Recommend replacement for Acebeam EC50

I could use some recommendations for a replacement for my lost Acebeam EC50. I need lots of flood and no throw. Side switch almost a must have. This is a working light instead of a play light. I’d prefer inline 18650’s but a single 26650 is ok. Problem is these lights drag down a single 26650 pretty quickly when used on turbo and I have 18650’s laying all over the place. I also have a Convoy M1 with an MT-G2 that has a fantastic beam and color just not quite enough run time. Any chance I can get a longer tube and use it with 2x18650 instead of 2x18350’s? Long and thin is good, I don’t like soda can lights.

Thanks

I haven’t been able to find what I want either, hence the post. Dies anyone know where I can just get an extension tube for Convoy M1?

2x18650 tube for the M1 would be nice! I have a M1 with 70.2.

Emisar D4. It’s compact, so you have limited continuous output, something like ~500 lumens.
Haikelite SC02. Fat single 26650 MT-G2 for floody beam with great tint. Thick body for good heat sinking. I don’t consider Haikelite the most reliable brand, but for the money it’s really worth a try.
