Dialight shines

The spotlight remains on Dialight's key lighting division. Sales surged by a half to £100m as it launched new products - including a 60,000 lumen replacement fixture that uses half the energy of traditional bulbs and lasts upwards of a decade - and struck deals with influential North American distributors. Management expect further gains as the use of LED lighting in mines, warehouses and power plants remains in "very early adoption stages". However, the division's operating margin slid by 2.3 percentage points to 14.5 per cent as industrial action in the US left Dialight little choice but to fly components in.

Turnover also dipped at its signals division as traffic revenues fell a fifth. But sales rose 22 per cent at the segment's obstruction business - which supplies warning lights for communication masts and wind turbines - as telcos and broadcasters raced to retrofit their towers.

Broker Investec Securities is reviewing its forecasts. It previously expected pre-tax profit of £21.9m, giving EPS of 47.1p, up from £16.8m and 36.2p in 2014.
