Young offenders will be ordered to go to bed early under strict new rules announced by the justice secretary.
Chris Grayling has announced that 15-17 year-olds in English institutions will have to be in their cells with lights out by 10.30pm.
"In some prisons young people are allowed to go to bed when they please. I don't think that is right. Stopping this inconsistency and introducing a strict 'lights out' policy is all part of our approach to addressing youth offending," the justice secretary said.
Teenagers who refuse to obey the new rules will be penalised and lose privileges such as access to a television.
More than 800 under-18s are serving custodial sentences in young offenders institutions.
Mr Grayling said: "It is also crucial that young people, most of whom have had chaotic and troubled lives finally get the discipline so badly needed to help turn their lives around.
An offer of sunscreen to inmates who climbed onto a jail's roof in hot weather was "foolish", the prisons minister has said.
Jeremy Wright said that he has ordered an immediate review into the matter.
"This should not have happened," Mr Wright said.
"There should be no policies in place which promote this kind of foolishness and I have ordered an immediate review of this incident to ensure that it does not happen again."
Two prisoners who climbed onto a jail's roof in hot weather were offered sun cream by staff "in line with health and safety rules."
The duo turned down their offer during the incident at Dartmoor prison earlier this month.
It is not clear how the inmates managed to get onto the roof or which building on the Devon site was involved.
The Ministry of Justice said the suntan lotion offer was due to health and safety rules.

Prisons Minister Jeremy Wright has said the current system for allowing prisoners out on temporary licence is "too lax", after a murderer and a robber failed to return to their prison in Liverpool.
Wright said he will make "major changes" to address the shortfalls in the system.
He said: "There will shortly be significant restrictions on who is granted temporary release – which from now on must be earnt – tightening up of monitoring arrangements and abolishing any leave without a clear link to rehabilitation."
More than 50 inmates reportedly took over part of a prison wing. The incident broke out at HMP Northumberland in Morpeth at around 7.30pm yesterday.
Prison Officers Association general secretary Steve Gillan told the BBC that there was a stand-off. He said last night: "We do not know what has sparked this major incident, but I do know that 50 plus inmates have taken over a wing," he said.
"We have teams from other establishments trained to deal with riots on their way. There is concerted indiscipline and our officers will try to contain it."
A spokesman for Sodexo, which operates the prison, said the situation has now been resolved and an investigation is due to be carried out into the incident.
