LED Lightbulbs - super efficient light bulbs

  • My CDR buking LED project.

  • cool

  • nice!

    pati cd canister cdrking?
  • Not sure if the cd canister is cdrking. Because i have a lot of those.
    Here is the circuit if you want to make one.


    12V socket is at the back for charging.

  • two 3W CDRKing bulbs na pang security lights ko ay gumagana pa amazingly. almost two years na siguro or lagpas pa. around 100+ lang bili ko dati
  • any recommended LED bulbs these days? Pang kwarto lang mga 15sqm
  • Any recommended na LED Light na pag maliwanag na kusa namamatay as in 0W then matic din umiilaw pag madilim na? Plano ko lagay sa may gate ko dalas kasi makalimutan turn off sa umaga. Yung iba ko kasi nakikita yung sa omni 10W. Gusto ko sana parang gaya lang ng gamit ko now 3W lang kasi 2 posted naman may ilaw. Thanks.

    impossible yun, kailangan ng power, a few tenths of a watt siguro to power the photosensor. If you use a de pihit or spring powered macgyver timer, yun no electricity used.





    100 pesos from cdrking. I had two, madali masira. And masyado insensitive ang sensor. Bright na in the morning bago mamatay ang ilaw. Buy branded nalang

    Thanks boss. Right now ano na gamit nyo? Oo nga sorry impossible nga na 0W pala. Hehe
  • OMNI gamit ko sa photo sensors - lampas isang taon buhay.
    mag wire ka manually from power to load to sensor Php250 sa mga mall hardware stores.
    may stock na ng aako sa bahay dahil apat naka deploy sa paligid at sa upper floors.

    Omni nga din napm ko meron daw sila. Kaso di ako marunong sa ganyan baka makuryente ako. Haha.

    sa amin manual, human ang nag on and off

    sa relatives ko cdrking digital appliance timer which surprisingly is still alive. Ang analog timer mabilis masira
  • Tag ulan nanaman.

    Nag fli flicker/nightlite ang ibang ilaw ko including CFL pag naka off kasi basa and grounded ang power lines

    Also, may butas ang roof. A few bulbs were destroyed by water. Will need to fix the roof later.

    I fond one still working bulb with the plastic dome half filled with water. But still works. I carefully drilled a hole on the apex of the dome and drained the water then put it back. Now water still enters the bulb but it exits via the hole so it still works.
  • update: the wet led bulb which I drilled still works after a night of rain.

    Did more work. Sealed the small holes on the butt side (pointing up) of the bulb (you see that in some older firefly and akari bulbs) with candle wax and oiled the socket and the screw base with wd 40 to at least delay rusting.

    wax is a small fire hazard but it will melt and drip away if it ever is too hot.

  • typical LED filament bulb on the left, incandescent on the right. Saw one very similar today in the hardware section of a major supermarket




    You can see that instead of the tripartite body plan of a normal LED bulb (screw:body:dome), it mimics the bipartite body plan of an incandescent (screw:dome). But for my purposes the point is (if you have been reading my last points) that it seems to be watertight since there is only one joint and the metal is overhanging the joint plus its probably sealed with glue.

    I would have bought it except for the fact that its e14
  • Update: the akari 5w is juuuust hot enough to melt candle wax at least partially. And this is with cool weather.

    But the drain hole keeps it alive.

    A 4w firefly that had some water damage (slightly dimmer) seems to have recovered. I placed candle wax and drilled a hole too and replaced it in the same spot. Heat must have dried out the electronics or something. Now it looks like almost full light output

  • planning to install LED strips around the rooms of the house for accent lighting:

    1. will be using a computer PSU kasi may spare ako, waste not want not...
    2. saan makakabili ng plastic diffuser katulad nito?


    3. any tips, i-DIY ko lang kasi
  • 1. will be using a computer PSU kasi may spare ako, waste not want not...

    I predict that the psu being very oversized for the LED strips would consume more watts than a dedicated LED driver. The absence of the fan alone in dedicated LED drivers drops consumption a bit

    but hey it would still work, you gotta compute if the extra wattage is worth the lesser cost
  • Bought a firefly 5w 480 lumen photosensor bulb. Php 264 (with the ongoing 20% off sale from firefly)

    I give it 4/5 stars. Minus 1 star because

    * its freaking hard to find. I saw 4 boxes and when I went back in 1 week, sold out na. Naghanap ako all over the place and finally found another one. Minus 0.5 stars
    * only available in warm white. Minus 0.2 stars
    * I've only seen 5w and 10w. Minus 0.2 stars
    * the photosensor is much much better than cdrking's version. But it could still use a few percentage points boost in sensitivity para talagang dark bago mag on. Minus 0.1 stars

  • Saan po sa Divisoria or Raon nakakabili ng LED strip lights? Pwede po ba magbanggit ng names ng shop dito?
    Salamat.

    Salamat.

    Soler St. sa Binondo yung maraming LED light shops.... hanapin niyo yung pwedeng ligyan ng LED Driver instead of custom made ones na dinadala nila... kasi yung 12v Driver ginagamit din ng stereo/radio ng kotse sa electronics stores sa raon

    simula ka sa kahit sa Isetan Recto at pumasok ka sa side ng delivery area then pagnakita mo yung isang malaking lighting shops yung isang kanto pakanan yun na ang Soler st. diretsuhin mo hanggang sa corner masangkay st. dun ang area ng lighting shops
  • @Vashtard
    Maraming salamat!
    Ano yung custom made, parang ipa-plug na lang sa wall outlet?
  • Ano yung custom made, parang ipa-plug na lang sa wall outlet?

    tama... baka mahirap yung specs kung mac-gyverize mo pa power supply

    better na yung LED strip na para pipili ka ng wattage ng power supply... kasi yung iba na meron na power supply hinde mong pwede idikit para extend while the LED strip na walang power supply pwede mo pang idikit pero lakasan mo yung wattage ng power supply

    also follow the voltage requirement ng LED strips... in my experience on that lalo na sa LED chandelier meron din sila na 12v Driver at lalo na 24v drivers
  • @Vashtard
    I see. Plano ko yung SMD 5050 RGB strip na per meter ang kunin kung available tsaka LED driver at connectors. Tanong ulit sir, ano ba tawag sa RGB strip na kaya mag produce ng iba-ibang kulay aside from solid red, green or blue? Hindi ko kailangan ng strip na kayang mag produce ng iba-ibang patterns. Ano po ba tawag dun? Salamat ulit.

  • Sa tingin ko yung RGB striplight na tig isa na Red Green Blue on a LED diode...

    To make that RGB striplight work you have to install a RGB controller on the RGB striplight then LED driver

    Di ko na abot yung RGB striplight... pero kabisado ko yung single colored ones at yan yung the most simplest to install
  • Mga sir, ask ko lang kung ano okay na ilaw pang kwarto? Nasira ko kasi yung socket ng bukilya ba tawag dun. Halos lahat ng ilaw namin ay GES na 7w yung may 5yrs warranty.

    Okay ba yung nxled na dimmable light? Yung bilog.

    TIA
