LED Lightbulbs - super efficient light bulbs

  • 25w incandescent? Mga 3w led
    If cfl, mga 1/2 or 1/3, depende sa lumen
  • @lezalga

    May ibang LED na dimmable talaga, ang sabi nila madali daw masira ang LED na non-dimmable kapag nilagay ito sa may dimmer switch. In my case, wala pa naman nasisira.

    Now, if in case youre using a dimmable LED bulb, the answer is yes, bababa konsumo pag dini-dim mo ito. Parang sa halogen at incandescent din.


    25W incandescent? Eh baka kahit 4W na LED bulb mas malakas pa dyan. Hehe


    Yes sir, lahat ng GES ko 5yrs warranty. Sa aking pananaw, 3yrs ang minimum warranty dapat sa napaka mamahal na bumbilyang ito.
  • typical incandescent bulb is 16 lumens per watt, compared to the 60 lm/W of a compact fluorescent bulb.

    16x25 = 400

    GES 4w = 90 lumen/watt = 360 lumens
    firefly 3w = 230 lm = 76.6 lm/w, so a firefly 5w = 380 lm

    you MIGHT, repeat might be able to get away with a GES 3w or firefly 3w since the light is directional pointing down unlike in an incandescent where some is wasted going up. but I would not risk it

    the good thing about having many LEd light bulbs in the house is if I want to convert a room into LEd I just get one of the bulbs I already own and try it out in the room to get a ballpark estimate of what wattage I want to buy

  • Just finished replacing the 2x18w fluorescent tubes over the weekend with GES 8W 2yrs warranty. Though rated 720lm lang yung isang LED Tube, mas-maliwanag pa naging outcome nung 2 LED Tubes compared to the original 2x18W ballast driven fluorescent tubes. Sulit na sulit na yung 359 pesos each na LED tubes :)
  • Ang mahal ng dimmable led 3w palang 375php na tapos dimmer switxh 285php. Saka na. Bumili nlng muna ko 5.5w ang liwanag para sa computer area ko. Nolipat ko na kasi sa sala yung cdrking 3w ko
  • Jam

    Oo nga raw madali masira. Pero ikaw gamit mo sa dimmer switch e non dimmable led? Gsno na katagal?
  • Conversion.

  • wala ata 100 lumen/watt (kasama efficiency ng power supply sa pwet ng bulb I assume) sa pinas. pinakamataas 90 (GES)

  • Both the GE and Philips 7 W have 600 lumens output, a 60W incandescent replacement. They cost the same also after the 20% discount on Philips.

    Akari is on sale. I got a buy one take one 1W.
  • cfl pala yung samin,hehe
    anyway thanks po sa lahat ng sumagot, appreciate it.
    LED Bulb shopping ako sa weekend :)

    Teka sir, mali ako, hindi ko pa pala napapalitan ng LED yung mga CFL(x10 living room center light) kong naka dimmer switch, hindi naman kasi ito masyado ginagamit, at pang occasion lang.

    Wala pang nasisira sa CFL, hihintayin ko na lang 'to mapundi isa-isa bago ko palitan ng dimmable LEDs. At kung gaano na katagal yung sampung CFL na yun, more than 5-6yrs.


    Just for reference, sa specs ng GES LED bulb sa box nito, ganito nakalagay;

    Incandescent - - - - - - - CFL - - - - - - - LED(daylight 5800K-6300K)
    220Lm - - - - - - - - - - 240Lm - - - - - 290Lm +/-10%
    22watts - - - - - - - - - 6watts - - - - - - 3watts
  • guys for practicality reasons

    pag yung led bulb nyo ay may konting ilaw pa kahit nakapatay (usu dahil sa switch na may off light indicator), papalitan nyo pa ba yung switch nyo sa bahay? o hahayaan nyo na alng na may konting ilaw pa rin pag nakapatay?

    nakakabawas ba talaga sa 20000 or 40ooo lifespan yun?
  • In my case hindi ko pinalitan yung mga switch ko, ok lang sakin na medyo naka dim yung mga LED pag naka off.

    Also napansin ko sa mga new series ng GES bulbs, hindi na sila naka dim or wala na yung konting ilaw pag naka off kahit pa yung switch ko may light indicator.

    Sa GES bulb lang yung ganito, yung mga Akari at Landlite ko, ganon pa din, may konting ilaw pa din kahit naka off ang switch.

    Sa GES makikita mo series nasa bulb mismo, 4 digit number.

    Example: yung first batch ng GES ko is 1107 series. Compared to my recently acquired ones which has 1206 and 1213

    As to lifespan, siguro may bawas pero kontin konti lang na almost negligible yung ikakabawas niya.
  • i never encounted this in both the GES and firefly LED bulbs that i bought re: yung naiiwang ilaw
  • i never saw this with all my LEDs (1 akari, 2 stark, 1 firefly, 1 phillips, rest GES)
  • @951

    May I know your GES bulbs series mga sir?

    If you have the same series(1107) as my first batch GES and does not have this issue(very dim light), malamang eh nasa wirings ang culprit nung sakin at yung ibang nakaka experience nito.

    Pero ang napansin ko lang talaga yung mga bagong labas at mataas na series(12** above) ng GES bulbs, wala naman yung particular issue na yun.

    Wala na kong paki sa ibang brands na meron ako since konti lang naman sila, unlike my GES inventory.
  • the first GES i bought dec 2012 is up high and i can't get at it at the moment (nasa office and sarado for the holidays). the box says model WECL-9w if that helps

  • next oldest is probably a 5.5w 5 year warranty dated 6/2013. nakalagay is #1209

  • @jam

    it says 1310. tested this sa provincial house namin at dito sa manila. same results. pag off, totally off, no residual light. just like my Firefly LED
  • Mas bago nga mga GES bulbs niyo mga sir since mas higher ang series numbers niyo.

    1107 sakin bought around 2011 pa. And just the same, yung ibang GES ko na 12** above na series, walang issue.

    Too bad hindi pwede ipawarranty yung ganitong issue. I just have to live with it. Hehe

    Anyway, tnx mga ser.
  • nagkaganyan din yung 5.5w GES (2yr warranty) sa cr namin pero for few hours lang :)
