Techntrek, last month I purchased 3 interior LED flood light bulbs (60/75 watt equivalent) in Costco which replaced 3 indoor incandescent flood lights.  I was concerned about heat in an IC recessed fixture. New bulb was totally glass enclosed (cost about $20+ US) and I was VERY impressed that it did NOT run very hot. Dimable too.

I don't know if this is new technology or just packaging technology. Have you seen these?

Marwayne/Outbound,  what's the nomenclature for the round 9 LED you are using? I'm trying to locate it online to measure its output in lumens. Thanks, Bill

LEDs indeed get warm, or aren't putting out much light and if they get hot they will fail very soon. Life of the LED is inversely proportional to running temperature, so a reputable LED manufacture will ensure the proper heat sinking path and Airflow. Really we shouldn't use a LED bulb, but a replacement LED fixture as LEDs need airflow and incandescent fixtures tend to restrict airflow.

Admittedly, I never took a multimeter to the stock bulbs, but they were labelled 7 watts and I have no reason to distrust that. The new LED bulbs that I ordered are definitely 2 watt - there were lower wattage bulbs available, but I decided to go with the higher-wattage bulbs from past experience with LEDs. When I received the new LED bulbs, I checked out the amp draw and lumen output on my bench at home (admittedly, I used the light meter on my cell phone to measure the latter, but it's not bad)

Outbound, I tested the 921 incandescent bulb it drawes 25 watts LED replacement 1.7 watts.
                                  C194 markerlight drawes 3 watts LED replacement 0.2 watts.

Buy price....buy twice!  Thebulbs like Marwayne posted are better and worth it.  No needed adapters, tape, etc.

Glad nothing bad happened out of it.  I had one of the bunk light covers melt from the standard bulbs.  Those bulbs were mini-heaters.

As others have said, you get what you pay for. And sometimes you get burned...Literally!  I tried some of those cheap Chinese units and found them totally inadequate. Junque. But then, I didn't lose much.

I replaced all my lights with LEDs from SuperBrightLeds.com. Yes they are more expensive but they work and are very acceptable as far as brightness and color go. They are slightly whiter than the 921s, particularly as the 921s age and turn black, and I like them. The SuperBrights plug like a bulb with no tape required. They also appear to have regulator circuitry built in so the brightness and power should be somewhat independent of battery voltage. The individual LEDs are 5050 SMDs which seem to be one of the best available. See  the ones I bought at:

I've got similar bulbs to marwayne and I really like them.  They're warm white and a fantastic replacement for the stock bulbs.  I'm well into the second year with them and they're holding up strong.

Mine are 2 watts, so they consume 30% of the power of the stock 7 watt bulbs while providing plenty of light.

I ordered a pack of 10 off of eBay (the seller is in China)... I won't mention the price - I'll just say that they were very reasonable.
