+ Lighter than 7W LEDs my NoName initial purchase
+ Almost as bright as a 40 watt-Halo, therefore actually corresponds to the description that this 4W produce about 35W light Halo
+ "Spot" is an understatement, especially when exposed a white wall or ceiling lighting margins are generous and soft
+ The light is fantastic, almost like the good old light bulb, definitely the color of the halo
+ Excellent match in the GU10 slots because wackelts no longer than the brand Halos
- Comes to mind nothing :-)
If Philips now just tinkering these lamps for G9 and R7S in size, as they are also available as halos, then I am the first of the purchases, I promise!
