Since I guess I wrote most of the answers, I guess I can answer this, even though I no longer work for Securifi.
The Almond+ (and Almond 2015) only supports ZigBee HA.
That said, most of the ZigBee LL bulbs have something known as ZigBee HA fallback. This means that they will work with a ZigBee HA controller/gateway and ZigBee LL controllers.
This is a confusing aspect of ZigBee and something that wasn't made properly clear. ZigBee 3.0 should remove all of this, as ZigBee HA and ZigBee LL will become a single standard.
Just keep in mind that Philips bulbs can't be manually reset, unlike all other ZigBee bulbs that were tested while I worked at Securifi. You can only pair new, single Philips bulbs, as the bundled bulbs are already pre-paired with the Philips controller and as they can't be reset, they can't be paired with other controllers. Philips have some semi-functional software that allows you to pair them with another Philips controller, but that's it.
I'm not aware of any bulbs that don't have HA fallback, as I managed to pair Philips (not recommended as per above), GE, Osram, Sylvania, Belkin and Cree bulbs just fine. Never tested the LG bulb, but we also had some other no-name products working. Not all worked perfectly, but hopefully most of that has been fixed since then.
The hope was to be able to support multiple ZigBee profiles, but it was too complicated to switch ZigBee profiles. Regardless, you shouldn't need ZigBee LL support to get the various lights working.
