Good Philips product, from the luminosity slightly weaker than the LEDON LED bulbs capsule G9 with 3.5W, although according to factory specifications Both achieve the 200 lumens. The advantage is the slightly smaller Dimension of Philips (approximately 5mm shorter than LEDON 3.5 W and about 2mm less in diameter). In addition, the price of EUR 6.50 is only about 2/3 of the price of LEDON illuminant. No buzzing or humming. In direct comparison with the LEDON 3.5 Watt LED G9 spare it seems a bit too light "green". Subject depth felt it is not quite as hot. The Philips product comes with me in Game cabinet twice used here is the "flask" in the the lamps plugged, slightly narrower than in my hallway lamps where 5x the LEDON is in use. Here me the smaller dimension was important, I possibly due to the expected heat build (if too little "Air" is on to large bulbs can not demise early) this want.
