BUZZ-Dialight: falls after trading update
** LED lighting company Dialight (LSE: DIA.L - news) down 3.1 pct after issuing an AGM trading update
** Dialight, which has been facing production shortfalls and order delays at its Mexico plant, says although it has taken steps to address issues at the plant, actions are yet to yield significant results in the fulfilment of outstanding orders
** Co says it therefore expects the group's results for 2018 to be heavily weighted to H2
** Investec (LSE: INVP.L - news) analysts say resolution of the operational constraints at the plant will be "gradual" but should allow Dialight to realise more of its "considerable potential"
** Investec: "However, the shortage of passive electronic components is still a problem" (RM (LSE: RM.L - news) : justin.varghese.thomsonreuters.com@reuters.net)
