I just bought a set of 4 and I order a 2é time a batch of 10 ditto lighting 20W and above all much less hot temperature! Electric conso divided by 6 color "Warm White" 2900 K is very close to the halogen: no visible difference next to a halogen. the front is glass: it does not directly affect the LEDs unlike some competing models said "economic" remains to be seen longevity? Note: CE and Made in China label, although SEBSON = German brand I recommend buying
