i am wondering if the LEDs give out UV and that is why the bulb is opaque (probably not).

i hacked the chipboards off a couple phillips 8.5W 800lumen bulbs. i want to know what Volts and Amps the array uses and each LED individually so any bulb can be hacked and put on better heatsinks and driven with a different (possibly better) power supply.

Nice report

Several years ago, some of us used similar led globes (with/without) diffusers to very good results. You can probably find mine in the archives

Better to use spot lights which direct all the light to the canopy

Also I have only seen 5000 or 3000k in big box stores, BUT, Amazon has 4000-4500 which are neutral white

Just because you weren't taught something doesn't mean it's not true, and vice versa

thanks for putting in numbers what many of use 'suspected' even a cheap led bulb outperforms a bigger cfl

and the lens/diffuser REALLY makes a difference! ive always broken them off before even turning them on because it makes sense, but wow!

I was just perusing walmarts lighting. Seen some different led bars and the bulbs you tested. I think I also seen an led floodlight or security light this may have potential. Thanks for taking to time to not only do the science, but also.offering your results here for us in such detail

CFL puts out light in more area (all around the bulb) than the LED.

I found these bulbs at Wally World. They're slightly less than $5 per bulb.

I removed the lens and found this inside.





I doubt anyone would actually remove the lens and keep this reflector in place, but what the heck let's get some light measurements lol.
