FT Generic EA4

So, browsing FT site, and saw this:

Interesting. Now someone with money to burn do a comparison.

It is the same light, same UI, body and output ratings as far as I can tell. Whether they are seconds with issues or just overstock is the question.

Stop it! Just stop!Tongue OutWink

Seems to me that this is Fasttech's way of getting back at Nitecore for that MAP issue

Looks almost identical, but the UI is completely different. There is no two level switch. It may have most of the same features, but the UI is very different.

Anyone dropped the $ on this light yet ? I’m tempted as I have an Ea4 so I could use it for spare parts

Any codes for FT?

I think I will buy it.

BLF but i think they did away with all coupons recently

Thanks.

Saved $1.80 with the BLF code.

Hmm , just ordered the clone un marked EA4 , 12 days stock delay, oh well no rush have 3 orders in the system from FT, mostly for family

Yeah, it would be nice to think this, but my guess is it is just a part of the clone culture and will show up elsewhere eventually.

The tailcap springs are definitely not the same as the EA4 so I don't think its an overstock or reject Nitecore as some speculated.

Let's hope they cloned the rubber switch cover a little better. But if they didn't, you'll probably have about the same luck finding a replacemet boot from whoever made this one.

I’m assuming it has the same poor heatsinking the EA4 has, making it a poor buy IMO

Do you own an EA4?
I’ve done heat tests and it runs around 40c on turbo, compared to say my Roche 12 on high which runs 60c (950lum)
No expert but I would say the EA4 is on par with heat transfer , it’s comfortable to hold unlike the Roche.
I don’t have any other + 800 lum light to compare with so I’m curious.

Thats the point, its comfortable to hold because heat is not being transferred to the body as well as many other lights, making it more comfortable to hold, but causing lumen sag and reduced LED life (not that we care much about that)

Very true. Old-lumens did a tear down of the EA4 and commented on its poor heatsinking ability.

We’re waiting for the EA4 lookalike review… :smiley:

But follow up testing showed that the heat transfer to the head was actually perfectly adequate. With cooling to the light body there is no thermal sag, so it isn’t an issue.

To be honest it still looks the same to me as the original, although I can see where the springs are slightly different. I wouldn’t be surprised if they are made up of genuine overstock parts which have then been assembled without the Nitecore branding.

May be true but the jury is still out for many of us. It definitely could/should have been done better. BTW, Old-Lumens teardown was on the EA8 but a few people extrapolated the results and problems to the EA4 as well.

I counted the coils on my EA4 springs and compared them to the illustration. My EA4 had at least one extra coil but perhaps I shouldn't really conclude much from a minor difference. I agree they do look almost identical.

I'm curious as to why Nitecore would be dumping "overstock parts" for a light that is still in production though?

One of FT's forum staff, Geek, has confirmed the electronic switch but did not state if it was a single-stage momentary or the dual-stage like the EA4. I've asked him to check again and am waiting for his reply.

Old-Lumens did actually do a follow up teardown on an EA4 and confirmed the internals were the same design. There was quite a long discussion in the thread and another specific one on how adequate the heatsinking was. I think the general consensus was that ‘adequate’ was exactly what it was. Yes it could have been done quite a lot better. But functionally it was nothing to worry about, heat was transferred to the body as fast as the LED was producing it, the bottleneck in the heat transfer was not tighter than from the LED to the board itself.

I think Nitecore may be close to making a revision on the EA4, they are changing the switch material after so many user issues and may look to upgrade the emitter too. This might simply be parts for old stock which they wanted to clear without clogging up their own retail channels.

I remember when intl-outdoor had genuine unbranded but OEM Nitecore EZAAs on sale a while back (I picked up a couple), so it’s something that Nitecore has done before.
