Lightbulb TV Cabinet LED Lighting Transformer

Dear All,

Good day to everyone! This is my first post indeed, so please excuse me if there is any gaps; especially I am unable to post URL as my post count is less than 20 (could someone assist me to post?)

I am doing LED lighting for my new apartment TV Cabinet. I would like to know what should be the LED driver/transformer/power supply rating as in the watt, volt and ampere.

Below are some information to :-

1. Connection of the strips/LED to power supply will be in parallel.

2. LED Strip spec
• Supply voltage: DC 12V
• LED quantity: 60LED/m, 300 LEDs
• LED Type: High Quality 5050 SMD LED, high intensity and reliability.
• Power: 0.24w/led ; 60w/300leds;
• Working Current/5Meter: 5A
• Lumens: 144lm/m (12lm/Chip)

3. Spotlight spec - IKEA Vaxmyra LED Spotlight
Power: 1.4 W

Do let me know if you need any more information.

Thank you and looking forward for the reply.

Regards,
Kumaran

First I would look to see what power the Ikea lights need. Also try to find out their wattage. Hopefully it takes 12 VDC like your strip lights.

As for the power supply you need it has to be 12 VDC as that's what your strip lights need. Then add up the wattage of everything you want to power. Then I'd add 25-50% and get a power supply of that wattage. Amperage is simply another way of expressing wattage. Watts divided by voltage gives you the amperage. For example 100 watts at 12 vols is 8.3 amps (100 watts /12 volts =8.3 amps)

Looks like the lights are mismatched.
Spotlights need 24 volts while the strips need 12.

Dear Pilot Dane,

Thanks for the reply.

Will it spoil the strip if I use LED driver with more than 12V?

Dear manden,

Thanks for your reply.

You are right, IKEA recommending below power supply for the spotlight.
https://www.ikea.com/my/en/p/an****a...hite-70405865/

Let's say now I get LED driver with output 24VDC and hook both strips and spotlights to it.
I believe it will not cause any issue to the spotlight but how about the strips? Will it spoil the strip because only 12VDC required for the strips?

Regards,
Kumaran

I would not run 12 volt LED's at 24 volts.

Have you bought any of this stuff?

The reason I ask is that it is a TV cabinet so being able to dim the lighting would be advantageous.
Then you have flexibility to change it depending on what you are watching and the ambient light.


Also it looks like many folks like to be able to control the color but I do not have this type of setup so cannot comment on it.

Dear manden,

Then I might need to power the strips and spotlights separately.

Nope, I am yet to buy any of the stuffs since I have no idea which power supply to buy.
Yeah, dimmable is another feature I would like to have due to the benefits as you mentioned.

Yes I would power them separately as you will probably want to control them separately.

Hi, seems like a mish mash of stuff for a TV cabinet, have you checked sites out for this specific project? I just set up back lighting and I used a product from Govee Home, although their CS isnít the best I did get it figured out , you can use an App on your phone etc. if you like.
