Introduction: Replacing Your Dim Kitchen Hood LEDs
When we remodeled our house the kitchen was designed as our center piece. We enjoy having company over and our kitchen always ended up being where everyone hung out. I’m sure many people can relate.
Being that I’m the cook of the family, I’d always have my back to our guests. So now that I had a chance to start from scratch, I designed the layout placing the stove and oven in a deep island of our open-concept kitchen, with an extracting hood directly above the stove.
After many days researching the right hood that met our style and budget we decided on this one. It was very straightforward to install and looked great in my kitchen!
Unfortunately, there were a couple downsides. Since the hood was 36” wide, it cast a shadow over my stovetop and the included LED lights were very dim and had a blue tint, which were very different from the temperature of the rest of the bulbs in my house.
That’s when my mission began. I searched everywhere for replacement bulbs. Google, Chinatown, China (via Google) and even contacted the manufacturer. After almost a year after finishing my house and giving up, I decided to give it one more shot. This time I put on my DIY hat and took the fixture apart to find a very simple circuit. And after searching AliExpress.com, I found a perfect replacement. In my case I needed exactly 32mm, so the 3W was perfect. I just needed to wait about a month for them to arrive from China. But, for the price it was worth it.. I even have 6 extra just in case on burns out or I come up with another project.
This was a fairly quick project considering I had all of the tools at hand. Each light fixture took me approximately 5 minutes each from start to finish. I then took the opportunity to clean the grates since I had them down.. and they needed it.
Step 1: Open Fixture
After removing the LED fixture from the hood, I removed the 4 screws from the back which exposed the panel of DIP (Dual In-line Package) LEDs.
Step 2: Out With the Old...
The LED circuit just popped right out revealing the PCB board which was connected to a positive and negative lead. There was barely and solder, so with a touch of my iron the wires came loose.
Step 3: In With the New
This next part was actually easier than I expected. It was as if the new PCBs were made for the fixtures. With the help of my helping hands, I got the leads soldered on and placed the PCB into position.
I then placed the cover back on and screwed in the 4 screws.
Step 4: Finished and Happy With My New Lights
Getting the fixtures back in their spots was satisfying. These new LEDs are really bright making it possible to see what I’m cooking.
In the final picture, my ceiling lights are off and I only have the hood lights on. I’m very impressed with the brightness of these 3W LEDs!
Thanks for following along with me and I hope this helps someone somewhere.

Thanks for the well done article. Great pics and way to think outside the box..I just used the same technique after discovering this slightly old article. Our hood is the same as in the article. I ordered the 32 mm 3w chips from the same company, received 10, only needed four, very inexpensive, think less than $8. Soldered per article and installed, very happy with the increased brightness. My improvement is only a couple days old, so far so good.
My question, after 4 years ChachiC ( if you're still around) have you noticed any early degradation? Not sure if these chips are up to the task of bearing the heat and humidity of cooking but guess I'll find out :)
Are you still happy?
Question 4 years ago on Step 3
Thank you for sharing your idea and the detailed instruction for this! On my hood and the LED housing (whcih is similar to yours, but has 9 LED's instead of 12), there are labels that say it should be less than 2W. Did you have similar labels? I am curious to know if you had the same limit and if the circuit could last for a while with 3W LEDs.

I decided to not risk and ordered 2W ones:

They were not a perfect fit, but the fixture and the four screws could hold it in place. I am very happy with the final result. Much brighter than the original bluish LEDs. Those were in fact 0.7W each, the new ones are ~2W each. Here is a comparison of the brightness. Thank you ChachiC

Wow, definitely a significant difference! I didn’t see any labels on mine, but they’re still going. Even if they fail ina a year or so, the set that I bought came with 10 circuits and I only needed 4.. so I have backups.
