Review: Perfect in My Replica Oxygen Destroyer from 1954's Godzilla - I used these for a 3D print of my son's Christmas gift: an oxygen destroyer replica from 1954's 𝘎𝘰𝘥𝘻𝘪𝘭𝘭𝘢. I'm very, very pleased with the outcome. The aluminum material seems to be of decent quality. I was able to secure the LED's using some rosin/flux paste and silver solder. I added some CPU thermal paste to help transfer heat from the LED to the heatsink. In testing, I was unable to get the temp of the heatsink above 89°F, which is fantastic! The quantity of 25 was far more than reasonable for the price and shipping was very fast. I would absolutely recommend these to anyone running higher wattage (1/3/5) LED's.

### ⭐⭐⭐⭐⭐ Perfect in My Replica Oxygen Destroyer from 1954's Godzilla
*by C***U on May 20, 2025*

I used these for a 3D print of my son's Christmas gift: an oxygen destroyer replica from 1954's 𝘎𝘰𝘥𝘻𝘪𝘭𝘭𝘢. I'm very, very pleased with the outcome. The aluminum material seems to be of decent quality.

### ⭐⭐⭐⭐⭐ Exactly what you need to mount Chanzon's LED chips.
*by J***. on May 9, 2018*

Purchased these to go along with the Chanzon 10 pcs High Power Led Chip 4W RGBW 8 pins (300mA-350mA for Each Color 4 Watt) Multicolor Super Bright Intensity SMD COB Light Emitter Components Diode 4 W Bulb Lamp Beads...

### ⭐⭐⭐⭐⭐ Necessary for 5w Chanzons
*by K***Y on November 6, 2021*

From my early assessment, these alone won't dissipate enough heat for 5w LED but if you mount them to some aluminum, they seem to work great. Great fit for the 5w chanzon LED. Having 2 additional solder pads on + and - make wiring in series or parallel a breeze.
