Thermal Adhesive Grease and LED driver

[big_ben102000]

hey people,

I am currently looking for Thermal adhesive grease and LED drivers with 48v, 700ma output or similar. does anyone know where to get them?

I previously got a tube of Thermal grease from sim lim tower but its not the adhesive kind. For the LED driver, i tried looking at sim lim tower, they only have 12v output, i came across a 48v ouput one but it doesnt look very appealing (doesnt have a brand and doesnt looking professional done)

If anyone is interested in trading thermal adhesive grease with my thermal grease (~70g) please do pm me.

thanks everyone.

Bro, i ordered online, how many led bulb you need themal grease? i can pass you some if not a lot needed.

[big_ben102000]

i got 39 leds to "stick" on my heat sink haha.. quite afew. yea i saw some too online. was wondering if i can get it locally. shipping takes awhile. Thanks for the generosity

i see, beside the half tub i have, i recall i got another tub but not if is adhesive kind, and i will go back and check.

for the led driver, why need 48v output？ thought most of 3w led clips are 12 v one?

I am not very good with electonics, i am using a layout i saw from somwhere else, connecting LED in series, based on my design, i would need an output of 48V there abouts that is dimmable. I have found a model online just looking to see if i can get them locally.

Bro,

The number of LEDs in series determine the voltage. So if you have 3 LEDs you need 12 v, 6 LEDs 24v and so on

[big_ben102000]

yea i was planning to have 1 LED drivers with 48v (dimmable ) and 2 other driver (36v each) non dimmable to power up the 39 LEDS =)

Then the best option is to use Meanwell. You can get them from online

[big_ben102000]

yea i saw meanwell. was hoping to get it locally, as shipping cost quite abit. unfortunately, couldnt seem to find them anywhere including sim lim tower.

Can try tabao instead of rapidled. Meanwell is taiwan brand, get from China shall be ok.

Im using 4x meanwell lpc-35-700 for my 48x royal blue led. Non dimmable.

Sg.element14.com selling each 67.39$

Rapidled only 15usd each. Shipping only 38usd for 4 piece . Not sure if taobao have .

Alternatively , u can share cost witj reefer. Split the shipping cost , even cheaper.

Aquastyle LED is selling them for USD15 as well. Was looking at getting the Maxwellen LED Dimmable Driver (12-20)x3w from them which is USD22. Shipping is USD16. I understand that Meanwell has a good reputation and alot of reefers are using them. Anyone has any experience with Maxwellen drivers?

Bro sherman, youdontknowme, do you guys have any experience in connecting leds in parallels ?

[megacue]

Dont run parallel. U be dividing the amp (current) into number of parallel string. Driver output 1a if run 2 parallel string will only give u max 500ma. Parallel is only good for violet or low current demand led. Most violet is 700ma if u intend to max the intensity. That is my view, kindly counter check online like nano reef forum

Alright thanks for the input megacue, all of my LEDs are running at 700ma, so i guess thats is not an option.
