  • sir marami salamat sa info. ipapakalas ko n lang muna ung sirang led driver sa electrician, hirap kc tangalin ung chandelier mabigat.

    pinakamabigat na LED Chandelier na benta namin before is 30kg (hinde pa yan custom ha... kapag customized nasa 50-62kg kasi merged yung 2 same fixtures)

    kung yung 1st pic I mentioned apparently pwede rin naman ikabit ng L at N para umilaw.... pero you should make a ground wiring para safer... those boxes has a ground output, pero by my experience kahit bakal yang katawan pwede ka mapa electric shock niyan... then again ginagamit din namin sa LED Strip Lights (apparently most LED chandeliers use LED striplights of SMD5050 and SMD3528 ones

    okay.. eto yung types ng LED driver based from my experience on LED chandeliers
    - Naked types: Basically hubad pero covered with shrink wrap wire covers, yun ang hardest kasi walang specs posted worst nito kahit sa manual ng LED chandeliers wala rin sinabi ilang voltage and wattage

    - Encased ones: usually meron yan at common sa LED fixtures and LED Panel lights kung parang Bakal na block yung driver nila which is supposed Waterproof to a certain degree, yung pinost ko dati sa 2nd which is low end ones

    - Heavy duty types: usually nasa 12v and 24v versions, comes with different wattages to suit your LED applications... usually striplight ang gumagamit niyan pero meron naman sa Chandelier

    Follow the polarity ng connector of the AC adaptor/laptop charger to the LED TV




    Just make sure compatible or tama polarity...
