CRI & startup delay? What is the CRI for these bulbs.How much time do they take after powering on to reach their maximum brightness?Thanks

Take their specifications with a grain of salt, their wattage ratings are completely off, who is to say they aren't fudging the numbers elsewhere?

I've tried but don't notice much if any of a startup delay. I'd say they are at nearly 90% brightness instantly.

CRI is 91. http://www.alzodigital.com/online_store/full_spectrum_light_bulbs_45w.htm

I've never timed it, but I've never noticed a long lag in them warming up, so I'd say not long at all. I haven't had onex, but these are extremely bright. Bright enough that I'm sure it bothers people who get my lights in their eyes. The only thing that matters to me, is how long these last. I had to replace my first ones (not maxlux) after 6 months. I've had these for a couple years already.

I can't find CRI anywhere on the box or bulb but it does have a scale for light appearance. It is almost at the end of the "cool" side and says 5850 K. I was also trying to figure this out because I need bulbs for some plants. I see that they have another one for plants that are full spectrum. So far, these have worked great for me. I have replaced most of the bulbs in my lamps and it is so much better than the other, cheaper CFLs that I was using. You also can't beat the price since they CAN be used in regular lamps instead of purchasing expensive OTT lites. I do a lot of work that requires me to see colors accurately and these do the trick.

I have two setup, both on CF bulbs. I have 8 bulbs on one circuit, and one of the bulbs I noticed flickers for a few minutes after you turn them off. Something new I found out, when the power goes out, then comes back on, the lights on these units come on with the power.

Hi I never got that far as to seeing if they are as bright or brighter then standard bulb, because while inspecting the fit and finish of the wiring connectors I noticed inconsistent quality. The heat shrinked connector joints were done one was done properly and the other was not even close. So I did not want to even risk it.

I'm pretty sure that the minimum increment of on or off time is one minute. The maximum on time is dependent on your bulb life.

Hard question to answer with any authority, as it depends on if the LED bulbs themselves are dimmable... but the short answer is yet. Now, with that said, be aware that LED's generally go from 0% brightness to 15-20% brightness in the first step... just the way they are made I guess.. but once turned on, they can be dimmed to very low light levels..

Hello Mr. Curtis. I bought these a while back and found they make your headlights "whiter". They have a very light hint of blue. These ARE NOT even close to HID intensity. They are slightly brighter, but not significantly. I would try Phillips Crystal Vision bulbs. They are about as good for 35 rather than 50+. I bought them and had them burn out within several months after use... I'm not sure if it was something I did or if it was just a bad batch. A friend of mine also had some really good luck with ebay bulbs that were "XEON" or something like that.Here is how they looked in my car: http://www.cardomain.com/ride/3965245/2003-hyundai-accent/photo-gallery/ Hello Mr. Curtis.

I do not know the cri but I would call it a "soft white" bulb. All home furnishings look natural in this light. I believe the color temperature is in the description. In a tall fixture pointed at a white ceiling this bulb emits far more light than a 100 watt incandescent flood lamp, and more than a 100 watt equivalent spiral fluorescent...bulbs I tried previously. There is a 1/2 second delay on bulb startup, but it starts up @ full brightness. I STRONGLY recommend this if you prefer a soft white or warm white light. 2700 degrees is rather warm compared to cool whites or sunlight bulbs. I love this light in my living room.

Well, I don't know much about CRI but in the bulbs attached reads 85W, 120V, 5500K RoHS, they are big bulbs, i had to replace with 3 bulbs as they got broken, my mistake but replaced with smaller others and have worked fine, i bought like a year ago and i am happy with my lights.

Hi, Wanted to let you know like all new LED lights its hit and miss I think we've only had one bad but it happened almost immediately I cant give you an hour length because with all LED lights it just depends on how well the bulb was done.That being said they last a long time for the price.

Yes...I would echo what Rob said. I've been amazed at their longevity. I have them on a timer running about 5 hours EVERY night for the past two years. Only a few bulbs burned out...the other ones are losing their blue color finish due to exposure to sun/rain. Great bulbs.

Hello Light waves, With no spec for lumens or CRI on Amazon, I'm almost as much in the dark (NPI) as you. However, I've had one of these running in a decorative spotlight for a few months, so I can make some comments. The color of the light is much better than a CFL, but not as nice as incandescent or the legendary Philips L-Prize bulb. Comparing it with various Philips and Cree LED bulbs that I'm currently using, I'd say the CRI is probably around 80, certainly no better than that. That's just an eyeball estimate though, YMMV. Brightness is roughly equivalent to a 25-30w incandescent bulb. If you use it in a reflector spotlight (I'm using it in an old boat searchlight - the reason I needed a bulb with a BA15D base) it makes an odd but interesting pattern on the wall because of all those individual LEDs spread over a large area. It doesn't dim very well, even with a PWM dimmer specifically for LED lights. However, after my initial experiments, and given it's modest light output, I never attempt to dim it anymore. You probably already know this, but just in case, be aware that this bulb has a BA15D (both bayonet pins at the same height) base. This means you can put it in the socket backwards and it will not work (I've done this a few times, it didn't destroy the bulb). Many bayonet base LED bulbs on the market use the BAY15D base (pins at different heights), preventing it from being inserted backwards. I have found the descriptions - even on Amazon - to be wrong about the base type occasionally, so always look at the pictures carefully to be sure the base type is what you need.

My bulbs appear to have the same brightness, except for the one that only lights up when you have it on night light setting. It lights up yellow when activated by itself.

Yes there is a delay of about 1/2 second. I don't find that it's a problem because the light shows up bright immediately. Compared to a cfl bulb which takes a lot longer to turn on and to brighten up, the LED bulb is a great improvement.

I didn't measure the power used, so can't comment on that. But mine are *really* bright and I believe the claim that they are equivalent to a 225W incandescent. But they're not instantly bright - they take about 5 minutes to reach full brightness.

They come on quickly but, like lots of other fluorescents, take a few minutes to get up to full intensity. I would say they are a bit faster then some other bulbs I bought in getting to full brightness .
