well out of the two i have the Agir Brokk 21w as the main torch and a Halcyon 10w for my backup and neither has really screwed up i had a small problem with the Halcyon that UE in Portland sorted the same day
Both are as good as each other but i do like the Halcyon kit

and at the end of the day you pay for what you get. buy cheap pay twice !!
