This light bulb generates very little heat compare to conventional light bulb. It generates little less heat compare with CF bulb. I can touch the bulb with my hand and just feel it warm (not HOT). Don’t know how birds are sensitive to it when it’s on. But one good thing with LED light bulb is that it’s not packed within a thin glass envelop (unlike the conventional light bulb or CF light bulb), so your bird won’t break it.
I don't have this exact one, so hopefully some who does will respond... But some I do have with the same specs do run hot, even in wide open space. Not as hot as incandescent, but hot none the less.
I was worried about how the lightning temp was going to be as well. They are pretty much white white. Like almost daylight looking. Not a yellow or orange tone at all. At least not where I have the bulbs. I do have light grey walls though. Not sure if wall colors matter on LEDs or not. Hope this helps.
As of right now, the 800 Lumen bulbs are going to be the upper end in terms of brightness without spending significantly more money. There are apparently new LED bulbs that are coming to market in the near future that will support 3-way. I haven't personally seen an LED bulb that is an appropriate replacement for the 3-way yet.
One thing that many people may not know, is that the 3-way bulbs are not part of the "incandescent ban" that is in place, so there should still be availability of these bulbs.
I haven't seen any bulbs rated to compare against 150w, though they may exist. Really the best comparison is lumens, not wattage, but you should perhaps try the highest lumen output bulb you can find. I have bought quite a few, and feel that many that are rated comparable to say 60w, seem to be as bright as 100w bulbs. They really 'pack a wallop!’ So try an 800 lumen or higher, and you might be surprised the amount of light they put out.
I have old style fixtures that have a glass globe or cover that fits against the metal base affixed to the ceiling. The glass is held in place with screws and is removed to replace the bulbs. We have used incandescent bulbs in these for years and more recently CFL bulbs. Since LEDs are supposed to be cooler than both of these, i would think they could be used in these fixtures, yet on a package of 40-watt equivalent LED bulbs that I bought elsewhere, it said not to use in enclosed fixtures. Do these have the same warning? Thank you.
*Suitable for use in open fixtures. *Not for use where exposed to weather. *Turn off power before installing. *Not intended for use with emergency exit lights
I used two to replace "regular, old fashioned" 60-watt bulbs, in a light fixture that is attached to a ceiling fan. I don't recall anything about not using them in enclosed spaces, so maybe that will be a problem somewhere down the road, but so far there has been no apparent problem with this.
The 800 Lumen LED bulbs use 13 watts. The estimated yearly energy cost is $1.57 based on 3 hrs/ day at 11cents/kWh. They use more than 75% less energy than a 60 watt incandescent bulb.
I had the same question. Went to insignia's website, and from what I gather the NS-LED60F was the previous version with a slightly higher wattage than the A19. They both have the same number of Lumens, but different wattage and design.
