Manufacturer Description
“Extend your PC’s RGB lighting with the CORSAIR iCUE LT100 Smart Lighting Towers Starter Kit, illuminating your room with diffused ambient lighting from 92 RGB LEDs that synchronizes with your system, games, and media.”

Initial Setup

Included with the LT100 Starter Kit are two of the smart lighting towers – one with an embedded lighting controller and one without, a cable to connect the units together, a micro USB to USB-A cable, and an external power supply.

The cables are of moderate length, with 1.5 meters (4.9 feet) for the RGB and USB cables, and 1.8 meters (5.9 feet) for the power cable.

The towers and bases are both constructed with aluminum, and while lightweight they do feel sturdy. The optional headphone hanger is plastic, and you have the option of more permanently mounting this to one tower using a supplied adhesive pad.

The bases have a polished edge chamfer that would make Jonny Ive proud, and the overall look of these components could certainly be described as ‘high end’. I will note that the white diffuser silicone has a tacky surface, and time will tell if this ends up picking up dust to any significant degree.

The towers install without wires or tools, snapping into place with copper contacts handling the connection between base and tower. I was initially concerned about the use of snaps considering this design allows for the reversal of the towers, but it is a fairly low-resistance connection and I expect that it will hold up to repeated use.

After pressing the towers into position on each base it’s a simple matter to connect the cables to each unit. The next step is to connect the included USB cable to an available port on your PC and run the iCUE software.

Controlling the LT100 with iCUE Software

Configuring the lighting effects using iCUE is straightforward, and while I did have to cycle the cables in and out of the second tower and re-run the detection everything showed up properly. I was choosing my desired lighting effects just a few minutes after putting the kit together, and overall the experience with initial setup was excellent.

After basic lighting setup has been attended to the options for LED effects are vast. Between the predefined RGB patterns, static lighting, and custom controls you can spend hours creating your perfect RGB-infused desktop environment (or just playing around). The LT100 towers respond immediately to changes in iCUE, and the colors from these units are vivid.

Dynamic ambient effects are certainly an interesting alternative to conventional RGB lighting, and as we saw from NZXT’s Hue 2 kit last summer, software-enabled dynamic ambient lighting effects for games and video content is a viable technology. I will say that incorporating the lighting controller in the base of one tower is a more elegant solution than the controller I taped to the back of my monitor for the Hue 2 review.

The video lighting was less effective than dedicated ambient lighting solution like the Hue 2, but these light towers don’t have a very large number of zones (and the diffusion probably doesn’t help). Dynamic effects are an interesting addition, nonetheless, and the audio lighting function – with the units facing the viewer rather than the wall – is more impressive.

Final Thoughts

While the iCUE LT100 Smart Lighting Towers are not going to replace lighting strips for most streaming setups (Corsair also offers the iCUE LS100), they are an interesting alternative to traditional LED strips for things like ambient display effects. If you aren’t willing to stick lighting strips to the back of a monitor, this is a no-touch alternative, for example.

I didn’t find the ambient effects to be as immersive as others that I have seen, but these haveo 46 LEDs per tower so I wasn’t exactly expecting the lights to mirror what was on screen anyhow. I ended up using the iCUE LT100 towers to tie in to my existing iCUE-powered lighting setup from the Hydro X Series loop I constructed for our review last year, and it offered a very noticable enhancement to my system – when the room lights were down.

Lighting levels are more than adequate when they are directed forward, but when they are reversed the white silicone diffuser results in ambient lighting quite a bit lower than the generic LED strips I typically use. I did not attempt to remove the diffusers, and I suspect that Corsair’s iCUE LS100 is a more appropriate product for my particular setup (throwing light against the wall as a backdrop).

This brings up the division between normal users and streamers. Video involves lots of bright lighting, and even moderate room light washes out the ambient effect with these towers. Face them toward yourself (or the camera), however, and they are very bright – but controlled (thanks again to those diffusers). There has to be a tradeoff, and it makes sense to position these as lighting accents.

Overall I found the iCUE LT100 to be a well designed product with typically outstanding software integration, as iCUE control was fully featured and left me with no complaints. If you like what these offer the asking price isn’t out of line with other smart lighting products we’ve encountered, and while these are more of a companion to LED strip lighting rather than an alternative, they still offer some interesting effects of their own, and are very easy for anyone to setup and use.

    LOL, WTF is happen!??! RGB has officially jumped the rainbow infused narwhal.

    I may be middle aged and over the hill, but that setup does look very cool and relaxing. When I get round to decorating the home office, I may well have to bling it up RGB style. It’s like taking mushrooms without having to take the mushrooms.

    If this works well with linux I could see myself getting this.
