Review: Haikelite SC01

Thanks again for the review, can I ask you a favor? Could you show a photo whit the Haikelite SC01 next to the Ultrafire C8 and the Convoy S2 +? To get a better idea of the size, thank you in advance, greetings.

Sure no problem at all.

here you go. :partying_face:
i also threw in 18650.

Thank you very much! I hope receive mine soon, looks great.

Does it come with an adapter for an 18650 battery?

Nope it doesn’t, but with the adapter 18650 is fine in this flashlight.

I just received my SC01, and a bit disappointed in the turbo lumens and throw.

I measured the modes as follows:

Mode Spec lumens Measured tail amps

low-low 20 48 0.10A

low 200 255 0.46A

med 500 615 1.28A

hi 1,000 1,074 2.69A

turbo 2,000 1,639 5.65A

Turbo throw: 60 kcd (measured at 5m), 490 meters

This light is a 40.1 mm diameter head, and reflector I.D. of 31.0 mm. An Eagle Eye or BLF X6 has an I.D. of 29.0 mm, so it's a little bigger which is good, but puts it in about the same class.

I would say the lumens in turbo is about expected, compared to hi mode - the higher the amps, the lower the efficiency of amps to lumens. Also I think the 60 kcd is expected for a reflector of this size,and these amps drawn from a single cell with a XPH35 HI.

To get 92 kcd from mine, the lumens would have to be about 2,400, 50% better than what I'm getting. The optics in mine looks good: nice AR lens, reflector looks perfect, LED is aligned well and seems reflowed well. I can't see anything wrong, but who knows...

For the low turbo lumens issue, going from hi to turbo and double the lumens, you have to more than double the drawn amps by quite a bit. 2.7A to 5.7A is not enough to double the lumens. It would need over 6A easy, maybe ~6.5A would get you close. You can see the delta from med to hi in amps vs. lumens, and at higher amps, the ratio of amps to lumens has to be even higher.

this is the draw i got from the tail.

— Low Low—20 lumens (0.133A)
— Low —-200 Lumens (0.527A)
— Mid —500 Lumens (1.44A)
— High—1000 Lumens (3A)
— Hidden Turbo—2000 Lumens (5A-6A) 6.05A at the start.

i am not sure how comparable your result to mine, but my Luxmeter could read higher.
I have no way of measuring Lumens other than using relative ceiling bounce but then again the result is not comparable to others.

This are the relative lumens output on some of my lights. it is below MT01 and MT02 and above BLF A6 but i have no idea how much Lumens my BLF A6 made. But on thing a agree on is that SC01 doesnt output 2000Lumens.

This I guess makes me feel a little better (i think), because just from purely looking at the difference when I would go from High to Turbo, it was very subtle, so it made me doubt that it was actually 2k lumens (dont have a light meter yet). When compared to the KDlitker, output seems to be almost identical. Again, this is me just looking at the output using my eyes so very subjective.

I recently bought an SC01. As has been described by one or two others, I encountered a switch/driver issue which requires multiple button presses for the light to turn on. Within a few days of purchase, I emailed Haikelite, and they ignored my email. I sent a follow up, which they eventually responded to but did not offer any remedy (they did ask if I would be technically able to replace the driver, but did not actually offer to send me one). Follow up emails were also not responded to. I cannot think of any reason why I would buy a Haikelite product in the future, since the company does not seem interested in resolving customer issues and is horrible about responding to email.

Which is which?

SC01 (left) vs D1s (right)

Ohhh - had to widen my screen. Pics were vertically stacked, not next to each other. Once widened, makes a lot more sense

Looks like CW vs NW and the smaller reflector D1 has a tighter beam because of the XPH HI.

Mine only throws a fraction of yours, 60 kcd vs. 92 kcd, so yours is really tweaked, or mine is pathetic, both factory stock. These things do seem to happen though from HL - I've seen it with the MT07 and MT03's.

Even 60 kcd vs. 43 kcd, the SC01 should easily beat it, but doesn't seem that way in the pics, the last shot specially. It's like the lights are reversed or, the D1 does 80 kcd and the SC01 does 40-50 kcd -- the pictures don't make sense against the specs.

Wonder if coaox tested kcd, or maybe modded up his D1.

I think that is a beams shot of the D1s, which isn’t released yet, but I believe freeme has a sample. It’s a C8 sized thrower, not a pocket thrower like the regular D1.

The D1 is released - Hank has 159 in stock, taking orders, and spec'd at 43 kcd in his D1 listing here. The beamshots are from BLFer: coaoxx.

I have a SC01 and think the reflector is more like the size of a Eagle Eye X6 - Haikelite specs the head diameter at 45.5 mm, but that's not at the bezel. At the bezel it's closer to 40 mm. But there's also a big difference between an XPL HI and XHP35 HI - the XPL HI should have a tighter beam, but that's offset because of the smaller reflector.

It's confusing, but based on specs for throw, I can't explain those beamshots.

No, there is the D1, which is released, and the D1s, an upcoming C8-sized light that is supposed to push 120 kcd. The D1s is not released yet, but several people, including freeme and Toy Keeper, have samples.

Those are not mine. I am just a keen buyer like the rest of us. TK said she is working on D1s review.

Sorry, since you were posting the pics, figured you were one of the ones with a per-project sample.

D1s as in plural or typo - my bad . Wow, this is confusing....

Here’s an update regarding my experience with Haikelite after having bought an SC01 having a faulty switch/driver. After a bit of back-and-forth messaging on this forum with Haikelite, they agreed to send me a new head for the SC01, which arrived today and resolved my issue. :slight_smile:
