OORT SmartLED review: This is one dim bulb
This bulky bulb is bigger than most, but at least the traditional shape lets it fit into most fixtures without too much trouble. As with the iLumi, it's a Bluetooth-only bulb and it requires no setup or pairing; the app does all the heavy lifting. OORT works without an account, though if you later opt for the OORT SmartHub (not yet available) for home automation, the bulbs can be integrated with that system. The hub can connect to your Wi-Fi router, giving you remote access to your lighting system.
Range is downright terrible--about 12 meters in my testing--but on the plus side (and unlike the iLumi), the app does realize if you're out of range and won't erroneously report that a turned-off bulb is actually on and vice versa. OORT also creates a Bluetooth mesh network where each bulb functions a node that can relay commands to nearby nodes, increasing the entire network's range.
Once the bulb is connected and the app is activated, it's a trivial matter to locate nearby bulbs and start interacting with them. But compared to other bulbs in this roundup, its configurability options are limited. A standard color wheel lets you set the hue, and an internal wheel alters brightness. Curiously, there's a separate button to activate "white light," but this white light is anything but. Rather, it's an extremely cool color that I can only describe as an uncomfortably bright purple. The app also features a button for setting color temperature of your white light, but this is grayed out and has no actual function. My best advice is for actually tweaking white light is by using the regular full-color wheel to approximate a useful white color temperature, although even that results in some iffy color tones.
Special modes include a handful of presets for reading and "love" (ahem), a sleep timer, a dance mode that cycles through random colors, a neat "snore" mode that raises and lowers the brightness in regular intervals, and a flashing/slow strobe setting. A simple timer system is also included. Dimming is smooth, but the bulb isn't really bright enough for dimming to matter much anyway.
The OORT SmartLED has a number of limitations, but the biggest remains its sheer lack of brightness. At 180 lumens, it's the incandescent equivalent of a 15-watt bulb, which is less power than a typical refrigerator light bulb offers. In a home environment, a bulb like this is really suitable only for accent lighting, at best.
