I broke down and ordered the E03H XPL too. I really wanted the Nichia but that sold out quickly.
Still, an AA angle light with magnetic tail, unique built-in diffuser, and regulated output is just so practical for close-up work and too tempting to pass up at clearance price.
Mine just came today. Really nice quality little light. Good clip, good headband, strong magnet, so lots of attachment options. Got the nichia 219c and comparing it to the Tool AAA nichia 219bt I think I really like the Tool better. Maybe the tints are just different but to my eye the B is a little whiter and cleaner.
It is very common for users to find the tint of the 219b preferable to the 219c, mainly due to a lower duv value. Differing color temperatures may also play a role in your preference.
No doubt a Manker E02 body with a 219b emitter would have been really well liked by many users.
