china post is taking a long time to deliver my sc600w. It was shipped on the 24th... still not here. Unforunately I find china post and hong kong post take longer at this time of the year :(
I'd say there is a hint of green in mine at the lower output levels (anything not H1 or H2). I'm quite sensitive to green and I wouldn't say that it is bothersome. The tenedency towards a green tint is a side effect of current regulation (no PWM). (If you ask me to explain it further I wouldn't be able to. I'm just regurgitating.)
Wow. I had been waiting on the light to come off of back order. Last night, it did. So, since I had a good Christmas, I jumped on it. Checked it today (after getting shipping information), back on back order. That was fast!
Got the light today. I would put the LED at 4000K as it is the warmest neutral LED I own. Only slightly warmer than the T5 4B that I have in my Spark SL6, which is fine as it masks the tint shift from the hot spot to the spill. The tint is wonderful.
Another thing, every picture I have seen of this light, they just have a bump for the positive contact. I actually have a spring on the positive pole meaning I can use any 18650. This light does EVERYTHING I want (strobe, high output on high, really low low and uses an 18650).
The quality of the light is amazing too. The switch is tight, the machining is awesome and the knurling is REALLY good. Also, being able to get to all modes from off (including low without blinding myself) is REALLY freaking nice.
This is my first Zebralight but it definitely isn't my last.
I did a runtime test yesterday just to satisfy my curiosity so I figure I'll post it here since this is the only SC600 thread. :) ZL claims 2 hours on on H1 (highest high with 5 minute stepdown) on a 2900 mAh cell. The only other runtime test I saw was by selfbuilt and the cell he used was 2200 mAh. I wanted to see what it would do with a Panasonic 3100mAh cell.
The light ran 2:08:47 to 50% of initial output. So Zebralight seems to be accurate, and I'd guess that the 500 lumen H2 mode would likely run 2:20 or more.
Also I wanted to point out that current production models now have a spring for a positive contact, so flat top (or recessed top) cells are not an issue.
