There are two revisions of the Dolphin Bar AFAIK
I own the first one and it has a hardware flaw where it powers the IR LEDs with too much current and they eventually end burning. Firmware updates were released to it and in the current version it simply doesn't turn the IR LEDs on if there's no Wiimotes connected to its internal bluetooth chip. While this greatly alleviates the issue of the IR LEDs burning, it's just a workaround since they're still being fed with too much current and long play sessions can still burn them.
The second revision is said to have an additional on/off switch on the back for the IR LEDs so the user can enable them whenever they want. I hope they also corrected the hardware flaw of the previous version by not overpowering the LEDs and making they burn prematurely this time.
If you happen to own the first revision of the Dolphin Bar with the updated firmware and also have some basic soldering skills, you can mod it to power the IR LEDs all the time and also can fix the flaw by replacing the resistors with proper ones so the IR LEDs don't end burning of being fed with too much power. I did that with mine (after having to replace 2 burnt IR LEDs and taking the stupid firmware update which introduced the new behavior)...
