Mmmm... many people holding iPhone nowadays. 100% made in China too. Most things we use today are made in China.

Instant water heater is less energy consuming than a storage heater.

I suggest not to do it. If aircon leak, then problematic. You should consider making one opposite the aircon.

Yes.

Hi, The 5A light point is likely to be measured in AC. The 1.2A that you have mentioned for LED strip is for DC AC 5A and and DC 5A is a different unit. A 5A lighting point is able to support a load of 1100W (220Vac x 5A) The LED strip for a 10m LED as you have mentioned is 144W (12Vdc x 12A) The point can easily support the load. Not to worry. A typical RGB LED strip that I have seen is consuming about 0.5A per meter when all RGB LED get lighted up. It is always better to use a higher wattage power supply for your LED strips.

$60 for the lamp is enough to buy LED downlight. There are also new energy saving PLC bulbs which cost $8++ each. Instant on, use 4 times less current, generate less heat, lower energy consumption, and longer lifespan. The best part is that they can be use on normal/old PLC lamp holder. It doesn't matter if you have the magnetic ballast inside your lamp housing. The power consumption is lower than conventional PLC lamps. You should see the demo at Havelock Road Blk 22; impressive.

You can try saveOne at Havelock Road Blk 22, or XinLong in Sim Lim Tower.

Wire door bell uses less energy. It is possible that a wireless version uses little energy too. It depends on the circuit design of the product. You can test it easily using a power meter. I never like those battery type of door bell which need battery replacement. Not so Eco friendly, I feel.

All incandescent lamp are dimmable. These includes chandelier/halogen bulbs. They are very energy consuming. You can easily save 800% energy by switching to LED lights or 400% using fluorescent lamps. Fluorescent and LED lights needs their special dimmer in order to dim the lights. There are also new design which allows them to be dim by conventional dimmable but they are more expensive.

I would recommend - saveOne at Havelock Road Blk 22 - or XinLong at Sim Lim Tower.

You can contact - Tay. HP: 9615 5334 Good professional plumber that solved difficult problem for my work office. I will probably not get any other plumber.

Of course not true.

I think it is a bit too expensive. You should seek for more alternative quote.

You will need these items for RGB LED strips. - RGB LED strip (about $25/m) - 12V power adaptor (range $12 to $30) - RGB color controller (about S$20) Most color controller supports up to 10m of RGB LED strips. You will need a booster if you need to connect longer than that. 12V power adaptor will depends on the length of your LED strips. A typical RGB strip requires about 12V 0.5A per meter. If you are running 5m RGB LED strip, you will be using 12V 2.5A. So you will need to get a minimum of 12V 3A adaptor. I would recommend a 12V 4A power adaptor or bigger rating. If you have at home a power adaptor 10-13V, you can also use them instead of throwing the adaptor away. Just ensure that the current is enough to power up your LED strips.

You can try visiting saveOne for LED lighting. The price is not so expensive; range from $30 to $70.

The cove lights looks good enough. Impressive. LED strip price range from $12 to $25 per meter depending on the type of strip. Smaller LED bulbs are generally less expensive as compare to a bigger brighter one. RGB colored LED are the most expensive type at about S$25/m The power adapter can easy cost $12 to $30 depending on the length/type of the strips you are getting. The LED strip uses 12V and the amount of current depends on the LED strip's length. The highest powered LED strips uses 0.5A per meter. 12V 2A typically supports about 2-3 meters 12V 3A typically supports about 3-5 meters 12V 6A typically supports about 5-10 meters Sim Lim Tower's LED strip looks more expensive than I thought.

Wow. $38 is near to a LED downlight... Actually, all the PLC downlight (G24 base) that I have seen uses magnetic ballast. Mainly the cost difference will be on the quality and material. Unless you change to a E27 lamp base, it is likely that you are using the old type of fluorescent technology. There is a new type of fluorescent tube with G24 base on the market that uses much less energy than a PLC lamp. It works like normal E27 energy saving bulb which are all instant on. The current is 4 times lower, which means that less heat will be generated. The lamps is integrated with electronics control, and is able to work with the old magnetic ballast into the PLC lamp. The tube cost less than S$10 each, and I think it will be a good alternative to LED lighting. If the $19 lamp and $38 looks the same, I will go for the $19 one.

Just pull them out. There is always a way to pull them out. Electrician will not be so stupid to seal them up.

Lumens is the total amount of light energy which is given off from the lighting. Regarding to Soichiro's comment on LED 1) LED nowadays are surprisingly bright. I have installed some low powered LED lamps now and is very satisfied compare to my old fluorescent. Lower energy, less heat, no ultraviolet and best of all long lifespan. 2) You can change the LED bulb if anyone of the little tiny bulb is damaged but it will take some effort. I am a electronic trained engineer; there is nothing that cannot be repaired. I agree it is not easy for a typical user. 3) LED is getting cheaper nowadays; in fact I brought mine for my bath room and toilet. Tha lamps cost only $30-40++ 4) Some LED lamps has integrated driver, some has external driver. External driver is easier to be repaired. All LED lamps that I have seen are flicker free. LED is unlike fluorescent where they have a flickering starter to start up the tube.

LED downlight has many different type; not necessary a spotlight type. There are many available model with disperse light and is even bright than normal PLC downlight. Try to choose a lower power LED downlight as it generate less heat compare to a high power LED downlight. You can differential by their appearance. High power LED lights tends to have metal casing or heatsink built-in. I have seen those LED downlight for homes, range from $30 to $60++ dollars. They are not really so expensive. China uses a lot of LED. I think they are leading the trend to bring down the LED cost.

Ya. I agree. CAT5e would be enough for 1000bps in our home. It is very easy to laid your own CAT cable. The cable, socket & the RJ45 crimper cost $100++. You can easily DIY, to save a lot of money. I have this website for your RJ45 color code http://siongboon.com/projects/2006-03-06_serial_communication/#Ethernet%20wiring

MR16 LED bulb is actually not that expensive. Those I saw range from S$16 to S$25. S$16 range is for those without the LED driver (transformer). With driver integrated into the bulb, it cost a few dollars more. With dimmable function, the bulb will be additional few dollar more.

T5 lighting is a newer fluorescent tube technology. T8 is a older long fluorescent tube technology that is still very common in Singapore. T8 tube commonly comes in 2ft, 3ft, 4ft. Tube diameter is 1" or 25.4mm T5 is a newer kind of tube with tube diameter 0.625" or 15.9mm. The length is similar at 2ft, 3ft, 4ft. Nowsaday, a lot of new homes uses T5 because - It is more energy efficient comparing to a T8 tube - It is smaller in size - It consume less energy than a T8 tube - It uses triphosphor tubes which gives off brighter luminance
