GT70vn with 70.2 SD matches the GT with XHP35 HI 1Mcd intensity but with ~3 times the output!

Probably 3 times the battery sag too. Sure must be impressive the first couple of minutes tho, not to mention the lower cost! Very tempting.

Re: BLF GT70vn - Budget Searchlight

Is it worth it or should I save a bit more for gtvn2?

Twice the money but for me its twice the light. I am also not really into the yellow shave dome tint of the corona althought that is not too bad outdoor at distance.

MT35+ VS GT70vnSD + GTvn90 V2




1.2Mcd VS 1Mcd VS 2.2Mcd

2000Lumen VS 6500Lumen VS 5500Lumen

$270 VS $335 VS $700




All considered which one would you prefer?

Which makes me wonder how the camera was setup..

Mine was white leaning towards blue in stock form but now that it is dedomed it is just perfect with a barely noticeable yellow/green corona.

I wonder if there is just a massive tint variation (shouldn't be as they are claimed to be 1A emitters, not simply a random A/B/C/D lucky dip) or if in fact the GT70 dedomed version looks much whiter and the CFT90 much bluer in real life.

Compared to my TN40Svn 5000K it just looks cool white. Also, unless you are super keen on having a massive light (and I mean MASSSSSSIVE) or plan to dedome it, then I would go with the TN40Svn as there is seriously little difference between the two. Even when dedomed, the GT70 is not what I consider a major upgrade over the TN40Svn. That Thrunite is just a monster after Vinh did his thing but the GT70 does have more thermal mass so should run at higher levels for longer and the 8 cells VS 4 cells does seem to offer greater runtime but that should be expected.


EDIT: yeah, I just had another look and if you compare the 6500K XHP35 HI BLF GT to the CFT90 version, you really see how blue the CFT90 appears. That or the XHP was mislabelled and is a 4000K NW version....??

Production GT is 4000k XHP35 HI. Only pre-production review samples were 6500k. I had Vinh put 4 of them in my TN40 and the tint is pretty decent.

I thought the "cold white" option they had on their website for the XHP35 HI GT's was 6000-6500K - is it meant to be neutral and warm or is that a relatively new option some people wont know about?

Possibly a relatively new option, though I haven't heard any news of it. What site did you find the option on?
