Halogen lamps were provided with 390 lumens. According to previous reviews and the performance data I have chosen and ordered this Mailux. With 4 watts for the light yield also very economical.
The light output is very good, the lamp is really equal in brightness. The light color is minimal cooler, but what I do not just pretty. The lamp is huge compared to the G9 halogen lamps - that's why I had initially ordered only one lamp - but fits easily in my lights. The wires from the G9 version are also very good - just a few cheap Halos had as often clamped or wobbled; None at the significantly heavier Mailux.
Conclusion: Very good light performance and light color, note dimensions!
