recycled cfl ang gamit namin mostly dito sa street light namin,inumpisahan irecyle nung wala pang china made cfl. ok naman ang dating ng liwanag!

try nyo to at super liwanag talaga,cfl 18 watts at fl type (pahaba) na10 watts lang
kaya lang 3 months lang ang itatagal ng fl tube kung overnite na nakasindi!

Additional info lang.

If gusto nyo mag modify ng electronic ballast ng 10~15W CFL para mag drive ng 20W tube lamp palitan nyo yung transistor driver from MJE13001 to MJE13003 or pede din any transistor na mas mataas pa dito basta yung VCE 700V and IC is 1.5A nung driver transistor, Nag recycle lang nga ako nung transistor (2x 2SC4106 overkill na eto IC ~ 3A) galing sa lumang PC SMPS.

And of course I-increase nyo yung brightness kasi from 10~15W cya galing by modifying yung main inductor from 10 to 15 ohms, ewan ilang turns and inductance, wala kasi akong inductance meter, resistance lang basihan ko then 47nF yung capacitor.

Gumana naman. Current measured @ 5mA on my Analog MM.

Sana makatulong ito, curious lang kasi ako sa CFL circuits and wala na akong makuha 20W electronic ballast kayun ayun modify ko na lang Smiley

Good info sir.

Talking about this, natry ko na rin kanina. Using phalips 18W to a 20W FL. Ayun gumagana nga. Naobserve ko kulang sa liwanag, sa susunod naman hanap ako ng 20, 22, or 23 watts.

Kagandahan, no flicker sya kaya bawas sa on-off cycle ng FL tube.

actually meron, at mas nadagdagan pa Smiley kaya hindi napapansin ng ating mata

same lang ang circuit nitong CFL ballast compared don sa conventional, ang pinagkaiba lang nito ay nirerectify nya muna yung AC source (60hz dito saatin) to DC, bago ioscillate ng mas mabilis hanggang 18-22khz, na rason kung bakit ferrite ang core ng CFL ballast, mas maliit din ang core, at mas mabilis din ang on and off, kaya hindi gaano pansin ng mata ng tao

^No I mean sir is during switching on. Pag switch ilaw na talaga, di kagaya ng conventional na flickering pa sya karaniwan.

And talking about this, any difference kaya sa tagal ng serbisyo between conventional ballast sa pinalitan na galing sa CFL circuit? With same spec FL tube.

trice ang life span ng tube with higher frequency ballast
