My ratings for this:
+ Dimensions correspond to those of standard halogen bulbs (no fitting problems)
+ Very uniform light distribution (no spills, etc.)
+ Relatively low price
* Very large illumination angle (depending on the location favorable or unfavorable)
- Light color does not match halogen: There is still much too cold (RGB = 200,200,170 sebson; RGB 254,183,91 = halogen)
- Luminous flux corresponds to a maximum of 20-25W halogen (estimated - according to power precision instrument only 2.4W (3.5W stands on packing, on the lamps 3.0W)
All in all sebson is therefore not exactly brilliant and goes back to the seller.
Who actually wants to achieve the luminous flux of a 35W halogen light source and nearly his light color should be "Ledliux LED GU10-41 5.5W warm white" () access (RGB = 253,223,104 LedLiux).
