Don't waste your money, that's all that "LED" will be.
Buy a Thrunite TN31, don't know how they'd be for dags (someone will have to take one for the team there, I don't got a dog) but for I use one for spotting and I leave the LF at home.
On the LF front, I've a HID conversion kit in the post from Oz, not arrived yet due to Christmas etc. Told it will draw 1/3rd of the power of a 100W bulb and give better distance. It, however, won't dim, takes 15 or so seconds to get to "full" power, but quite bright by 5 seconds. So, not for everyone.
