Does adjusting the brightness of the light bulb mean lower power usage?

On the brightest setting, they are not that bright. I would think in the description it should tell you the usage.

What's the actual wattages ratings ? It claims to output light equivalent to 75watt.

11 watts of draw. Prisma 1050 have 75w equivalent output (1050 lumens). Prisma 800 have 60w equivalent output (800 lumens).

    Great lights

    Just discovered that if the power is off for 2 hours you have to rediscover them in the Geeni app and then reactive and add them back to your Alexa routines.

    Measure bases

    I originally meant to install these in my overhead lamp, I didn’t measure the base so now they’re in the bathroom instead. Overall, I think these lights are pretty neat. They can saturate themselves to generate more light, they can change to any color, they work with alexa and if you left them on, on accident? You can remotely turn them off. This paired with scheduling (activate when it’s dark [or temp drops in your area] for example) makes it worth it to me.

    Good value for the money

    This is my 3rd brand of smart bulbs. They were on sale is why I purchased. Nice colors. My only disappointment is I can’t have these bulbs respond to music. Maybe I’m doing something wrong but the other bulbs I have purchased have that ability.

    Really good, does not require a hub

    I had a few requirements:
    1. Did not want a hub. I wanted my phone to function as a hub. Don’t want microphones listening to me all day waiting for me to turn on the lights. Setting up the first bulb took a minute, the others were easy from that point on.
    2. Needed them to keep their settings even when physically switched off. These are great for that, you can switch off power to the bulb all night, turn it back on, and it remembers the settings.
    3. Needed to be bright, warm, and have a full range of colors when desired. These met all those requirements.

    These coordinate with the same brand smart light switches, which is also neat. You can build logic on your phone that allows the switch, without any power connection to the light bulbs, to turn the lights on and off. That is a neat trick. ‘If switch = on, turn on lights,’ is basically how the logic works. That allows you to have a physical switch in addition to using your phone to turn the lights on and off. Very nice. I give these high marks. I have only had these a few weeks so I cannot speak to longevity. I can say all four bulbs worked fine right out of the box.

    Safer home and ease of mind

    Extremely easy set up! Using these with Alexa and we programed random turn on times to be used if we are not home. Along with security cameras these items are a must. Plus you can change the colors to fit your mood! LOVE IT!

    One was defective

    Watch yourself when it comes to these “value packs” as one may be defective. I had one defective and I found that out after I the return window closed. I tried to contact the company and was given the runaround for weeks. Finally I just gave up. Be sure to test all bulbs before your return window with Amazon closes so you don’t get stuck with a bulb that is DOA.
