The main difference between the two products is that the LFC Kit is meant to use as an accessory with a projector of your choosing, whereas, the LF2/2+ is an all-in-one solution, projector included. Which device to use depends on the size of the projection you are looking to do.
The size of the projection with the LFC Kit will be dependent on the projector you use with it and the size of the projection with the LF2/2+ will be up to ~6ft wide with bright ambient lighting and up to ~12 ft wide in darker ambient lighting.
If you have projectors of your own (or want to use a more powerful/high lumen projector) and wish to do a medium-large scale installation, we would recommend the LFC Kit. If you are looking for an all-in-one solution for smaller-scale installations, we recommend the LF2/2+ AR projector. You can see projects made by our team here: lght.fm/projects and you can filter these by each product to see examples of each.
The LFC Kit is an accessory composed of a computer and camera to use with your own projector to make projected AR experiences (projector not included). You can use LFC with most normal or short-throw projectors for almost any size scene. The size of your scene will depend on the projector you use. The LFC supports projectors that meet the following criteria:
- HDMI input
- Throw Ratio: 0.5 – 2.0
- Any brightness (depending on ambient light)
- Any lamp type (e.g., LED, Laser, bulb)
For the LFC, make sure the projector you plan to use is within the supported specs and throw ratio. We recommend using projector central's search feature to do this. For instance, you can view projectors by supported throw ratio by doing a search like this one (min/max throw ratio = 0.5-2.0). If you don't already have a projector, using this search feature will help you narrow in on one that is supported and fits your use case. You can read more about this here: Projector Compatibility
LF2/2+ is an all-in-one solution to make projected AR experiences -- it is a projector with a camera built into it. The LF2 projector's throw ratio is 1.2, and the brightness is 1,000 lumens. We recommend this solution for small-scale installations and indoor spaces like home offices and retail displays. We recommend LF2/2+ for scenes up to 6ft with bright ambient lighting and up to 12ft in darker ambient lighting. To learn more about the range of the LF2, see here How large of an area does the LF2/2+cover?
Please note -- Currently, LF2/2+ does work as a typical projector via an HDMI connection, however, the main functionality of the LF2/2+ is projection mapping.
With the latest firmware release, there is a new projector menu, now with basic keystone correction, projection modes, and more. You can also control the projection mode within Lightform Creator, there is a button to change the projector mode (front, rear, etc.) to invert the image accordingly.
