Lancashire sent defending champions Leicestershire sliding to their second successive defeat in the t20 with an 11-run victory at Grace Road.
The visitors posted 154 for six after a rain delayed start, with Stephen Moore hitting a half-century off 38 balls.
But, despite a quickfire 36 from Abdul Razzaq, the Foxes could only manage 143 for eight in reply as Glen Chapple, Yasir Arafat and Steve Parry claimed two wickets each.
The Foxes made a poor start to the run chase, scoring only 10 runs in the first three overs and then losing the wicket of Ramnaresh Sarwan - caught behind off Chapple.
Jacques du Toit also fell cheaply and, although Josh Cobb hit 32 off 26 balls before holing out to long-on, the Foxes were behind the required rate.
Greg Smith trod on his stumps trying to leg glance and Rob Taylor top-edged to cover as the wickets continued to tumble.
Razzaq and Boyce injected some life into the innings with Razzaq clubbing two sixes, before being caught at long-off.
Boyce was out for 26 off 22 balls and the Foxes needed 20 off the last over to win but could manage only eight.
After rain delayed the start by half an hour, Foxes captain Matthew Hoggard had no hesitation in fielding first when he won the toss.
It paid quick dividends, Hoggard bowling the dangerous Tom Smith with a delivery that just clipped the off-bail.
And when Steven Croft carved a catch to White at point off Taylor with the total 28 in the fifth over, the Foxes looked in control.
However, a stand of 78 in eight overs between Moore and Brown put Lancashire back on track - with Moore posting his fifth half-century in seven limited overs innings this season. He reached it off 38 balls,
hitting four boundaries plus a massive six off Taylor.
But the young Foxes all-rounder had some revenge when he held on to a steepling catch to dismiss Moore for 58 off the bowling of White.
It was a big wicket for the Foxes and it took a lot of momentum out of Lightning's innings.
Brown, having made 24 off 26 balls, spooned up an easy chance to square leg to give White a second wicket, and two brilliant catches in the deep by Jacques du Toit and Matt Boyce took care of Paul Horton and Gareth Cross, who were attempting big shots against Razzaq.
A brisk unbeaten 20 from Yasir Arafat helped Lightning past 150 and, in the end, it was enough to give them their first points of the campaign.
