I ordered a pair of these bulbs for my K&M piano stand light, having read good reports of them and fed up with the short lifespan of the old-fashioned filament lights. Initial impressions were excellent: great light quality and output making the music easy to read even in an extremely dark theatre pit. However, they are not cheap and, having only used the lamp a couple of times, one of the bulbs has already died. I will be approaching Thomann for a replacement, but as a distance (UK) buyer it may not be cost-effective to do this. Disappointed.
Purchased these to replace tungsten filament type bulb. Not as bright as I had hoped, and the light is very white compared to a tungsten bulb. On the plus side, the lamp assembly now runs cool to the touch and the bulb doesn't fail if the music stand the lamp is attached to falls over (or is knocked).
Plus points Cool running Low power consumption Harder to break
Minus points Light output lower than tungsten equivalent Light is very white
But the band member who uses the lamp assembly on his music stand is happy with it...
