定格の半分程度の電流300mA程でも、放熱板とかで放熱しないと熱暴走をおこしてして壊れます。定格600mAともなると理論上4倍以上の相当な放熱器の対策が必要です。

With only the chanzo heat sink, these guys got pretty hot. I mounted that heat sink to a piece of aluminum, with some thermal compound, and the temp dropped dramatically. They are just warm to touch if you dissipate all that heat they produce. Ran them for 20ish minutes with no noticeable change to the temperature.A lot of reviews complain about the lifespan of these LED. I'm thinking they aren't dealing with that heat effectively.Side note.... don't mess around with these guys without some eye protection. They are bright!I'll update if there are issues after some run time.

These LEDs are very bright. Wished the positive and negative poles were marked better. When presoldering the leads the markings are covered by solder. I used a marker to color the positive end of the light so if I dropped it I wouldn't need to test the polarity before soldering in place.

No way these are 5W. Current measurement shows around 1W of power.They get extremely hot, and burn out easily, despite being connected to spec voltage.Advantages are that price is not bad for US stock, colors are nice, they are small and light. Perhaps run at slightly below recommended voltage, which also means a lot less brightness.

Real sensitive on the volts , but if done correctly awesome LEDs . Would recommend highly, I'll be a returning customer, hopefully buy bulk

Great LEDs, I needed only 3 for my project, repairing a swimming pool light. was easy using the backplate and an LED driver PS 18- 34Vdc. which really would be the best bet @ 600 ma output. So far it is working great, Thank you.

I bought this leds to fix my burnt aftermarket angel eye bulbs on a BMW. They we're the exact replacement I was looking for. They are bright, but not as bright as the original ones. Measured out 3500 lumens a pair of leds vs 8000 lumens the original ones had. Color was great match though (cool white), not too blueish, simply pure cool white.

Very bright but heavy on battery current for an LED. These devices are bought because they are economical but not the Chanson ones. Also note. When these devices are sold it should be made clear if 5W is an equivalent value or an actual current drawn.

These are great little chips for the price. Driven at just over 6V, they put out around 600 microeinsteins of photosynthetically-active radiation (measured a few centimeters from the chip using a Li-Cor quantum sensor) but I had one meltdown while testing it (although admittedly I wasn't using a heat-sink). I'm running these closer to 5.5V to avoid thermal runaway and they are giving off nearer to 100 microeinsteins at this voltage with almost no heating of the chip.
