Philips 6605 - 10w 6v G4 M42 Single Ended Halogen Light Bulb

Instrument Bulbs

The bulbs arrived promptly, were the correct specification and were only were far cheaper than the ones from the science equipment supplier I normally purchase from.

Spectrometer bulb

This bulb seems to work just fine in our Genesys spectrometers as a replacement bulb, much cheaper as well!

Perfect

Easy to find exactly what I needed and at a fraction of the price
