HumaPen Luxura HD is Eli Lilly's half dial durable pen. Each step on the pen dial gives half a unit of insulin, so  a patient can be given, for example, 4.5 rather than 5 units of insulin before a given meal. The pen is the last that remains in production from HumaPen Luxura range. The full dial  Humpen Luxura is supplied in two colours: champagne and burgundy. These pens, to our knowledge, are still in use and are thus discussed in this video. 

Clear insulins available in cartridges are Humalog, Humulin S (short acting human insulin)  and Abasaglar (Glargine).

Cloudy insulins are Humalog Mix 25, Humalog Mix 50, Humulin I, and Humulin M3.
