What is the meaning of the abbreviation (LB) written at the end of T.I. Red?

Seen this also after green T.I. bombs.

Greetings - Antoon

LB = Long Burning


"some of the TI markers...are lnown as long burning T.I.'s and these have inly 20 candles ignited on bursting, a further 20 are ignited after 10 minutes abd a final 20 after four min utes. these T.I.s therefore are less brillant....but continue to provide the mark for a total of 7 minutes."
