60-Watt A19 Dimmable Incandescent Agro Plant Grow Light Bulb

A:  Correlated Color Temperature (CCT) defines the color appearance of white light. CCT is defined in degrees Kelvin; a warm light is around 2700K, moving to neutral white at around 4000K, and to cool white, at 5000K or more is considered daylight. Since the agro lite has a filter it does not properly fit into a CCT

A:  No, it's not too bright

A:  I think the question being asked if the bulb is as bright as a 60 watt bulb. The light the bulb puts off is normal, just like a regular bulb. I use mine in lamps where I have plants sitting on the table. Works great providing light and light the plants need to survive.

A:  No

A:  yes

A:  Grow lamps normally have an unusual spectrum and are not intended for "illumination" but more for the plant. As such, most plant lights do not specify this. Also, A19 incandescent lamps are not optimal for growing applications, unless you MUST fit it in a horizontal desk light, it is a very small plant, it can tolerate the heat of an incandescent and you don't mind paying fot 60 watts. This lamp (search this), "Philips 16-Watt PAR38 LED Grow Light Bulb", draws 1/4 the power, outputs way more light but no infrared. It is full-spectrum, it has a 5000K CCT and a CRI of 90+ (excellent light quality). Yes, you might need a different fixture but the results will be worth it!

A:  Since this not is a white light source (there is a filter on the glass) there is no correlated color temperature associated with this bulb and it is not possilbe to calculate the lumen count. It will have similar light output to a standard 60w incandescent bulb, although it will be slightly less bright due to the colored filter in the glass.

A:  I don't know why that info isn't on there, but, they only last a few months. I had mine hooked to a timer so it would stay on 8 hours and off 8 hours. It only lasted about 4 or 5 months. I next tried an LED grow light, it lasted about a year.

A:  I'm still learning about succulents. I plan on using these bulbs but moving succulents a little way away from the light. Remember the plants only need 8 hours a day of light.

A:  I have used it successfully with a large agave.

A:  Yes, and since it's incandescent, it does give off a little bit of heat which I find they seem to need. Just don't put them too close to the light, and monitor moisture since they will dry out faster.

A:  Yes it is good to provide supplemental light indoors for plant growth and also make them look good

A:  It has worked for mine, but, even with a timer, it doesn't last very long. Since my agro bulb failed, I have installed an LED gro light and it works just fine.

A:  It's a small bulb so wouldn't simulate enough sun power as those larger flood bulbs, but i found i made a difference in the dead of winter. Good luck

A:  Can’t imagine why not. Adjust intensity of light by adjusting distance from plant.

A:  I leave mine on for 17 hours a day. They usually last around 1 month.

A:  When used primarily during the fall and winter months, these grow bulbs have lasted for my indoor plants on average of about 4-6 months (more if not shaken). My plants require 24/7 lighting. I hope this helps!

A:  Months. It is worth every penny .

A:  Months of steady use. Worth the money!

A:  This time of year I have a lot of plants I have to move inside as I live in a Temperate Climate. For the ones in the house I change regular bulbs out for these. They usually last a good 2-3 months. That is with them on 24 hours a day.

A:  The rated lifetime on these is 1,000 hours. If on 24 hours per day, that comes out to about 41.5 days.
