  1. Customer service was terrible in the past but since Wolfgang Tick is the new owner it became definitely much better. The Subtronic 270 should be comparable with the Hartenberger regarding light output. But I dont own the 270 and have no experience with it. Gesendet von meinem LG-H525n mit Tapatalk
  2. I have two Subtronic pro 160 and 2 Hartenberger 250. For travels, the Hartenbergers are by far too heavy: Over water, one of them is heavier than both Subtronics. Furthermore, in manual mode even the -5 setting of the Hartenberger is often by far too strong. Advantage of the hartenberger: it is very probable that you will not need any support. They just do their job. Furthermore, they have pilot lights that are usable, the ones from Subtronic do not deserve the term "light", it is just one single weak LED, their intensity are equal to half a candle light. Hartenbergers are +- neutral under water, but still bulky (I would not like to dive with 2 of them in strong current). Regarding size, the Subtronic Nova (270) is in between the Subtronic 160 and the Hartenberger 250. I think there is absolutely no reason to take the Hartenberger 625. It is, furthermore, not even fast enough for preflahes and you would have to work in manual mode only. With a TTL converter, you can use the Subtronics or the Hartenberger 250 in TTL mode which works perfectly for macro (reduce the fash intensity in camera settins when using Hartenberger in TTL mode sine the TTL converter I own is made for weaker flashes). The Subtronics are a pain in the ass during night dives in manual mode because you cannot read the back Panel du to lack of light there. Hartenberger works great, the buttons have a built-in light. Although Subtronic claims 116 degrees light angle and Hartenberger only 90, they are absolutely comparable. But as mentioned, the Hartenberger is much stronger, and the difference is for sure more than 160 vs 250 Ws. Therefore, either the Subtronic has less than 160 Ws or the Hartenberger has more than 250 Ws. Advantages on both sides, it absolutely depends on your needs which flash works best for you. Hope this helps a bit. Jens
  3. Come on, google is your friend. Sorry. Only € 13,90 https://www.akkuteile.de/lithium-ionen-akkus/32650/trustfire/trustfire-32650-6000mah-3-7v-geschuetzte-li-ion-akku/a-100707/
  4. You recommend here a torch that obviously causes lots of problems, just because the company has a good customer service? I would rather prefer a reliable torch. I am currently using the F.I.T. 2400 LED WSR as well as the UV version, and in my 30 years of diving I never had a better torch. Ever. :-) Stronger light output, longer burn time, much broader flood than the Sola, 100% anodized aluminium, user exchangable battery (6 Ah Lithum 32650; spare battery = 15 Euro). WSR version has both flood AND spot, therfore you can use it as normal diving torch as well. Regards; Jens
  5. For WA, a warm colored flash is an advantage because you get a very nice blue water in the background (the auto white balance corrects the warm colors from the flash which leeds to cold blueish colors of the background). Hovever, I do not see a reason for a special flash color in macro photography, because you (or the camera in "auto" mode) can correct the color with the white balance setting.
  6. Can you explain what the "20 hours autonomy" and "charging by USB" is good for? I thought the RSU units receive the electrical power from the strobe?
  7. Did you consider these ones?: http://www.fun-in.com.tw/oc/index.php?route=product/product&product_id=1592 A review of the 2400 Lumen version can be found here: http://www.fun-in.com.tw/oc/index.php?route=product/product&product_id=1592 Jens
  8. That one?: http://www.idealo.de/preisvergleich/OffersOfProduct/730891_-64250-hlx-esb-20w-6v-osram.html
  9. Thx for the review. I am considering to get the UV-Version (has both UV and purple LEDs: http://www.fun-in.com.tw/oc/index.php?route=product/product&product_id=1689 ) of this light. Is there anyone who compared the light output with the Light & Motion Sola Photo 1200? Since the angle of the light output is quite large (120 °), I wonder if this light might not be a good choice for normal (night) dives. Any comment on that? Thanks, Jens
  10. Yes, it is an Amphiprion polymnus. An excellent book on Anemonefishes ist Daphne Fautins, unfortunately no new one to buy at the moment: http://www.amazon.com/Anemone-Fishes-Their...s/dp/0730983927 You can find an online-Version here: http://www.nhm.ku.edu/inverts/ebooks/intro.html Regards, Jens
  11. Hi Robert, one of the flashes is brand new and was never in the water, both look brand new. 2 x Subtronic pro 160 2 x Strobe arm (=battery) 1,3 AH 2 x quick charger 2 x Neopren protection (2 covers: general one and front cover) 2 x Nikonos wire 1 x Splitter to connect flash to one plut at your housing It is the ISR (Intellisync ready) version of the flash, no TTL converter built-in. € 1900,- + shipping
  12. I have a pair of Subtronic 160 here, both bought in 2011, therefore still under warranty.
  13. Hello, thx for this great thread which will help me to remove upcoming scratches (I expent them sooner or later :-) ) from my acrylic zoom dome port. I just tried to buy a kit of N78-1 micro mesh here in Austria, but unfortunately, the responsible distributor is in Swizerland and offered it to me for 65 Euro (95 USD) + 45 Euro (65 USD) for shipping!! He definitely said that I have to pay the shipping from US to swizerland AND from switzerland to Austria. LOL. Are there any comparable products which can be bought in Europe for a fair price? Any help is very appreciated, Jens
