Light setup

Light types

GE	Blender
Point	Point
Spot	Spot
Directional	Sun

Note: Area light type in Blender is not supported in GE

Light attributes:

Giants Editor | Blender (Eevee)

Spot light only:

Cone Angle = Spot Shape → Size

Drop Off = Spot Shape → Blend (1 = 5 | 0.750 = 3.75 | 0.5 = 2.5 | 0.250 = 1.25 | 0.000 = 0)

All light types:

Range = Custom Distance → Distance (40 in Blender = 40 in GE)

Cast Shadow Map = Shadow need to be checked (Lights tab)

Color:

Standard Light Settings

Real light	Color (R, G, B)	Power	Specular	Radius	Custom Distance	Size	Blend
Backlights	0.5, 0, 0	2.5 W	1.00	0.25 m	2.5 m	130°	0
Turnlights	0.31, 0.14, 0	4 W	1.00	0.25 m	4 m	120°	0
Position lights	1, 1, 1	2.5 W	1.00	0.25 m	2.5 m	130°	0
Static Lights

Orange	0.569, 0.286, 0.161
White	0.3, 0.3, 0.3

Export to I3D

To be able to export Real Lights from Blender to i3d, make sure the "Lights" checkbox is checked in "Export Options", if this isn't checked your Real Lights will be exported as transform groups.
