like this light since my T-Mart days in the beginning of my hobby 8 years ago!

They rated it 5000 Lumens too high and 500 meters Less throw than it actually has. :person_facepalming:

I do have several. My Xtar VP4 is my main charger. I also have the Zanflare C4 and Lii 402. But these two often have slightly different terminating voltages. I know in real life it shouldn’t be a problem; it’s primarily an OCD thing. To me an 8 cell light needs an 8 cell charger.
This light would have been more interesting to me with 6 or 8 emitters and a slightly larger head for more heat dissipation. But then you probably need a different driver to prevent the risk of the FET going poof.

MT09R only uses 4 cells and that can do over 16,000 lumen (certain ones). So 4 cells should not hurt it.

That is Haikelite for you. It’s not the first time they got specs way off. Sometimes I wonder if they just rate things by “theory” with no actual testing. IDK.

Yes,this is my First experience with Haiklite. Now I know what to expect. Unlikely I would buy one of their lights until one of you guys test them and the numbers are at least 75% to 80% of what they advertise!

It’s been awhile since the MT09R group buy and I do remember reading that they don’t have actual test equipment so all their numbers are based on calculations/estimates. :person_facepalming: I think all small flashlight makers should just buy a Texas Ace lumen tube for output and cheap lux meter for throw. Not that expensive. Maybe Freeme can recommend that to them so they don’t make themselves look bad every single time they release a new light.

They just probably make a wild estimate on the lumens and throw numbers, i wish they didnt just guess numbers out of the blue, i remember from the mt09r gropbuy we were promised lumens etc it didnt turn out quite what was said first… so same here its not really a big deal really they just make it sound the light is better then what is makes in reality… still a good deal imo dont see any other lights like this atm ?

Thanks for the info.

That surprises me. They have to make enough money to buy that equipment. Maybe just laziness!

I remember johnnymac had to tell David from Thrunite how to measure properly. At least they had equipment!

MATEMINCO owns a 1m integrated sphere if i am not wrong. HaikeLite measurements were reasonably accurate back in 2017?

Everyone wants to look good on paper as it has direct relation/impact with their sales. You can't really avoid, as it happens in almost all industries.

True but reputation is important too. Olight sells the most flashlights and all of their lights measure higher than Olight’s specs in my calibrated lumen tube. My lumen tube usually measures lower than others on this forum. So even a company that under rates their products can sell really well due to their reputation and reliability.

On Banggoods website there is a section for questions. One question was can it take FLAT TOPS? The answer was YES.

Q:Can it take flat top batteries?
A:
yes

Can you confirm or refute this?

Thanks

This is why I asked the question in post #82 about GA BT OR FT??

I would like casi29061965 to answer the question OR someone who actually has the light.

Thanks

Two batteries are always in series and there is no battery holder, so if I’m correct that would mean it depends on whether the positive terminal of a battery will make contact with its negative end.

True. But there is also a possibility that the length of two flat top GA cells in series is on the short side or too short to make proper contact.

lol! There is a reason why I asked casi29061965 OR someone who actually has the light…………other than that it is pure speculation. :wink:

You have to know your cells.
Sanyo GA are considered raised flat tops, not flat tops. If you look at them you can see they stick up and will make series contact.

Regular flat tops will not work.

Raised flat tops or button top will work.

Appreciate your opinions, but like I said, it is All speculation until someone tries these FT cells in this light.

Knowing cells helps but is not definitive until they are tried in the light! Every light can be different.

Still waiting for someone who actually Has the light! lol!

I hate to say this, but your quite wrong. This particular flashlight is irrelevant. It only depends on the cells. If you have 2 of a particular cell you can see for yourself if they will make contact in series or not. Or better yet, take a single cell and a straight edge and see it the top extends above the wrapper.

Look at this picture, you see there is a black ring around the brass ? disc in the middle. This means the positive battery end needs to stick up a little bit. All button tops will work. All solder blobbed flat top will work. (The black ring is there for reverse polarity protection)

Button top only. I thought i have mentioned before?

Yes you did mention it.

I will disregard the post on Banggood[Where the question was posed and replied FT will work] an one members opinion on here about FT!

Thanks

Are you still expecting December 31st as the “Target” date for NW to come to fruition?

Thanks
