I have just ordered one of these and thought I'd share my findings.
Was prompted to browse online for daylight light options having seen a deal advertised in Costco for a tabletop option for £49.99 by Philips. Granted, this larger one isn't made by Philips but is cheaper, I believe more useful, and has v good reviews. The same model is sold by alternative traders for £49.95 or if you don't mind black for £28.99.
There are more expensive models for £100+ but this still seems good value for money.
I hope this will be useful for doing needlework in the evening and also has health benefits as in the autumn months these daylight lamps are recommended for people who suffer from SAD syndrome.
