I use a bedside lamp with a full-size Edison screw (I think E27 is full size). Daylight-spectrum bulbs are readily available in all manner of fittings on eBay. Last lot we got were 6x30W (equivalent 150W) with UK bayonet fittings for £5 each (though I don’t use something that bright for my bedside lamp).
