From what I've been reading it looks like these replacement tubes actually get hotter than the normal flourescent tubes. Is this true?

Not that we have ever noticed. We use them in our RV and have been wonderful!

My understanding is that these bulbs are good until they stop working, in other words if they are lighting up they are still effective unlike the old flourescent tubes. My lights are over a year old and still going strong in this unit, excellent plant growth and a pretty tank.

These are much better. I've had them in quite hot microwaves with no melting. (No doubt the venting helps too!) I think you'll find that they'll do the job for you just fine.

I had one burn out earlier this year, I found a 180 watt tube on EBAY that was sent from China for about $13.00, unfortunately I never received it. I had to fight a little to get my money back, but I haven't tried buying it again yet.

The new model can get as hot as the old one (which I also have)...I just missing fine tuning the temp manually rather than using the LED set temps.

Yes I have used them before and they do show a little heat when they have been running for a long time to reach temp. It should not however be super hot or smell hot. But, some heating is normal As long as you are within the 240v limit and no more than 10 amps all is fine. If you are using a normal 240v then you would be at 10amps. Hope this helped. If not get a hold of an electrician and check the heating circuit. This unit should handle it

I haven't noticed that they have any sort of cooling effect. It may just be that they have better ventilation than other products, but for me I have found that I do get hot in them from time to time.

You really can't tell they give off any heat at all, I've never noticed them to be excessively warm. You can use an LED instead but I have yet to find an LED that doesn't really stick out in that lightbulb design, the LEDs have a lot of plastic in their design as opposed to the halogens that have a sleek, metal look to them.

Yes, I have had them on for a few years and have worked flawlessly. I had pumps that cycled every two to three minutes using a float switch and burned out fairly regularly ( and not cheapo pumps). Using these I was able to increase the "float" range and now my pumps cycle every 5-10 minutes although they do run a little longer. Fewer start cycles seems to be a lot easier on my pumps and they are lasting much longer

Silverstars especially the high end HID equivalent are brighter than these. All light output in this type is usually rated in Kelvin. The hotter the burn of the light source the higher the Kelvin (usually) all meant to be toward 5000 to 6000 Kelvin or natural sunlight temps/light equivalent. In my opinion, the Phillips cast a cooler blue light usually associated with a 3500 to 40000 Kelvin scale. I ran them for about 3 weeks and went back to Silverstar HID equivalent for these very dark, no street lights, out in the country roads.

They get warm but not hot. I would think the worse that might happen is the plastic might yellow after years of being warm.

We love these LED bulbs and have 8 of them in our motorhome. But when I measured the amp draw, it was not much less than the T8 florescent bulbs they replaced, and the backside still got warm. But the light output is much greater & whiter than the fluorescents they replaced, and they are a well made bulb. I think to get the brighter light, the many LED's are 'pushed' which accounts for the amps not being as low as other LED lights that have fewer LED's. The back side is a heat sink so that is why it is warm.

They don't burn hot. They get hot like any other bulb sold out there. There isn't any torture on the wiring. I have had them for quite sometimes now. They've been great.

I've mostly seen these used on stage lighting, which is hot. Generally they hold up well, but they can warp and melt if they are pressed directly against or too close to a hot light. If they have a bit of airspace between them and the light they seem to do pretty well. But I suspect there is variability across manufacturers, and the darker gels will get hotter than the light ones. My impression is that you will see warping before they up and actually melt on you.

Can't answer precisely because I don't have the specs on your existing tubes. These are 3000k color temperature which is warm white not the garish blue white of higher color temps. Light output should be the same...they are both 32 watt.

I used these in my kitchen paddle fan to maximize the light output. The shade is open on top so heat build up wasn't a problem. If you are using them to replace an incandescent bulb they should be fine. All incandescents create more heat then fluorescents so that would represent a heat reduction. If you are using them to replace a smaller fluorescent bulb in a tight enclosed fixture, logically a larger (more watts) creates more heat then a smaller one so its more conceivable that it could create more heat then the fixture could handle. A fixture with a real ceramic socket is more tolerant of higher heat. You might want to buy one bulb and see. I used these in my kitchen paddle fan to maximize the light output.

When I plug in the ones I have they get fairly hot within an hour or two. That's how I know it's working. The heat is necessary to evaporate the moisture from the silica crystals. I recently recharged a couple that had been neglected and it took three days to evaporate all the water out. I'm happy and very satisfied with the units I have so far.
