Me too. The silver MT03 is gorgeous. Luckily the driver is easy to replace; that’s why I’m still interested in Haikelite. But now seems to be a bad time to get this light unfortunately.
My silver NW showed up today, charging up a fresh set of 30q’s to do a proper test. No flickering so far on two different sets of protected batteries as well as a half charged set of 30q’s. It did start to flicker on high on the one set of protected batteries after a mode change but after cycling through the modes to low it went away. There was a bit of audible driver whining too. I’m blaming that on the five amp protection circuit those batteries have. I tested it on my power supply just holding the test leads in place with my fingers, no issues running from 7.3 to 8.5 volts, it would flicker a bit if the ground wire wasn’t pressed hard enough. Amperage does increase with voltage, you can see the beam brighten a bit even on low. It draws around 8 amps/60 watts on turbo.
The level spacings are fine and the tint is nice, matches the NW MF01 when wall hunting. Smooth floody beam, wider hotspot than the MF01 and a good amount of spill. The only thing I have to gripe about is the tailcap did not thread on smoothly. No grease on the threads or behind the contact board. Also the solder joints on the guide pins were a little to big for the groove in the tailcap. Five minutes to disassemble, do a little filing, apply grease and reassemble. Works perfectly now.
Hope Haikelite takes this unfortunate issue as chance to show their strength in customer support. It could be battery quality/length or contact problem that might not be completely their fault. Those who buy this high wattage light should know it can have issue if certain things are not in good condition.
