Replaced 60 Watt clear incandescent standard bulbs in a 3 light fixture over a bathroom mirror. Got tired of the incandescents burning out frequently. Color is fairly close to the warmth of the incandescents. I find them ever so slightly green, but it's barely noticeable. The wife hasn't said a word, so I'll call it a win. No delay, instant-on. At a "40 Watt Equivalent" they are essentially the same brightness as the 60 Watt bulbs they replaced. I think the "60 Watt Equivalent" LED version would be way too bright.I've been slowly replacing bulbs around my home with LED's, particularly if they have a tendency to burn out. So far I've switched to Utilitech LED's for a heavily used kitchen counter light that doesn't vent well, my front door exterior lighting fixture and now these Bioluz LED's for my master bathroom. I'm particularly sensitive to color, so I'm always looking to match the light of a typical 2700K bulb. I got the Utilitech bulb originally because it's what Home Depot had in stock. I've been very satisfied with that in my kitchen. The second one at my front door is just OK. It doesn't match the low voltage yard lights as well as I'd like. But it's close.All 6 Bioluz bulbs came packed well and in working order. I'll report back if there are any durability issues over time. This will be a good test of a very humid bathroom that sees a lot of activity.UPDATE: After a short period of use, I tried replacing these bulbs with much more cost effective 60W Equivalent Philips LED 2 Bulb Value Packs from Home Depot ($5). I've read conflicting reviews of the Philips, but I find their color more true to an incandescent bulb, with no green hue. Other than obviously being brighter and listed at a 10 year life expectancy, rather than 23 years claimed by Bioluz, there is no real difference, including the 3 year warranty. I was all set to return these Bioluz bulbs, BUT alas, they didn't pass the "wife test." She mentioned the new bulbs were too bright, and asked me to put the Bioluz back. I'd be curious to see a 40W Equivalent Philips LED, but as of yet they don't offer a Value Pack to complement their 60W.I've uploaded a couple photos showing the bulbs. It's hard photographing light really, but I think this does give a reasonable representation of what to expect. The picture with 3 bulbs has the Philips on the left, Bioluz in the center and a standard Soft White GE 60W bulb on the right. The picture with 2 bulbs compares the Philips on the left with the Bioliz on the right. I found the Philips to be a truer white light, but it's not a really fair comparison as it's rated brighter. Compared to the standard 60W GE incandescent bulb, the Philips was pretty close, but a bit cooler.
