Hi Douglas, I apologize for the delay in response. BR40 bulbs will not fit into a 4" recessed housing. To my knowledge, I've never seen a housing that can be expanded to accommodate for bigger bulbs than intended.
Hi Greg, With little to no space around the bulb, this will trap any heat produced and can potentially reduce the light output, shorten the lifespan of the bulb or cause the bulb to fail.
What LED lamp should I use in a kitchen for both perimeter and island lighting to adequately light the countertops? I will be using under cabinet lighting also around the perimeter. PAR or BR? I am also looking for lamps with high CRI. These bulbs will give a more general and consistent lighting throughout the room. I've got a bit of an unusual situation or maybe not. I have a number of recessed lights throughout my home that are difficult to get to due to 13 and 18 foot ceilings. A ladder will only get me so high, and the extension poles with the suction cups don't work for me.
The second part of this challenge is that all of these lights have BR40 bulbs, and there is a round white metal plate with an internal 5 inch diameter that sits flush to the ceiling due to two springs. So, even for the areas with the lower ceilings, it's very hard to get a good hold on the bulb to twist it out and replace.
I never considered a BR30, as I figured it would look bad with all the excess space between the edge of bulb and the white round plate. So, any suggestions as to whether the BR30's are an option? Also, any suggestions on how to reach the 18 foot areas? Hi I was wondering if one can use "Indoor Br30 by Philips" outside in exterior recessed lightings around the house?
Will there be any consequences in using an indoor bulb outdoors? Hi Sam, There are a few things you should check before using this bulb outdoors: 1. What is the starting temperature for the bulb? Some bulbs cannot be used outdoors because if it gets too cold, they will not turn on. With LEDs, this is usually less of an issue.
Is the bulb damp location rated? If this bulb is not completely protected from the elements, the life of the bulb could be compromised by using it outdoors. And to confirm, if you are installing new cans no prior recessed lighting installed , you don't need to install any trim with the cans because the Hue downlights are both the trim and integrated LED, right?
However, after watching a video of these being installed, I'd recommend the 6" can which allows for a little more room when working to install the retrofit into the housing can. All you'll need is the retrofit and the housing. Hi Kimmy, happy to help! If you run into any further issues and have questions, please give our Customer Service Team a call at I selected these mainly based on advertised life span of 22 years 25, hrs.
However, after only Hi there, JJ. Unfortunately, I cannot speak to the quality of the first brand purchased since we don't carry it at Lighting Supply. However, a few things that could affect the life of your bulb are the quality of product and the space left around the bulb in the canister.
If the bulb fits too tightly, the heat cannot escape as easily and will shorten the life of the lamp. I hope the second bulb chosen lasts longer or that you can find a different LED brand that will work out better. If you should have further questions, please give us a call at If you have recessed cans for lighting in your home or office and need to replace the bulbs, you may discover that there are several options to choose from. If you want to light a more specific area, for instance, you might choose a PAR shaped bulb, which more sharply focuses its light.
In the names of these bulbs, BR refers to a bulged reflector; this shape is used to evenly spread light, which is why these are used for general lighting. Or more simply, the BR30 is just under 4" across and the BR40 is 5" across. So when you're choosing a bulb for recessed cans, the first thing to know is the size of the cans. For general lighting, most cans are 4" or 5" or 6". For 4" cans, you cannot choose BR40 bulbs -- they're too big. For 5" cans, a BR30 will fit with a little space to all sides while a BR40 will fit with little to no space on the sides.
For 6" cans, a BR30 may leave so much space between the bulb and trim that you don't care for the look, though this is a personal choice.
Ceiling height is another traditional consideration when choosing your bulb; BR30s are often used on lower ceilings with BR40s on higher ceilings. If the bulbs are equal in wattage, this may not make much of a practical difference; but BR40s commonly come in higher wattage options, helping them spread light across a room from that greater height. Arguably, with the same beam angle but a wider lens, BR40s spread light a little more widely than BR30s.
This could affect your bulb selection based on purpose of the lighting and distance between the cans. But practically, this is likely to be a subtle difference, and we recommend choosing primarily for wattage or lumen output and the size of the cans. The big claim to fame for LED lighting is that it operates on far less energy to produce lighting equal to an incandescent or halogen bulb. This means it costs a lot less to run and, at today's LED prices, an LED replacing a frequently used incandescent bulb will often pay for itself in years and then start putting money in your pocket for years to come.
But the last push for energy efficient lighting with CFLs left a bad taste in many people's mouths -- yes, those bulbs saved money on electricity, but they had some drawbacks too.
But let's take a quick look here at how LEDs and incandescent bulbs compare: Similarities: Like incandescent bulbs, LEDs reach full brightness immediately. Both work well in a wide range of temperatures, and both are free of mercury.
Lifespan: Some LEDs are only rated to last to 10, hours; many are rated to last 25, hours and more. Compare that to an incandescent rating of hours. Those who remember that CFLs didn't live up to their 10, hour claims, LEDs aren't affected by the same things like frequent on-off cycling or cold temperatures. So if LEDs are made of quality components, they should often last this long. Dimming: Incandescent bulbs are masters of dimming.
Most LEDs also dim check the packaging , but they need compatible dimmers. Otherwise you may run into flickering and buzzing. Some LEDs like this BR30 get a warmer look when you dim them to mimic incandescent bulbs; again, look for this feature on packaging.
Durability: As you know, incandescent bulbs are pretty delicate thanks to the glass bulb and the thin filament. Some cost more and come with a better supported filament and shatter resistant bulb. But LEDs -- which have plastic bulbs and no filament -- are durable from the start. Heat: As you also know, never unscrew an incandescent bulb that was recently turned on or you can burn your hand.
LEDs stay cool the touch on the bulb portion, though their heat sinks toward the back get hot. Due to their need to dissipate heat, LEDs also need some air flow, so check the packaging for compatibility if you plan to use an LED in an enclosed fixture.

The main difference between the 2 is the beam angle of the light. BRs spread the light with a degree beam angle, while PARs create a focused light with 40 degree beam angle.
What is the difference between par20 and par30 light bulbs? Can I use regular light bulbs in recessed lighting? A recessed fixture with a medium screw base lamp holder can take an incandescent, fluorescent, halogen or LED light bulb. If you want to be able to dim your recessed lights, or control them with a remote or automated system, choose fixtures you can use incandescent, halogen or LED light bulbs in.
What are reflector light bulbs? Incandescent reflector bulbs contain a reflective coating and therefore provide directional light. The shape of the light beam is cone-like and can be specified in a range of beam spreads from narrow spot to wide flood.
Reflector bulbs fit into the same medium-based sockets as common incandescent bulbs. What is the difference between br30 and r30 light bulbs? The difference is simply the diameter of the bulb.
R30 bulbs are the larger of the two bulbs. BR30 bulbs are actually the newer, more energy-efficient version of R20 bulbs and are the same size as R20s.
