LED voltage and Removing adhesive?

Another way to test the voltage and adjust is too run your voltmeter inline between the driver and the lead's. So basically attach 1 probe to the red wire coming from the driver and the other probe to the red wire connected to your leds. Make sure your driver is turned down all the way, and all your led's are wired together before powering up.

Edit, maybe i got lucky but when I swapped out some rb's for blues, i just used a sharp screwdriver and my leds popped right off, well with a little force

 

Let me know how getting that star off goes.

If the epoxy is applied properly and there is no air gap between the star and heat sink you should not be able to just pop them off.

Here's that LED article I said I was working on.

now nothings permenant! I'm pretty sure i mixed the epoxy right, put the right amount on(small amount), lightly pushed and twisted and held the star, and yet, with a sharp slightly bent screw driver, mine come off. Now they are for sure as permanent as they need to be, but i've read a lot of people that have been able to pop them off

 

If it makes you feel better..."mmmk"

But if you didn't have a thin layer on the entire star the thermal conductivity is lowered, lessening the life of the LED.
If you're just popping them off without damaging the star or scaring the heatsink then you are not applying the silver like it was meant to be applied.

I can barely "pop" LED's off when I use the thermal pads. Even with a sharp edge of a knife.

But I'm not going to debate this with you.

 

ok!

 

luckly I did not evenly cover that one it poped right off

 

Nah they'll come off(sorry reef monkey), but found a email from rapidled, and they agree that they'll pop off too, just some can be be hard, but they will pop off.

 

Just replaced another rb with a blue, and it came off with a little muscle, but not too much. Thermal adhesive is def the way to go.

 

so yeah it comes off the heatsink but the led is forever bonded to glue and there for trash so i say ur both rite .just saying

 

nah ya can get it off the star too! Just takes some time and patience.
