METERS & GAUGES
for Cricket Umpires and Groundsmen

2016: Acumen are pleased to announce a LIGHT METER
high accuracy, data hold
tested by several umpires
20+3 UK p&p.



Initially Light Meters were supplied to TCCB by manufacturers, Megatron Ltd, London, N19 4NE
Their model ULM was approx 150 each inc P&P & VAT-
BUT that company has ceased trading.
HOWEVER www.Megatron.co.uk says that much of their business has been taken over by
Optical Test and Calibration Ltd, Bradford, BD7 1HR - visit www.OTC.co.uk

There is no specified light level for recreational cricket. Initially umpires should make a subjective judgement and then take a series of readings. You will subsequently be able to determine objectively whether the light has improved or deteriorated.

George Temperley kindly advises me that ECB use SAMPOLX1332B available from Useland via Amazon at 36.90 but it is not clear whether these include a calibration certificate as required by ICC regulation paragraph 3.62
