Wow!
Honestly I didn't think this LED bulb would be bright enough for the basement application for which I made the purchase. I was way wrong! Not only does it give much more light than I thought, it throws light into another area where we needed more light.

If it lasts I'd buy it again!

Bright Bulb
I have 6 recessed lights in my shop and replace 2 with these bulbs. The ceiling is 10’ and they help brighten the shop a lot making it way easier and more comfortable to work. I would highly recommend and am glad I bought the stronger lumens bulb. They do stick out of the can quite a bit but I was able to find a ring to give it a more finished look.

I installed these bulbs in my shop and the light is terrific. I also like the bulbs with a shroud to direct the light downward.

If the reflectors were separate I would have ordered them but because the bulbs with attached shroud forces a more expensive option when it is time to replace (bulb and shroud together) I ordered just the bulb. I will make my own shroud if needed.

What are the dimensions of the bulb, specifically how far does the bulb extend from the base of the socket?
Joseph s on Nov 6, 2016
BEST ANSWER: I measured the 2750-lumen bulb (150-watt equivalent) at 7 1/4 inches long and 4 inches in diameter at the widest part of the glass globe. The heat sink (silver colored metal part, is about 3 1/4 inches in diameter at the broadest part and only slightly less-- about 3 1/5 inches where it begins to narrow before entering the ceramic base--which means the bulb is very fat compared with conventional bulbs and will not fit in many typical lamps or other fixtures. I squeezed my bulb into a conventional, clamp-on-type, aluminum-shade work light, but the tip of the base only met with the metal-tab-contact after I'd bent the contact out a bit to meet it. The 14-oz. weight of the bulb and the 7 1/4-inch length make it too cumbersome for a light work lamp, so I'm saving the bulb for a future use.
Will this work in a three step socket (i.e. is it dimmable)?
Ollie on Nov 9, 2016
BEST ANSWER: Any bulb will work in a three way socket. You will only have one position that will energize the bulb so you have to click the switch multiple times to turn it on. I would just function the switch twice when I turn the light off and it is ready to turn on with one activation of the switch. Have been using a LED bulb for half dozen years now without any problems. Put in a larger LED for more light and less energy consumption.
Will this bulb fit in an outside fixture beside a door entrance?
John v n on Nov 19, 2016
BEST ANSWER: Without knowing your type of fixture, its dimensions, configuration and other relevant information specific to your situation, that would be a difficult question to answer. However, the base is designed to fit into a standard light socket.
How does it work in the cold?
Lorne S on Nov 20, 2016
BEST ANSWER: Manufacture has an operating temperature of -4~104 degrees Fahrenheit for both bulbs on the product specifications
how do's lumens compere to watts?
Bruce M on Oct 29, 2016
BEST ANSWER: Roughly 16 Lumens/Watt for an incandescent bulb.
are these daylite or soft white?
greg c on Nov 21, 2016
BEST ANSWER: Taking the exact science out if it and just going by the old eyeball light meter (i.e. your mileage may vary :)), I would consider these to be well toward the "white" end of your question. It "feels" very much daylightish to me (which is great for my purposes—I love it. Even if I put this light on during daylight, it still feels bright. Makes my flourescents look yellow in comparison. Hope this helps :)
looking for a bulb equal to 200 or 300 watts?
Bill C on Nov 27, 2016
BEST ANSWER: A typical 100 watt bulb is 1600 lumens and a 150 watt bulb is 2600 lumens (it looks like it is not a linear comparison). The 2570 lumen model in this bulb would be roughly equivalent to the 150 watt bulb. The 4275 lumen model of this bulb should be in your 200 -300 watt equivalent range.
Can this bulb be used in an enclosed fixture?
Tom A on Nov 27, 2016
BEST ANSWER: After consulting with the manufacturer, these bulbs are not intended for use in fully enclosed fixtures. Adequate air circulation is required around the heat sink. Each installation is unique, and any installation other than the type shown in the illustrations should be evaluated by a qualified electrician prior to installation.
what are the dimensions, e.g. Max diameter, length from socket tip to end of the bulb, weight. Some people may have enclosures, or space limitations, and we can see the size relative to a hand so we know it's larger and heavier than a standard bulb?
D B on Nov 20, 2016
BEST ANSWER: Okay, since you asked (this is probably more than you want :)?)…

I’d feel confident in these measurements being within 1/32” and 0.1 oz.

4275 Lm. bulb:
-------------------
Total length from tip of electrical contact: 9-3/4”
Length of Edison screw section (the whole portion which is the diameter of the Edison screw, up to the larger diameter plastic flange—i.e. not just the threads themselves): 1-1/8”
Glass diameter: 5”
Glass section length: 3-1/8”
Heat sink section total length: 3-5/8” (starts 2-3/16” from tip and goes to 5-13/16” from tip)
Heat sink diameter: 4” tapering to 3-3/4” straight, then curves down to 2-13/16”
Weight: 23.6 oz.

