March 1st, 2013 04:15 PM #11the best way is to add a resistor in series to each bulb.. nalimutan ko na yung resistor value pero yun ang tama...

thank you sa mga sagot sirs.
so. it's better to have the bulbs connected in PARALLEL. mapundi man 'yung isa, sindi pa rin
'yung isa, kasi nga the same voltage (12V) will still pass thru.
experience ko kasi dun sa Lolo 2002 XUV namin. 'yung ibang LED Lamps sa 3rd
Brake Lamps (spoiler ba tawag doon?) eh pundi na. dinala namin sa Isuzu Casa.
Sabi nung SA, di raw sila nagre- repair ng ganun. papalitan daw 'yung buong "spoiler".
about 20K petot daw 'yun. wala rin silang stock.
so, returning to house, binaklas ko spoiler, inalis ko two bulbs na pundi. went to raon.
marami sa raon, same look, pero iba- iba ratings (voltage and ampere raw). eh hindi ko rin alam.
SA asked "saan mo ba gagamitin sir? "sa isuzu van" sabi ko. ang bilis ni Tita. "PARALLEL connection lang 'yan,
12volts 'yan, 15petot isa sir, ilan ang kukunin niyo?" buy ako 20pcs = 300petot... so, tralala... so and so...
went home... kabit the other day by an appliance tech (P200 + 1 kaha Philip),
good as new... hahaha! imagine, muntik pa ako madale ng P20K sa Casa ah.

Alam nyo naman ang casa, konting gasgas, palit na buong kaha.. pundi isang ilaw palit buong assembly.. hehehe.
270 ohms ginamit ko sa 2 pcs LED strips connected parallel.. medyo malabo buga nya compared sa w/o resistor pero at least mas tatagal yung buhay ng LED proteksyon sa sudden voltage surges.

Bro.,- "Some animals are more equal than the others"....
Same is true with electronic components, walang exactly pareho... Araw-araw na-e-encounter namin iyan dito sa opis....
In your case, it may take a while for an LED to burn-out, even if it has more than 12V across.... I suggest you experiment first....

thanks sa suggestion sir yapoy.. mukhang yan nga po dapat kong gawin..
anybody here knows anong ohm ng resistor dapat ikabit and how? hehe
sir cvt kung ganun mukhang resistor nalang nga magagawa ko.. hehe... thanks
thanks guys

March 1st, 2013 08:55 PM #17^check the spec of the LED strip. pwede mo gamitin ang Power (Watt) or Current (Ampere) or Resistance (Ohm) rating. or use Ohmmeter.
meron kang 24V source. dapat ang Resistor ay equal or close to the value ng Resistance ng LED strip. example, if 300 ohms ang LED strip, you need a 300 ohms resistor to connect in series.
Voltage Divider lang yan kaya saktong 12V ang makukuha ng LED strip.

Probably looks like a Coke sakto. Yes, where did you buy it?
