Review: Bedtime Bulb E27 LED (2200K, CRI95)

I will waiting for you after about 12 month for new order of REMEZ (R.) :smiley:

In your calculation something wrong…

So, 5pcs R.9 cost from me 5x8+6$=46$
5pcs S.8 cost from me 5x21+6$=111$ (real price for shipping for me much more, because of weight)

That’s why I ordered the 3 “spares” to put in my bathroom. I can steal from there if I have some die in the office. Even with bad luck, they are still a better value.
5pcs R.9 would be $46, but you had to cancel that order because of flicker issues on 120v. So R.7 was my only option. And yea, there is a less efficient S.8 option for $111.

Are there any more UK users in here? I would appreciate help from a few more people to establish statistical significance (for the UK only).

The deal is:

  • We send you a Bedtime Bulb (either E27 or B22 base) for free
  • You observe it for a few minutes to see whether the light is steady or has any fluctuations
  • It’s yours to keep afterwards

If you are open to helping me with this and are in the UK, please send me a PM.

Thanks,
Greg

I have now used and observed the Bedtime Bulb in three locations in southern germany and wasn’t able to notice any kind of fluctuation.

@yeutterg, if you still need more testers in the UK, just post your free bulb offer over on the BLF Deal Alert thread. THAT will get you some PM’s. :partying_face:

Thanks!

@ikkentobi Awesome, thanks for that feedback!

I have now used and observed the Bedtime Bulb for good few minutes and wasn’t able to notice any kind of fluctuation:

I really appreciate the warm feeling I got when using this bulb :+1:

@rost333 Thank you so much!

I received one this morning, and had it on for a few hours this evening. Absolutely no fluctuations noticible to me.

Should visit Help me find a Nice, Warm, Night Light , as there’s a dearth of flicker-free nightlights, too.

Woody, that’s great to hear!

Lightbringer, thanks I’ll check it out!

So from following this thread, it appears to me the ‘flicker issue’ is most likely fluctuations in voltage coming through the bulb’s AC/DC converter.
Power fluctuations actually happen often even in the USA, but it seems all devices except LED bulbs have enough capacitance to ride them out. There’s just not enough space or value to get fancy with the electronics in an LED bulb.

Though, if I spent $20 on a premium light bulb for bedtime use that scares my brain every time the power fluctuated, I would wish I just bought a 80 cent halogen.

Hey Josh, you’re right that we have some fluctuations in the US too. But our circuit handles it pretty well in the US.

Europe has a slower 50hz AC frequency that may require extra capacitance to ride out the longer starvation period.

Not on my block. We’re at the end of the line, pretty much the worst hold-up around. The guy who runs a huge saw on the opposite block will dim the lights here when he powers it up (inrush current).

You want to put a bulb to the test in the US, try it here. :laughing:

Well, we were planning on redesigning the driver anyway for both North America and Europe, mainly for better dimmer compatibility. This is just accelerating that!

Tested for a couple hours the past few nights and didn’t notice any flickering whatsoever. Really nice cosy warm light :+1:

Same for me!

Thanks hodor and finges for the feedback!

Based on the survey results so far, we haven’t noticed any issues in the UK. The most likely plan of action is to continue to sell there. Meanwhile, we are working on a new driver for all bulbs (US included) that fixes the issue in Europe and gives us a wider dimmer compatibility. It will be a while before this is ready, but I thought you would appreciate the insight.
