1 - How tall are the LED's? I am assuming that they are 1/2" tall.2 - Can I obtain additonal transformers separately?

Digital display of numbers are 3/8" high.They only supply 1 x-former so contact the mfr for this info.The display dimensions are; Bezel; 2 3/4" x 1 3/8". Panel cutout 2 3/8" x 1 7/16"

The bulbs are .075 watts. They are LED and do not appear to be removeable. Since each bulb is less than one watt compared to my old sidewalk light system- , Malibu, (used to be either 4 or 7 watt bubs) I can add more lights on the same string to the LED transformer. But now all my new lights need to be LED- I understand it cannot be mix and match -LED and standard bulbs. I hope this helped. I had to get a lot of answers from different sources - electricians and lighting experts on what I needed to do.

Let's see, 20x10w = 200w; the transformers are rated 150 w. If these were real transformers, there would be no issue. BUT ! These are "electronic" transformers; I am not sure how they work (or why !) but they seem to be very sensitive to being matched capacity to load. Thus, you might be better off with 2 x 100w transformers. Note too, that these are sold as "12v" transformers; the reality is they are 11 volts +/- , I think, 10%. 9.6 volts is " in spec" ! Halogen lamps are designed for 12-14 volts, 11 volts results in noticeably dim lights.

Sorry for the delay Daniel. It depends on the type of LED strip. Most reels or strips are 16' If the strip has 300 LEDs its usually a 30 watt strip. If they are high intensity or double LEDs then they are 60 watts which is the maximum of this transformer. so If its 30 watts then 32', if high intensity then 16'. It's all about the watts!

Hello Simon. I have just ordered some of these units from Amazon USA to be shipped for my home use in Singapore also. May I please ask how your experience has been with them, what transformer you use and where you purchased these transformers?

Best to contact the manufacturer. Some transformers need more of a load than the LEDs provide. We bought 2 different sets of cable lights. One transformer could use them the other could not.

If your taking about LED light strips, first you need to know what the Amp draw is for the lights. That can vary based on the number of lights / ft and the kind of lights. The last ones I used had 3/4" space between lights and were rated at .7 watts / ft. The next thing you need to know is the specs on the transformers. The transformers that I used supplied 2000 mA or 2 amps. One thing we learn in basic electricity is that 1 watt = 1 volt x 1 amp. So, that means each 16' strip of lights requires x 16 x .7 or 11.2 watts. Therefore, since V x A = W 12v x 2 amps = 24 watts. That means that the transformers that I selected will only supply 24 watts each. Conclusion based on my transformers they would only power 2 strips each. So Alicia, if the light strips are close to each other, I would look for a transformer that could produce higher amps. and only need 1 or 2 transformers.

They are minimum 5 inches, if I remember right. Kit includes wires, electrodes, led bulbs...

Answer to your question they are 1 1/8" long..from top to bottom including the wire leads..X 1/2" wide..These are the ones i received..As far as the lumens go i have no way to measure them..but are very bright for my use..

I'm sorry but I cannot answer this question for sure. We no longer have the packaging that it came inBut I am thinking that once the LED goes out, it's done. Maybe that is why they are fairly inexpensive.

It depends on the length/number of LEDs in the strip, and transformer size. None of the Amazon sets matched my needs. I called the company and they designed what I needed, told me how many transformers to use, and gave me a better price.

I stripped back about 1/8" and soldered wires directly to the pads. You can also solder stiff square wire so you can use the plugs available for them. Now if your asking how long a strip of LEDs you can use. It really does not make a difference providing you have the proper power source and do not exceed the specifications of these led's.

The LED chips on mine are clear potted into the white plastic base. The pwr leads seem to be molded into the bases also. That said, ultimately the mfg should specify if they are indeed water rated- resistant or proof? Sorry I cant offer more info, it didn't seem like these had a data sheet when I received mine. What I can tell you is on 13VDC SLA battery these are rather bright, two modules (6 LED chips) will moderately light up a smallish dark room. They should do reasonable well for sign backlighting given enough modules are used. Their CRI I would guess to be in the high 70's -low 80's as they seem to look to be 7000plusK.

Well, nothing scientific, but they are blindingly bright. I can not look at the leds withput it hurting my eyes. The actual brightness will vary depending on the voltage applied. I don't know of anyone who had done an actual measurement.

I used a 12 volt 1 amp or greater DC transformer from the Goodwill store ($1.99); works well. LEDs are polarized so you have to get the + and - side correct or it won't work.9 Volts will also work; must be DC.

I know that the seller has different lumens available depending on your needs. If you contact seller you can get all your questions answered. Seller configured my LED's to my personal needs, so they are not a one size fits all application.

I believe they are about 1/8". But just to let you know the display does not come with instructions or wiring diagrams. I was very unhappy with it, it took a lot of research to find out how it hooked up. I would find a different maker if I were you.
