1 | Innerscene Virtual Sun A7 vs Competitor | |||||
2 | ||||||
3 | Competitor | Innerscene A7 | Natural sun/moon | |||
4 | 1 | Efficacy | 13 lm/W | 28 lm/W | ||
5 | 2 | Weight | 600 kg | 33 kg | ||
6 | Power consumption | 300 W | 8W - 200 W | |||
7 | Lumen output | 4100 lm | 5600 lm | |||
8 | 3 | Sun beam angle from nadir | 45 degrees | 30 degrees | varies | |
9 | Color Temperature (Sky) | (not listed) | 3000K-15000K | 2500K-20000K | ||
10 | Color Temperature (Sun) | (not listed) | 4500K | 3500-5000K | ||
11 | 4 | Sun beam diveragance | 30 x 10 degrees | 3 x 3 degrees | 0.5 degrees | |
12 | 5 | Focal distance to sun | ~8 m | Infinity | Infinity | |
13 | 6 | Dimmable range | not dimmable | 0.1%-100% | ||
14 | 7 | Size in ceiling | 2374x1675x687 mm | 1040x550x254 mm | ||
15 | Visible sky aperture | 960x460 mm | 920x492 mm | |||
16 | 8 | 24hr Circadium Rythmn Cycle | ||||
17 | 9 | Dynamic CCT | ||||
18 | Clearly visible sun | |||||
19 | 10 | Sun moves correctly relative to viewer | ||||
20 | 11 | Only 1 sun visible in array installation | ||||
21 | Visible sunbeams on floor/wall | |||||
22 | Visible moon and moonbeams | |||||
23 | 12 | Changes with clouds | ||||
24 | 13 | 1-10V dimming support | ||||
25 | 14 | DALI dimming support | ||||
26 | 15 | Installation | By specialized installers | Untrained electrian | ||
27 | Warranty | 2 years | 5 years | |||
28 | Ceiling plenum space requirement | 687mm / 27 inches | 254mm / 10 inches | |||
29 | Size comparison | Requires a large amount of unusable plenum space | A7 can be installed in tightly packed 2d arrays | |||

31 | Beam divergence and apparent sun distance visualized | |||||
32 | Visual apperance at different CCTs | CCT not adjustable | ||||
33 | ||||||
34 | 1 | Lower Efficacy translates to less light per watt and more heat generated that must be cooled through air conditioning | ||||
35 | 2 | Competitor requires 18X more structual weight support compared to Innerscene VS7 making competitor much more expensive to install | ||||
36 | 3 | A beam angle of 45 degrees makes the sun appear to be low in the sky. 30 degrees allows occupants to comfortably walk around without eye glare | ||||
37 | 4 | Divergance angle determines sunbeam sharpness on the floor, size of the sun in the sky as ceiling height increases, and apparent distance to the sun | ||||
38 | 5 | Optically the sun for competitor appears to be at a distance of about 8m while IVS7 has an optical focal distance at infinity making it look far away | ||||
39 | 6 | A7 is capable of moonlight, bright sunlight, and any brightness variation in-between. Competitor's sun and sky cannot be dimmed | ||||
40 | 7 | Competitor requires 18X more ceiling volume compared to A7. Competitor requires nearly 3X as much ceiling depth compared is A7 | ||||
41 | 8 | Using a built-in clock, A7 automatically calculates sunrise & sunset times based on your GPS location and uses this to adjust light color for the time of day | ||||
42 | 9 | Variable CCT allows for warm color temperatures in the morning and evening and gives flexability for harmonizing with other lighting in the room | ||||
43 | 10 | When walking under competitor, the sun does not move at the correct speed in the sky because of incorrect focal distance and beam divergance angle | ||||
44 | 11 | When a 1D or 2D array of A7 units are installed in the ceiling, users only see 1 sun at a time no matter how many units or users are present | ||||
45 | 12 | A7 is able to modulate sun and sky seperately as well as control CCT which allows it to simulate the effect of clouds passing overhead | ||||
46 | 13 | 1-10V dimming is the most popular dimming system in the world | ||||
47 | 14 | Using DALI or 1-10V dimming connected to proximity sensors, IVS7 can be configured to dim or turn off when no one is present to reduce power consumption | ||||
48 | 15 | Competing product is shipped in multiple parts and assembled onsite by specialized installers. A7 is installed by a regular electrician and fits through any doorway |
