New Rechargeable Lightbulb

All these rechargeable globes uses the same no name battery just with different branding.

Repaired a couple already and today another 2 x 9w ACDC branded ones bought 5 months ago. The oke did not want to take it back again since this was the second set he received since buying it so he just got some proper cells.

Underneath the shrinkwrap

Weight of the cell

Weight of the new Samsung 25R replacements

BMS used

Fully charged after resting for a bit before capacity test

Been testing for a while now

Capacity test done :ROFL:

What does the light look like? How do you open it?

If its all the same which brand would you recommend or just going for the cheapest? The prices vary significantly

ive posted pictures before on this thread i think .remove the dome .unsolder the 18650 ,or whichever size they used sometimes a 18350 ,solder a new one in ,then throw away because an led has also popped or look for the black one ,remove it solder over the 2 posts and reuse for a while .you end up replacing a R60 battery in a R70 globe .

I don't think so. Some brands are terrible. Others last a very long time. Aurora and Eagle lighting are 2 of the best ones that I have found so far.

How do you spot weld the new 18650 in place? Any easy way of doing this? Do you use protected or unprotected cells?

Do I use The Force to remove the dome?
 
Is there a way of knowing what size battery is I did without opening it
 
been real busy sorry i did not get time to visit here. I just twist open the dome some are glued and then use a small prying tool to open it. Battery just plugs in on the pcb. Wire is crimped on a little tab and is spot welded.

I use this then spot weld new nickel strips to the battery and spot weld them to the BMS. I solder the old wires on the bms then just plug it in again.

What does that mean

the lamps have a limited life .by the time the battery has died the charging circuit is also wornout and the leds are fried .a new battery will give you time to get another but its not a long term fix .lamps are not much more than a battery .its nice to fix them but totally uneconomical normally unless you have access to a spot welder .if you have a decent soldering iron like a Magnum you can solder them but run the risk of overheating the cells .
 
Had to repair another 2 same brand (Lightworx) with different batteries chinese QC :X3:. Only 1 with a label 1200mAh and some nice double shrink wrap. Test showed a massive 443mAh impressive batteries :ROFL:

It looks like they are getting really hot, I don't think that is good for the battery.

Totally agree. They do get hot in that enclosed space but since i opened the vents that should have been opened in the first place the bulb is waaaaaaaaay cooler previously you could smell the plastic/heat.

Designed obsolescence is a pet gripe of mine. With respects to light bulbs there's apparently the (in?)famous Philips Dubai LED bulbs that you can't get anywhere else. From what people say Philips was mandated by their monarch to make longer lasting more efficient LED bulbs, or get out. So they made them the way the UAE wanted. Of course the margins are much lower for Philips, but it's still better than selling nothing in an entire country.

Not sure how true it is.
 
I've picked up PnP branded ones for like R85, lasts for like 5 hours. Only gets dim for the last hour.

It's not the brightest at the best of times though, it's like a 40w equivalent bulb
