  1. Hope the A. chrysopterus in LCK still ard till I'm back this weekend...... JC
  2. Its not recommended cost the efficiency is really low and high changes of heating up the LED. Thus shorter life. I'll suggest u go for constant driver. U can check with sherman if he still have those AC-DC constant driver from Meanwell, these save u the needs to get a AC-DC converter. Cheers JC
  3. Is that a Amphiprion Chrysopterus? Any idea the price? Saw many conspic angel in HK too but nvr ask the price. Cheers JC
  4. Are u still going to do the resistor method and not constant driver? Regardless of resistor or constant driver, u need to have dc power. Thus any power convertor will do as long as the output voltage and current meets ur application. Cheers JC
  5. No. U can't. These 3W LED need 3.6volt each. Thus for 6 in a series, u know at least 24volt (thks Sherman for the correction). Unless, u plan to do it with 3 LED in each string. And have 8 series in parallel. JC
  6. I'm not expert either. The clarkii complex are one of the biggest complex with many of them look very similar. Actually, if we look closely to the pix you posted, the tail fin does seems to have the distinct dark rays that differential the A. fuscocaudatus. Din look hard enough earlier. lol I'm training myself now to hopefully able to distinguish the various species from pix. Thus this thread has been a great training ground. Cheers JC
  7. A three string of 6 3W LED on parrallel, ur buckpuck will need to be providing 2.1A and 18vdc. When in parallel config, the current are divided and voltage is remains the same. The voltage needed is the sum of the total LED voltage in a single string. Hope this helps. Cheers JC
  8. It will depend on the voltage instead. Generally, a buckpuck can support up to a series of 6 3W LED. Do go through the evil66 Ultimate guide if have not. http://www.nano-reef.com/forums/index.php?showtopic=186982 Cheers JC
  9. Dun have a specific thread on it, u can search for arduino on the lighting section. http://www.nano-reef.com/forums/index.php?...lite=%2BArduino Cheers JC
  10. ya, i agree. A. fuscocaudatus has a dark central area at its tail base, with dark longitudinal streaks separated by lighter areas radiating from it (look like dark rays on its tail fin). But A. chrysogaster should have white border on its soft dorsal fin and on top of the caudal fins with is not seen in this pix. Imo, it look abit like the A. Tricinctus Cheers JC
  11. For dimming, what the guys in nano-tank forum are doing is using Arduino to control the dimming effect. Cheers JC
  12. Bro, juz compare the lux at 700mA. These china made LED can only provide >90lms with 700mA. Those from SSC, Cree and the one from japan only need 350mA for the same lux. Cheers JC
  13. Hi bro, i'll think a commercial high power led driver will be easier and they dun cost alot nowsday. If u are a diy kind of person, u might want to try something like this. http://www.instructables.com/id/Circuits-f...gh-Power-LED_s/ Btw, I checked quite a few china and taiwan high power led. Although they are at least 25% cheaper, they are half the effectiveness. Cheers JC
  14. Just saw a few Amphiprion Nigripes in HK LFS. They look so lovely with the "black boots". Are they common in Singapore cos I seldom going LFSing recently. Cheers JC
  15. Any pix of the tank and stand? Tks JC
  16. Nice. Will try them out once my tank are ready. JC
  17. Btw, have u been seeing A. sandaracinos been avail anywhere? Cheers JC
  18. Bro, have u attempted breeding the A. chrysopterus with A. sandaracinos since their off spring might give u A. leucokranos? Cheers JC
  19. Nice. Care to share your setup? Cheers JC

    How to Make

    Bro, read this. I'm using the same to test my LEDs. http://www.instructables.com/id/Converting...ly-to-a-really/ Cheers JC
  21. Can I know how long u owned the black pair? Cheers JC
