After extensive research I came to conclusion that unprotected NCR18650GA are the best cells available for use in Zebralights and bought 10 of them.
I just received my H600w MKIII and noticed that the only marking on it is CE. ZL doesn't have model #s on their headlamps? My SC600w MKIII HI and SC5w both have the model #s. Mainly just curious.
My Nitecore protected 3400 18650 is a very tight fit going in the tube and a bit of a hassle to remove. Can both protected and unprotected cells be used?
The light output compares favorably to my SC600w MKIII HI. The only other lights I own are the two versions of the Nitecore HC30. I do like the Zebralight but the Nitecores at $30 less seem like a much better deal. Not sure I see the quality difference with the ZL but I'm new to these lights and need to use the ZL headlamp more to see if I notice a bigger improvement over the Nitecores. Maybe I had my expectations raised too much from the SC5w and SC600w MKIII HI, which to me are amazing lights.
Has anyone gotten their H603w yet, how do you like it so far?
On a side note, i was trying to find an 18650 tail light, and this little headlight will mount neatly to my seatpost, with a red ping pong ball for a filter. H600 ordered. 1300 lumen strobe. Problem solved. Hopefully drivers won't have a stroke and run me over lol, that would totally defeat the purpose.
I just want to share my 2c regarding XHP35-powered Zebra MK3s
I don't own any of them, but I'd advice against purchasing one.
First off, it seems that SC600 in its MK3 continuation has shorter shaft which makes it impossible to insert protected cells.
That's at least what people have been complaining in the respective thread.
Secondly, XHP35 is a 12V chip, rather unsuitable for single-18650 flashlight. Even Zebra cannot bend industry standards, which is at best 90% step-up conversion efficiency.
As the lm/W figures for XM-L2 are pretty much the same, it's clear XHP35 runs at higher current = more heat produced at 1100lm for neutral white.
The SC600 thread mentioned current ramp-up between generations at about 2A (MK2 - 3A, MK3 - 5A), which seems just about correct.
Given the numbers that's 5W more to be dissipated by passive means.
It's also unclear how these XHP's are driven. Low frequency (<300Hz) PWM strobing is not entirely out of question (something that makes LED flashlights impossible to use).
Bottom line, get MK2.
I don't accuse ZL of using PWM in that sentence, but since H600w MK2 does have high frequency >50kHz PWM, there's a possibility this frequency was lowered to meet the demands of switching step-up transformer, which could leak some of its switching current to the LED in form of IMD as well, if improperly filtered.Zebralight has never used PWM in any of its lights, and now without any evidence you accuse them of using PWM, and then back that up by saying "it's not entirely out of the question"?
I never said I don't have a ZL lamp. I stated I don't own any MK3 lamp made by ZL.I don't see what reason you have to allege that ZL is using PWM, and you admit that you don't have one.
I hope that what I say in the future won't be twisted to prove contradictory points and subjectively assessed without evidence.I hope that your future contributions to the forum will be less inflammatory and stay closer to the facts.
