    Alpha problem / battery sensitive??

    Dented cells anodes should work fine, as long as they long enough to make contact. You can get a magnetic battery spacer(4mm X 1-1.5mm round) for the cells that are not long enough. GL

    Alpha problem / battery sensitive??

    Thank You for your input 🤝 . The new ICARUS driver in your Ready Made is capable of drawing 3.1Amps of power. Many 18650 cells in circulation for sale are not rated for the 3.1A of discharge on Maximum burst mode. The driver can function flawlessly with your older EDC cells on all levels <80%...

    Replacement Preon P1 (Original 2009 model) push button tailcap.

    I do not know the source, but The legacy Preon switches were press fit into the tailcap. There were modder's who could make a new outer switch cap that made accidental activation and tail standing a thing of history. I would pursue any tail cap switch. You can take the old switch out of your...

    New Mini MKIII's for 2021

    Hey Gang, Well I actually have good news, how about that! We received the shipment of replacement pills last week, have inspected them, and are getting started on reworking 1100 lights. That's 200-250 hours of labor on our end and we plan to start shipping next week. I've spent the week making...

    6V "Lantern" Battery Lights - History? Anything good?

    Wiki lists the lantern spring battery capacities are between 14-26 Ah. They do list 908AC/C and 908CD/D in the NEDA numbers with seven different Manufacturer designations. I run a 4 D cell converter using the new rechargeable Lion 1.5V cells. I'll get some pics together.

    Anybody try Quark QK2A MKIII on a single AA body?

    0.9-3V for the QK2A head. Works well with a single AA tube, with less maximum output. NiMh cells are preferred and well. I also have used the QK16L head with the AA tube and a 14500 cell.

    The 519A has 5% higher CRI with about the same output as the 4K 319A.

    Help with troubleshooting Delta

    Did You get it fixed? The Delta's ICARUS driver requires a HD 5C 18350 cell delivering 3.4A on maximum setting to function properly as designed. Will the light stay on in Low or Medium, or does it flicker? Have You tried to verify the switch is fully tightened into the tailcap? All that is...
