Thanks for the email, at present we have managed to get two of the Glowstars out to Goa.  This is just the glowstars themselves and not the solar panels.  Once we get a solar panel out we'll probably 'lend' one to the slum as long as they will use it properly.  The two we have at present are just used when the power fails.  We had one on all night last night as we had 3 children stay the night and it was used as a 'night light' for them as it was their first night in the house. 
Thank you so much for them
