busted e27 leds from ictech

[tugasi]

hi all..sino naka e27 dito? got mine a week ago.. question is bakit kaya yung blue leds lang ang sira?
I have 6 cw and 6 rb sabay naman ginawa ok lahat ng white pero busted lahat ng blue..any inputs?

[mindfreak]

ilang bulb na e27 ang hindi umiilaw? lahat ba? baka wiring ang may problem. try to plug it to other socket, swap mo sila ng iba mo na e27 and check if iilaw siya. pag ayaw pa din baka nga busted yung mismong bulb. as far i remember may 1 week warranty si ictech. baka pwede mo pa mapapalitan.

[tugasi]

lahat ng led sa isang bulb(5) 6 na piraso ayaw lahat pero yung white and blue combi ok lahat...yup try ko dalin sa saturday

driver yan dahil sa init. kung mamalasin baka nadamay na rin yung leds but you could check with a multimeter baka may isa lang na napundi kaya di sila gumagana. yan ang problema ng mga led fixtures na built in drivers, nakukulob. kaya sabi ko sayo nun bro dapat may active cooling ang mga e27 mo.

[tugasi]

upon checking..wala sila thermal paste from led to heat sink. .maybe that's one reason pinag tataka ko lang.. bakit puro blue ang punde? nakausap ko na ictech.. pinapadala sa sken sa shop..

Bka nga driver kung pundi lahat,ganyan din ang nangyari sa 3watts ko na blue din,hindi ba nailaw,dadalhin ko sa sabado,oag led lang ok pero pag yung driver sa loob,papalitan ko na lang ng bago.

[tugasi]

Bro,pakiupdate kung ano nangyari ha,bukas pako pupunta sa ictech e.ty.

remember, those are cheap * drivers.. minimum components and maybe no circuit protection at all.. walang quality control yan, basta gumana, ok na yun.. maybe a sudden spike sa meralco line, nasira na agad yung isang component.. or maybe hindi na regulate temperature, nasunog.. maraming factors.. kaya mahal din yung ibang branded leds dahil sa may protection sila, may programs sila, etc.. as they say, you get what you pay for..

[tugasi]

i dont think this is a case of you get what you pay for as all of the other leds are working fine...its hard for me to comprehend why only the blues are defective... while all whites(3rb&2cw) per bulb are all working fine,,,.. if this will be a question of cheapness then all leds should be busted at the same time

[obet_carlos]

what i meant by what i said is that your are not sure about quality.. sometimes it works, then good for you.. sometimes it doesnt.. i've had my fair share.. example, china led driver.. IME, sometimes they work for years.. sometimes they get broken in as little as 2-3 months.. or its like buying cdr-king versus other branded stuff.. there is a reason why the other is cheaper and the other is more expensive.. there is a reason why you are paying for something that is more expensive.. R&D, quality assurance, customer service, etc.. which i think ictech have little of..

to answer your question why the whites are not working, maybe the whites have a different driver from the blues.. yung driver lang ng blues yun sira.. or 1 blue led is sira.. the connection of these leds are in series.. so if 1 led goes busted and is open, all leds in the series will not light up kahit ayos pa driver.. or nagcorrode yung connections since gamit mo sa saltwater..

will have them checked later para sa iba pang mag papa gawa ng e27,, will try to install blowers to to minimize the heat