2570 Lm. bulb:
-------------------
Total length from tip of electrical contact: 7-5/32”
Length of Edison screw section (the whole portion which is the diameter of the Edison screw, up to the start of the curved plastic section—i.e. not just the threads themselves): 1-1/16”
Glass diameter: 3-15/16”
Glass section length: 2-5/16”
Heat sink section total length: 2-9/16” (starts 1-13/16” from tip and goes to 4-3/8” from tip)
Heat sink diameter: 3-3/8” tapering to 3-1/8” straight, then curves down to 2-1/2”
Weight: 14.6 oz.
how do I get replacement under warranty of the LED Big Bulb? What is the warranty?
Dave C on Jan 13, 2017
How Hot does the Lamp get?
Howard K on Feb 19, 2017
BEST ANSWER: With a digital thermometer that has a metal probe (designed for cooking), I measured the temperature of the hottest part of the 2570-lumen bulb, i.e., the heat sink (the fluted metal between the glass globe and the screw-in threads), and I found it to be 150 degrees Fahrenheit in a room that was 74 degrees Fahrenheit. This measurement was done at half an hour after the bulb had been on. At that temperature, I could tolerate touching the heat sink for less than a second. Still, that's cooler than a 150-watt incandescent bulb, which would be intolerable to any touch. The glass globe of the LED bulb was only lukewarm in my cupped hands, and the metal conical shade that was an inch above the base and flared further away from the bulb as the shade extended outward was still cool.
Can these builds be used in Australia?

How many amps does it use and how does that compare to a 100W incandescent bulb?
Boyd C on Mar 12, 2017
BEST ANSWER: The two available bulbs from Rockler are 30 and 50 watts. They are much brighter then a 100 watt incandescent light bulb. One bulb has replaced three two bulb fluorescent fixtures.
Which bulb recommended for a 2 car garage/shop with 8' ceilings?
luv2flyfish on Jan 24, 2017
BEST ANSWER: It somewhat depends on your age. At age 40, you need 3 times the light as you did at age 10, and by age 60, you need 10 times as much light as you did at age 10. Regardless of your age, bigger is better, and you won't regret getting the larger LED bulb.
will this fit in a recessed fixture ?
Terry R on Jan 1, 2017
BEST ANSWER: Probablly not they are huge and likely generate too much heatt
How much heat does this put out? I have a 100w bulb in a reflector that I use close up for lighting the inside of pieces I'm turning on a lathe and it generates a lot of heat. I'm looking for something that will shed a lot of light but not the heat.
MARK C on Nov 29, 2017
BEST ANSWER: LED bulbs by design put out more light for the same wattage as an incandescent light. This particular LED bulb puts out about (my estimate) the same amount of light as a 150 watt incandescent light and be warm but not nearly as hot.
Is it dimmable?
Vic B on Jan 3, 2017
BEST ANSWER: I Do not know. I use it in my basement & garage. They replace the standard 60w incandescent installed by the builder. I Love them.....especially with shrouds in the garage w/10' ceilings.
I purchased one of these at Christmas with my lathe purchase but now I want to add the shroud but cannot find it separate. Can I find it or buy it someplace? I love the light it puts out but it is blinding when you turn toward it.
Keith M on Apr 25, 2017
BEST ANSWER: Rockler does not sell a shroud for this light, nor do I know of anyone that does. Rockler does sell a light with a shroud which I have purchased. The light is perfect for detail work. It is the same kind of light as you have but it has a shroud..
How do the big bulbs (59729 and 51069)
compare to a standard 100 watt bulb?
John B on Nov 29, 2017
BEST ANSWER: It provides a lot more light from what I have experienced. Don’t remember exactly but I recall it has significantly more lumens which is how you would compare the relative light output or candal power. I also should add it is a huge sized bulb but works well for my needs.
Who is the manufacturer of these large LED bulbs?
John C on Jan 24, 2017
BEST ANSWER: These bulbs are a Keystone Group Product in Erie CO. Made in China
What are the dimensions of the bulb? What are the watts?
steve on Jan 24, 2017
BEST ANSWER: This bulb is huge, it's the size of a pineapple! I believe it is 50 watts but over 4000 lumens. We have a small rustic and dark shop and this one bulb turns it to daylight. It was so bright it took awhile to adjust to it.
Will these fit in an outdoor floodlight fixture?
Robert on Dec 9, 2016
BEST ANSWER: 0nly if the fixture is well secured and the fixture doesn't have an enclosed/size-restrictive bulb housing. These lights are substantially larger and heavier than a normal LED bulb and didn't fit my garage fixtures.
will this work outdoors?
smurray on Nov 27, 2016
BEST ANSWER: I use mine in my workshop and it works very well. The description states it should not be used below -4 F so I would assume that out side use would be ok if it does not get colder than -4 in your area and is placed out of the direct path of precipitation.
