The candles, which come with the name, age, date and place of death of a victim of the Holocaust, are to be distributed to over 50 cross-communal organisations and lit on the evening of April 11.
Sam Cohen, 46, from Finchley, north London, helped to co-ordinate the packing of the candles, on Sunday.
She said: “As survivors are dying out we have to find ways of remembering without them. You can look down at that candle and remember the person.”
Mr Harris said the project would see organisations distribute the candles to members across the country, in advance of Yom HaShoah.
Joe Woolf, of FZY, said the organisation had taken on 30 candles which would be distributed among its younger members.
“It is the simplest of ideas that make the most impact,” he said.
The 21-year-old said he was “moved to find candles with kids’ names on them as young as two”.
Anthony Gee, 52, who attends Radlett United Synagogue, said: “I’ve lost family in the Holocaust, I’ve traced family, I’ve found out what happened to them.
“When you pack up a candle for a one year old who died in Auschwitz it really makes you think.
“These are people and they need to be remembered.”
