  5. hi totoro17 when u say 2-pin plug, do you mean the 2 pin power plug that plugs directly into the wall socket? The LEDs runs on 5-12 DC Volts so a step-down transformer and voltage regulator are needed at the very minimum. In other words, you will need an adaptor. You cannot plug the 240 VAC directly. Hope info helps!
  6. Hi guys Sorry for slow response as I only check this forum once a day. To answer some of the questions: 1. By the way, can the light penetrate deep enough to reach 2-and-a-half ft? Yes, it does. In fact, if there is no obstruction, the sand bed will be dimly lighted. It is interesting to see animals coming in and out of 'caves' built from liverocks. These 'caves' are complete darkness because the light doen't reach them and as the animals come out, it is like watching an actor coming into the limelight. Pretty interesting, well, at least for me :-) 2. Versions of moonlight Years ago, the first version was a single unit consisting of a box and 6 LEDs. These were cascadable; meaning you can diasy-chain more than 1 together. In the second version, the box was eliminate and I tried to produce something that stretches across the tank to give more coverage. It was called the Moonbar The 3rd version was called SlimMoon. Slimmer profile for smaller tanks. Only 1 feet version. Well, the last type are the ones I am currently doing; also with MoonBar. These come only in 2 sizes; 1 feet and 2 feet. For big tanks, I would recommend either A) Use a single 2 feet moonlight and make sure you select a zone in your tank that you want moonlight to cover. This will bring animals who loves moonlight to this zone and also allow a place for animals who prefer total darkness to hide. If you want to view your tank in its full glory even around 3 am without disturbing the inhibitants, you can try two or more units of 2 feet moonlights. Plan your zones carefully so it gives the best effect. Specs: 1 feet moonlight (suitable for 1 - 2 feet tanks) - 5 LEDS - Power Adaptor - Over-current protection - Sealed clear clasing Price: S$30 2 feet moonlight (suitable for 2 feet and above tanks) - 10 LEDS - Power Adaptor - Over-current protection - Sealed clear clasing Price: S$60 Since I am making these; I am open to other types of customisation such as putting more LEDs, mixing whites and blues LEDs, etc. Thanks for all the enquires and orders.
  7. Hi davwong & davidluvfishes You got PM Hi alanysw & gny moonlight is lower in intensity and consist mostly of visible blue light. Why blue? Because by the time the weak light of the moon reaches to the animals in the sea, it is blue in colour. Since we are only simulating the effects, we use blue directly instead of the pale white light of the moon. By definition, Actinic light is light which produces an identifiable or measurable change when it interacts with matter. It is usually achieve in an aquarium tank by an actinic fluorescent tube. It is higher in intensity compared moonlight and may consists of UV. Both try to achieve the blue chlorophyll absorption for zooxanthellae symbiosis to develop in the tank but moonlight is more suitable to be used in the night because of lower intensity and absence of UV. Also, the focus light of individual blue LEDs produces 'rippling effects' not present in tube-based actinic lamps. gny, if one LED is faulty, it need to be replaced. It is not feasible or even impossible to repair a burnt LED. Hope info helps! Thanks!
  8. Hi iantoh The 2 feet one I letting off is for 2 feet to 3 feet. The pictures I attached were 1 feet version. The 2 feet version is the same but longer. The moonlight I do is not using "the cylindrical acrylic tubing that is sold in sim lim" Mine is sealed so to prevent water from getting it. Each bright blue LED is protected by a quality resistor from over-current. It also comes with a power adaptor so it is just plug and play. Thanks! PS: It is sold but if any whould be interested, I can do new ones.
  9. Hi Someone named Edwin of 9XXX1827 ordered a moonlight but later went MIA. I tried repeated to contact him but he refused to respond. So, here I am, offering a brand new moonlight which was original S$60 at S$40. Details: - 10 bright blue LEDs - Encased in water-resistant casing - Comes with power adaptor. - New small form factor - Good for min 2 feet and above Anyone interested, please PM me. Thanks
  10. Hi I have PMed most of you. Here are some FAQs: (1) What is the purpose of moonstrip? Well, as I have mentioned, (i) you can watch your tank at night w/o disturbance to your animals. (ii) Less harsh transit from bright day to total darkness when you switch off your main lights at night. Creating a more natural environment at night. (iii) Moonlight suppose help to spawn corals and other night activities. (2) Does it consume a lot of power? No, it uses LEDs with minimal current consumption and yet produces bright light. (3) Any hidden costs for moonstrip? No, the moonstrip comes with its own power adaptor, ready to install and run. What you need is some double-sided tape or 2 hooks to hang off or stick at the side of the tank. (4) Why blue? This is because when light reaches to the corals at the bottom of the sea/ocean, most of the other colour (of other wavelengths) have already been absorbed by the medium (sea water, particles, etc.) Only blue reaches the bottom. (5) Does it produces 'ripple' effects? Yes, individual LEDs are miniature 'spot' lights that cast shadows and highlights. (6) Is it water-proof? Moonstrip is sealed by silicon/hot glue at both ends to prevent water from getting in. However, please do not submerge moonlight in the water! (7) How long does it take to make one? The process of preparing the circult board, soldering the components, wiring, sealing, procuring components, testing, etc. can be quite tedious. That is why I batch all the orders together. It may take me 1 -2 weeks to fullfill orders. Hope I have answer most of your questions! Thanks for your support. Please continue to PM or post your questions should you have any.
  11. Hi I have PMed all who are interested. Do allow me some time as response is overwhelming and I do not go online always.... To iantoh The voltage is regulated to 5-6 volts. The brightness is controlled by the amount of current passing thru it, via the resistor. Each LED is controlled by one resistor. The amount of light generated is bright enough to cast shifting shadows at the bottom of the tank but not too bright to light up the whole place. This is intended as we are simulating moonlight at the bottom of the ocean/sea. By the time the moonlight reaches to the animals, it is generally dark blue in colour. The exact wavelength depends on many many factors, including the depth, the composition of the sea water, cloudyness, and the moon itself. To jem Thanks for pointing out. I did not measure the exact wavelength but I did notice corals responding to it. In an artificial environment such as a home aquarium, we use a variety of modern technology equipment such as skimmers, wave generators, MH, chiller to mimic nature, moonlight is just another one of them. It encourages: (a) 24/7 viewing of your tank ( Simulate night activites instead of total darkness. E.g. Corals Spawning, etc. maybe other activities we yet understand or discover © A more 'gentle' transition between 'day' and 'night' without sudden switch off of MH or other 'Day' lights. Hope I answer all the quiries. Thanks!

  13. Some pictures of my 'old' moonlights:
  14. Hi guys I have new moonlights that cater for both nano and bigger tanks. Like my old version standard moonlight and slim-moon, the new moonstrip has a side profile of only 1cm x 1 cm. It features super bright blue LEDs, all protected from over current by resistors. Sealed at both ends for water-proofing. Comes with its power adaptor ready to be used. There are 2 versions, 1 feet and 2 feet long. There is also a special Christmas version to really make your animals party. Will describe more further down. Here are the pictures: My old 1 feet nano under the moonlight: Specs: 1 feet MoonStrip - 5 Bright Blue LED - Current Protected - Sealed at both ends - AC Power Adaptor 2 feet MoonStrip - 10 Bright Blue LED - Current Protected - Sealed at both ends - AC Power Adaptor Mounting options include double-sided tape, hooks, glue, etc. almost anything as it light weight. Can be used with a timer to automatically switch it on 5 mins before the main lights turned off. Now you can start your NightWatch :-) Interested, pls. PM me. Thanks!
