Haikelite HT08 Mini?

Got mine today

Good copper DTP MPCPB, but not enough thermal paste IMHO

I removed the stock driver to make it DD only (only bursts with that kind of flashlight for me) and put an XP-L HI instead of stock HD

Compared with my FET driven Dedomed XP-L C8 :

No numbers, sorry I don’t have a luxmeter.

The form factor is nice, I love the fresnel lens much than an aspheric though the HT08 doesn’t collect as much light as my B158B aspheric zoomie.

HT08 on the left, B158B on the right (dedomed XP-L and DD) both with 30Q

Is it just me or are X3 his pictures not all appearing?

Same here.

So, it ‘stretches’ a really long way.
That means the lens has a long focal length.
That means you lose a lot of light when focussed.
It also means a tight narrow beam with a small projection of the LED.

I ordered one too, but it’s not in yet.

Fixed, sorry guys

Thanks for the photos X3. How’s the stock tint?

This is about 2 feet from green wall. As you zoom out they go away but are back when getting out to full zoom out.

And yes, you have to turn the head forever it seems like. This light sure seems like it should put out more lumens.

My only experience with zoomies is a Cometa….that I like.

Thanks for the pics, X3 & chooma. Just ordered one, with that DTP board, I just need to replace the stock driver with my extra BLF A6 and done.

Hope to post my review of the Haikelite HT08 on Thursday night (in theory).

Thank you for the pictures and information, X3 and chooma!

I wish HaikeLite would come up with a small/lightweight 18350 light.

Received my HT08 today…
Total design faillure… :person_facepalming:
When focussed only –30- 50 of the lens is used because the light from the LED goes through a narrow tube.
The focal distance of the fresnel lens is already very large, so even when 100% of the lens was used when focussed it would be a relatively small amount of light that would be focussed.

To solve this there has to be done some serious machining, and you’ll lose the ability to make a wide flood like you can with the stock set up, because you’ll have to open the head up by removing a considerable part of the threads inside the head.

And then the modes: High - strobe - SOS :person_facepalming:

$18 wasted…
…unless i succeed in modding it…

I set mine to Lo- Hi group 2.

UI:

5 half-click to select group (programming)

8 half-click to active or remove "mode memory function"

Group 1: single mode

Group 2: Low / High

Group 3: Low / Medium / High

Group 4: High / Strobe / SOS

Group 5: Moonlight / Low / Medium /High+Strobe+SOS

Wow, great programming UI… :person_facepalming:
I didn’t get a manual, 5 clicks and then what?
I hate this light right now…

[edit] Okay, it’s 3 modes (low - high mid - high) now…

Yes, a manual would be nice. Mine arrived in mode 1 - single mode.
My review is here: Review with X-ray Image: Haikelite HT08 Mini

I have one on the way……Is it really that horrible? :frowning:

Yes, only 30% (estimated) 50% of the lens is used when focussed.
Only the centre of the lens receives light form the LED when focussed.
I managed to get the driver into 3 modes though, so that’s okay now.

I wonder how does it compare with zoomies using aspherical lens.

Some measurements show that 50% of the lens is used when focussed.
That’s significantly better than 30% of course, but still only half of what it should be.

I hope to finish opening the inside of the head today so that 100% of the lens is used when focussed.

I did one very unscientific test but it proves what Jerommel is talking about.

Specs of my HT08:
Dedomed XPL led
Blf Fet+1 driver
Samsung 25R battery

I measured throw twice in a row with same battery one right after another. First test was with light assembled as intended to work, measured intensity was 45kcd.

Next i disassembled the light and took the lens in front of the light like this:

This way the lens will capture as much light as possible. This way the light gave intensity of 113kcd.

Well, there you go. :+1:
