Malaki ang draw ng current nito basi sa schema ....
current x N , N= No. of parallel branch....
I will not recommend for u....

tsaka medyo mura lang yata kung bibili na lang ng yari na. pero kung sa mga nais mag project okay na din.

ganun po ba, sir mga ilang oras kaya aabutin ng battery? kagagawa ko lang kc to kanina di ko pa na test ng maigi... thanks.. po |

sir bale sakin po is mga junk lang yung iba, binilhan ko lang ng dalawang piyesa para magamit, at saka gusto ko ring matutunan kung paano siya mag work, dagdag kaalaman para sa akin...  |

depende sa AMPhr ng bateria mo... kung ang battery mo ay 4.5AMPhr Ang min.current consumption mo is roughly 30mA.... ROUGH lng ito... It=30mA x 12 = 360 mA or .36A di pa kasali lhat ng current consumptions ng iba.... .36A x Batt Life = 4.5A-Hr Batt life = Approx. 12 Hrs.. Continuous |

ALL I CAN SAY: ok na rin yan as a solid state emergency lamp.. iba nga jan is using 6v or 12V DC bulb (w/c is slower to light) and is more power hungry than LEDs...  depende na yan how you set the R1-R12 values... |

thank you sir, kahit mga 5 hours ok lang, kc pang ilaw lang sa bahay kung walang kuryente lalo na pag may bagyo, hindi ko naman po gagamitin ng 24 hours e.. |

balak ko i-convert sa led yung mga emergency lights namin na gumagamit ng mini-fluorescent bulbs kasi malakas sa baterya ... kaya bumili muna ako ng murang led e-light sa sm para magkaroon ng idea sa circuit ... P495 lang, 44 led's na  ito yung control board  wala syang transformer, it uses a 2.2uF/250VAC capacitor with 220k resistor in parallel to drop the voltage ... i believe the single big blue resistor is used as the current limiter (didn't get the value argh!) for the whole led array, which could explain why the current from the battery is 200mA during 44-led operation and 150mA (not 100!) during 22-led operation paalala lang ... huwag kalikutin ito na nakasaksak sa AC .... LIVE ang circuit eh! palagay ko pwede makagawa ng mas simpleng circuit kapag gumamit ng relay kesa transistor switching ... pero kung gagayahin itong 44-led, baka mas magastos sa presyo ng led pa lang ... magkano nga ba presyo ng ganitong led sa raon?  |

pwede bang ibabad na naka-charge iyan? me trickle charge function ba? at saang tindahan mo sa sm nabili yan, sa ace hardware ba? thanks!
bibili ako niya kung pwedeng ibabad na naka-charge lang.

hindi ko sinukat charging current kasi nga live yung circuit ... pero makikita sa control board na mababa lang charging current dahil capacitor ang input designed talaga sya as emergency light na nakababad sa AC ... kapag blackout, sisindi yung mga led's at mamamatay uli pagbalik ng kuryente at sisindi yung red "charging" led nabili ko sa sm rosales (pangasinan), Ace Express ang tawag nila sa hardware section sa sm dept store (2nd flr) |

konti lang ang led ng mga yun. eto marami, pag nasira, meron ka pa ring makakahoy na led. yung led kasi bawat isa ay 20pesos. pwede siguro ma-modify ang circuit niyan to accept 12v7ah battery para mas matagal ang liwanag |
